Keweenaw Ledge Agate-AKA SISU Agate

Visiting the Seaman Mineral Museum is always a treat. Their Fluorescent display is shown.

The Keweenaw Peninsula always amazes us. We have had the most wonderful couple weeks. Business has been robust, with loads of lovely ladies sporting our jewelry made from local Copper Country rocks. We pulled into our new campsite at Lake Linden last night, and while I was talking to the campground

The Pink Petoskey Stone and the Favosite I donated to the Seaman Mineral Museum.

host, I told her I sold my jewelry at Copper World. She said “Are you the guy that makes that amazing wire wrapped jewelry”. I admitted that I am and she told me that someone was in the campground who had a new Lake Superior Agate necklace she had bought at Copper World. It is so nice to get complements like “I could not believe that was wire wrapped jewelry, it was so perfect.” How nice is that? Coffee and a complement first thing in the morning–a great way to start the day.

Bon nie chats with some customers at the Eagle Harbot Art Fair.

I expect since it is a perfect day, I’m just going to relax and make some jewelry in my lawn chair.

This last week we started digging a hole in some hard rock ledges south of Copper Harbor, and we struck the mother lode of Ledge Agates like I have seldom been seen. This is a special type of Lake Superior Agate not as well known as the traditional fortification (or banded) agate. I was finding this agate in seams rather than in nodules, or single rocks.

Here I am "slamming" agates out of a ledge. I call these SISU Agates, because they are so hard to get.

The normal Ledge Agate is a dull brown or pink/white, non-banded, drab agate, but some of these are bright red, some with white Quartz. I have been literally working my meals off in this hole. I have a special “slammer” tool my buddy Chris made for me. I cannot imagine how much harder these would be with a chisel and hammer. I did dig this hole: bend and twist, sweat and ache. I saw color and from a deathlike state I come back to life and kept beating at the rock. The local Finns have a word for going above and beyond your ordinary: SISU. I am definitely in SISU working on this hole-struggling above and beyond. I hereby dub these SISU Agates!

Agates in the hole.

I guess I am in the Agate Greed mode right now, so we will go get more the next couple days.

A whole bucket of SISU Agates.

Finally the Monks at the Jam Pot had a full supply of their famous Muffins and other goodies.

Greenstone Hunting Plus Fun and Funny Adventures

Chris Cooper makes a tool he calls a "Slammer". It is much more precise, easier, and lighter than a sledge hammer. I love it.

Our current trip to the Keweenaw Peninsula is fun filled with hunting rocks and gemstones that I can make jewelry from, Wire wrapping demonstrations at our retail outlet, Copper World, in Calumet, and art shows in Eagle Harbor and Copper Harbor.

The awesome Copper World

The awesome Copper World hosted me for a couple days, and honestly we were selling jewelry as fast as I could make it. I love chatting with the tourists and locals about Copper Country jewelry and the local rocks and minerals that my pendants are made from. You can always tell the locals (they actually know what Datolite is) and we know many of them that are faithful customers year after year.

Doing my job at CW.

Greenstone (Chlorastrolite) is one of our staples on our website and here in the U.P. We have been concentrating on finding some of this rare gemstone the past couple days, but it is just not easy to find many good gemstones anymore. The good spoil piles from the copper era have been gradually crushed and hauled off for road fill. It is all very depressing. We were signed up this week for a paid hunt at the Central Mine, but it was cancelled because crushers and equipment have been moved in to destroy and remove the piles.

The impossibly rare Blue Datolite from Centennial #2 flies out of the display case at Copper World.

Wouldn't you think there were some Greenstones in this pile of poor rock? They are so hard to fine.

I think these waste piles are an historic treasure in the Keweenaw, and when they are gone, so is the history of them. The Seaman Mineral Museum (Michigan’s Official State Mineral Museum) sponsors hunts this week in an event called the Copper Country Mineral Retreat. We pay for heavy equipment to stir up the piles we have rented from the landowners. Treasures in them are then searched out.

This little bag of Greenstone suspects might produce a couple good ones.

Jacob's Falls

Also we went to the Jam Pot, a bakery run by the Monks (yes real Monks), between Eagle Harbor and Eagle River. We got there at 2pm, thinking there would be a good selection left..NOT. They were pretty much sold out of all their famous, big, tasty muffins. I have withdrawls for Carrot Raisin Muffins. Bonnie found sone Hermit Cookies and some Apricot Muffins, and I found the amazingly decadent rum soaked brownies with raisins and nuts. Right next door is a waterfall (Jacobs Falls) that you can walk over and appreciate.

The strangest thing that happened thus far: I swear this is true: We see a day glow sign advertising a yard sale. There was so much writing on it you would have had to stop in the road and spend 10 minutes reading the fine print. Bonnie saw the word “Copper” so we headed down the road where the sign pointed. Possible error in judgement after 5 miles. What the hell. let’s see where this goes. After 10 miles we see the sister day glow sign on a pole and a front yard landscape comprised of lots of random scrap metal things. The sign had printed (scribbled) on the bottom: (entry fee $2)..If you buy something you get your $2 back. Only in the U.P. has there ever been an entry fee to a yard sale. I spent $4 worth of gas to get there. I should have stopped and charged him $2 to make us even. I think I go up after dark and add a sign that says, “Entry fee ONLY $2”. By the way, I turned around in his drive and back to town we went.

We’ll probably get out today for some hunting and back to Copper World tomorrow. Come see me if you are up here. The adventures continue..stand by.

Greenstone, Datolite, and Michigan Wire Wrapped Jewelry

In preparation for upcoming shows in the Upper Peninsula I have been working on some U.P. Gemstones and Jewelry.

Centennial Blue Datoite (and one from the Isle Royal Mine)

First was the cutting of very rare blue Datolite for the Centennial Mine north of Calumet. The mine hoist is still there, but the piles are gone and Centennial #2 is completely flooded. Any Datolite still found from this mine has been hoarded from the 60’s.

Blue Centennial generally contains microscopic grains of copper shining through the blue Datolite. Over the last few years Centennal Blue has been almost impossible to buy from anyone.

Copper Included Datolite is very popular in the U.P.

I’ve been holding on to assorted Datolite containing Copper Inclusions. I finally cut and polished the majority of the pieces I have. These always make popular jewelry for my Upper Michigan customers. Even those snobbish jewelry buyers love Datolite with Copper.

Copper Datolite with Greenstone...BAM!!!

Could it be a new ring?

I also cut three remarkable little Cabochons for a future ring for myself. The ring will sport a Yellow Keweenaw Point Datolite with copper, A Copper Agate from the Kearsarge Lode, and a copper Included Greenstone. This ring will be over the top when it is finished. I’ve got to cut the wax for the ring and I have a friend that will cast it for me. Notice the “Thumbs Up” from the Yellow Datolite.

We’re headed up north for rock hunting and shows shortly. Check our home page for upcoming events. It’s always fun for us to see all our friends in the Keweenaw. Come see us at Copper World in Calumet and art shows in Eagle harbor and Copper Harbor or on a rockpile nearby.

A Lake Superior Agate of the "Paint" variety was a quick sell off our Facebook Page.

Greenstone Bonnie

Bonnie was the Greenstone Queen on a recent collecting trip to the Keweenaw.

The Greenstone Queen hold some of her best ones.

I was scheduled to demonstrate wire-wrapping for a couple days at the awesome Copper World in Calumet. I really enjoy making jewelry and visiting with customers, many of them old friends after purchasing Snob Appeal Jewelry over the years. Bonnie went digging Michigan Greenstones (chlorastrolite) while I was busy at CW.

You never know what you have when it comes to Greenstones in the rough. She did dig up quite a few suspects. We went out together the next day and she again out-hunted me.

The spoil piles where we used to just find nice Greenstones left and right are mostly gone, being crushed up for road fill. Right now much of the crushed rock is being used for logging operations. Isle Royale Greenstones, particularly good ones, are getting much harder to find every year. We are just thankful we still have some for sale. I have also noted that these rare Gemstones are not only popular in the Upper Peninsula, but we have sold them to customers in several States. I think some savvy people are noting that these little green beauties are one of the most extraordinary gemstones on earth.

Here is the almost finished Greenstone.

I came home and cut out stones. Most were small with varying quality. Bonnie did find one Quarter sized stone that had a thin, but perfectly patterned layer. I carefully worked this stone to develop its’ pattern. Cutting Greenstones is exceptionally challenging. You have to know precisely when to stop or you will cut right through the pattern. There is a razor thin line between a perfect cut and a worthless stone. Slow and careful is the secret.

After a slight re-cut for balance, I finished this one. Pretty nice!

I ended up with a very fine, chatoyant beauty, of 4 grams. The biggest Greenstone she has ever found, and a real showpiece.

I re-cut the cab slightly to make it more uniform, than wrapped it in Pink Gold and Gold Gold. The Greenstone’s huntress was very happy.

I also found two very large Greenstones with Pink Prehnite inclusions that I purchased. These two stones came off Isle Royale between 1932 and 1942, before Isle Royale was a National Park.

At 8 grams each, these are museum sized beauties with a good story. You seldom find anything like this anymore.

I was told that the area where these were found is buried under a path that the National Park created. The stones were found by a family that rented cabins on the island back in the day. Somebody is going to acquire some nice Isle Royale Greenstone jewelry when I wrap these.

Bonnie done those Greenstones proud. You gotta love a woman that doesn’t mind getting dirty, and looks good doing it.

Not much of a city anymore, but hopping during the Copper Era.

Mohawkite, Domeykite, and Algodonite

As I look at these names, I think what an unfriendly sounding bunch of names. I make natural stone jewelry out of this? How about calling it Silver Bullet or Shining Golden Bridal Stone? Instead this mineral has a name that reminds me of a donkey.

Gold Ore or Mohawkite? A real fooler.

Mohawkite was/is one of many local names for a copper ore comprised of Copper and Arsenide. The two primary Copper Arsenides in the Copper Country are Algodonite (Cu6As) and Domeykite (Cu3As). Between 1900 and 1901, 105 metric tons of Mohawkite were taken from the Mohawk Mine. Enormous masses of Algodonite also came out of the Ahmeek Mines. This area is on the north end of the Kearsarge Lode.

A silvery slab of Mohawkite. Siver coloration in probably due to high Nickel content.

I have sort of a love-hate relationship with any of these Arsenides. Allow me to explain my love-hate relationship with Mohawkite. Mohawkite is a local name for a mixture of Algodonite and Arsenian Copper found in the Mohawk and Ahmeek area Copper Mines. This material has been called many names in the past, and even today we hear solid pieces of Mohawkite called “Butchite”, another example of a local moniker.

Iridescent Mohawkite. The picture does not do this justice with it's metallic reds and Cobalt Blues.

While I love all the Keweenaw Mining District stones, like Greenstone, Datolite, and Prehnite, I dislike working with Mohawkite or any other Copper Arsenide. After cutting Mohawkite I seal the material using a lenghthy procedure I’ve developed over the years. After any Mohawkite cabochon is sealed it becomes perfectly safe in normal use.

What I do love about these Copper Arsenides is they are absolutely gorgeous. When this arsenide is intermixed with white Quartz, the effect is amazing. It makes beautiful jewelry, and has this ability to be, and look, like several other things. For example, it’s a real fooler when the golden Mohawkite couples with the white Quartz. You would swear it is Gold Ore from California. Customers love the jewelry I make from Mohawkite, and because it is found nowhere else on earth, it is another keepsake from the Copper Country that is totally unique. I suspect that the amount of Nickel, Cobalt, or other trace minerals in the Mohawkite causes some of this stone to remain stable in color, while others change to gold. The Arsenides are the cause of the iridescent phenomenon. I have found that in stones that contain a high level of Arsenides, the color change is almost instantaneous.

By sealing the stone, any potential toxicity is eliminated. The possibility of the stone tarnishing is prevented by my sealing process also. I think of Mohawkite as a Chamelion of sorts. When I get a cabochon shaped, I never know how it will react to oxygen. I cut some today that became iridescent within 5 minutes. I wanted a golden color so I went back and re-ground off the rainbow. The metal was silver in color when it came off the grinder. I put the cabs in water, and rushed them to my sealing area. I rapidly removed them from water, dried them. When I wiped them dry, they immediately changed to a golden color. I sealed them in time to inhibit them from changing to iredescent colors. I did leave several cabs to for a few minutes and sealed them when they rainbowed.

You see very few people making jewelry from Mohawkite, but I love the unusual look of it, and we sell many pieces of it. After my sealing process, the stone is perfectly docile and safe to wear.

My Mohawkite jewelry is popular at Copper World in Calumet, Michigan, I also sell this material on line. Mohawkite is challenging to find anymore, but occasionally I stumble over a good piece while exploring the piles. Remember that these Mohawkite mines are all on private property and should not be hunted without permission.

We specialize in jewelry made from rocks and minerals of Michigan, and Mohawkite is one I love to hate. You on the other hand will love it, especially when you get all those complements.

Datolite-A Borosilicate to be proud of

I always keep several hundred cabochons in my inventory, ready to be made into fabulous Snob Appeal Jewelry. After I cut my cabs I carefully place them in boxes, trays, or perhaps just lay them gently on the dining room table (this my wife is not fond of). She is misguided in thinking that the dining room table is only for dining on.

The workbench was a mess today; not to worry; I'll just put stuff on the dining room table.

Fortunately she is married to a husband who thinks outside the box and can utilize the dining room table for several things at once. The table is an ideal place for putting new and old jewelry that may be in the loop for cleaning, posting up, washing, remaking, or just to lay somewhere where it “won’t get lost”. The issue sometimes is that the jewelry can get covered by several layers of newspapers or mail; then I either forget it’s there or lose it. That being said Bonnie enjoys saying things like: “Are you missing this?’, or “If you’d put it where it belongs, you’d be able to find it.” Comments like these disrupt the serenity of my retired life.

Today I went in search of my favorite borosilicate, Datolite. What is your favorite borosilicate? I re-discovered a beautiful pastel, copper-included Datolite from the Mesnard Copper Mine in the Keweenaw Peninsula of upper Michigan. The Mesnard mine was near the Quincy Mine but it seemed that the finest Datolite colors of yellow-orange, pink, and red came from the Mesnard. The Mesnard waste piles are now owned by a gravel company and are no longer available for hunting, making Mesnard Datolite ever more rare and more coveted every year.

I love this Mesnard Datolite.

The designer shape and the coloration of this cabochon warranted a tri-tone wrap. I used gold, Argentium silver and pink gold for the wraps. The pink gold beautifully draws out the copper inclusions in the cabochon. I love the dancing sunset colors of the stone. A picture cannot do justice to the true colorations of this remarkable gemstone.

A bonus Mesnard Datolite.

The most common white Datolites are still out there, but colored Datolite is dwindling. The only place to find these fine old pieces of Mesnard are from old collections, and even these are becoming very limited. Fortunately someone who has inherited an old collection, or has an old collection and needs some ready cash sometimes approaches me. I really appreciate how hard these gems are to locate both then and now, and I am always trying to keep a good variety of Datolite jewelry available.

If you enjoy rare gemstone jewelry or have ever sought a piece of Datolite Jewelry, you should act now before there is no more of these beautiful rare hues available. Many a Mesnard has vanished in the piles on my dining room table, increasing the shortage of my favorite Borosilicate.

Inside the A.E. Seaman Museum

The A.E. Seaman Mineral Museum

I thought you would like to see a small sample of what you would see when you visit the A.E. Seaman Mineral Museum.

THE most spectacular native Copper specimens in the world.

Copper Included Calcite

The new museum opened just over a year ago under the direction of Dr. Ted Bornhorst and Curator Dr. George Robinson.

The famous "Grasshopper" (Native Copper)

The Seaman is Michigan’s Official State Mineral Museum, located on the Michigan Technological University Campus in Houghton. A brand new museum building houses one of the most remarkable collections of rocks & minerals in the world.

Tourmaline

There is no other museum, including the Smithsonium, that houses the premier collection of Upper Peninsula Minerals that you see at the Seaman. Also you will not want to miss the amazing fluorescent display room, and the many “best in the world” specimens scattered thoughout this museum.

All the new, locally manufactured, custom display cases seem to be a perfect fit, and the lighting in the Seaman Museum is just perfect. Much thought went into the entire structure, except,”what do you do if you hit an old mine shaft during construction?”. You can read the interesting story from the building construction at The Mining Gazette. And you know the story eventually had a happy ending!

One of the Mineral Galleries at the Seaman

Pegmatite Display

A temporary display on loan from a private collection.

Many people, from around the world, make a pilgrimage to this out-of-the-way locale just to see this world-class museum. YOU would be remiss if you missed this marvelous and incredible museum. You might even have a Pasty after your explorations in the A.E. Seaman Museum.

A Donation to the A.E. Seaman Mineral Museum

Anyone that knows me, knows that one of my favorite places in the world is the Keweenaw Peninsula. It is a beautiful, historic place, as well as my best rock-hunting area.

The New A.E. Seaman Mineral Museum.

In Houghton, on the campus of Michigan Technological Institute is one of the great mineral Museums in the world, one that, unfortunately, most tourists pass up. The A.E. Seaman Mineral Museum located at 1404 Sharon Avenue. The seaman Museum is Michigan’s Official State Mineral Museum.

The Seaman moved to their new building last summer. The new building is still lacking the space to display all the museums collection, but it is all they could afford when forced to move from their old space in central campus location. The new museum building has room for expansion in the future.

Donating my Pink Petoskey Stone to Dr. Robinson at the Seaman Museum. I am pointing the case where the specimen should fit.

The curator of the museum collection is my good friend, Dr. George Robinson, who also teaches some of the geology classes at Tech. The director of the Seaman is Dr Ted Bornhorst. Based on all the work done in moving the specimens, and setting up all the new displays, I would also point out the work done by George’s wife, Susan. You might as well call her co-curator.

The new museum opened officially in August 2011. I told George that when the museum opened, I would donate a world-class Pink Petoskey Stone to add to their display case containing Michigan’s Official State Stone. I took a mineral photography class in 2010 and George saw the Pink Petoskey Stone when we photographed it in the class.

The world-class favosites I donated previously to the Seaman.

I have previously donated a Favosites specimen that is on display, but it was an honor for me to share my Pink Petoskey with the world. I know of no other museum that has a pink Petoskey Stone in their collection.

You can clearly see this Petoskey is Pink!

Next time you are in the Houghton area, check out the A.E. Seaman Mineral Museum and look for my donated fossils.

I’ll blog more about the museum and show you some of the displays in the near future.

Guinness World Record copper specimen (satellite exhibit at the Quincy Mine)

Greenstones in the Rain (and other fun U.P. things)

The colors in the Keweenaw were about 30%, but we found spots. This tree was near Phoenix.

Our fall weekend in the Keweenaw was very productive.

The view from the top of Brockway Mountain indicates it will be a couple weeks before peak colors.

By going up Thursday, most tourist traffic can be avoided, and an extra day for rock hunting opens up. We found some nice greenstone at the Mandan.

Finding a nice Greenstone in all this rock is a challenge.

The best time to locate Greenstones is in the rain. The silky chatoyance just pops from the stones, both the loose nodules and those nodules still embedded in the matrix. We looked pretty wet and scruffy after a day in the rain, but it was worth it.

We had the Cliff Pile to ourselves on this drizzly day.

My favorite fall colors, maple Leaves and Greenstones.

Friday is also ‘pasty day” at the Mohawk Superettte. The locals purchase their pasties (pronounced pas-tee) in quantities, and we are happy to when we are in the area. We find them to be some of the finest pasties around. For those that do not know what a pasty is, they are a portable Cornish pie made from coarsely ground beef, with small cubes of potatoes, and rutabagas. You can find recipies on line. This was a hearty lunch for the miners, sort of an early version of fast food!

Any day is a great day to Stop in the Jam Pot and purchase a few delicious Muffins and rum-soaked, raisin and nut filled, brownies from the monks. Yum! (Closed Sundays, of course)

Makes me hungry just looking at the sign in Mohawk.

This rock ship at Kearsarge always makes us smile. Bonnie mans the ship at the Veterans Memorial.

While just aimlessly searching I saw a 3″ suspect just laying on the ground. This was just a suspect greenstone and may or may not develop into a winner. We also went to the Cliff mine, my favorite Prehnite location, and picked up some nice material to cut.

Whenever I go to the Upper Peninsula, I enjoy at least one day wire wrapping at Copper World in Calumet, and I really had a great time as usual. Talking to the customers, and answering rock and jewelry questions are a couple of my favorite things.

Sunday was another cool day with some scattered showers, we went out with some new rockhound friends. Bonnie found some nice little greenstones, and I found a very nice 2″ stone that has to be cut from a rock.

From left to right beginning at the top: Mesnard Datolite, Rose Quartz and Quartz with Copper, Franklin Datolite, Yellow Keweenaw Point Datolite, Patricianite with Silver and Copper.

While up north, I also located a source for some rare and unusual things like Patricianite with silver, and pink crystallized Datolite. Let’s see what kind of jewelry I can make.

Close-up of the Rose Quartz Cabochon.

A couple other things we did were donating a polished Pink Petoskey to the Seaman Mineral Museum (Blog coming), and I walked into Copper World Sunday afternoon and met a couple from Dayton, Ohio that had just purchased an exceedingly rare large Greenstone with a centrally embedded copper crystal, as well as a Petoskey Stone Pendant. It’s always nice to meet with owners of my jewelry. It means a lot to me to talk to them and answer any questions, and I think that the jewelry means a lot more to them when they can say they have met the artist. I could have stopped in any time, but Karma (I learned about this from Earl) brought me in at that particular time.

Patricianite with silver and copper inclusions.

Now I have some exciting new U.P. gemstones to cut, polish, and wrap up. It will be a great rest of the month.

The above stones I cut this morning. Enjoy!

Sad to Leave Copper Country

Our favorite beach to watch the sunset-just south of Dapple Grey B&B on M26 near Copper Harbor.

As the sun sat over Lake Superior on our last night in the Copper Country, we reflected on the amazing time we had. Sure there were some difficulties on the trip, and you just cannot go get everything you might need without driving 40 miles. Still, we love this place.

The same beach is scenic during the day also.

The Yoopers are a very independent species. They have to be. They have all the important things like pasties, fresh air, scenery, rocks, Vollwerth meats, Copper World, rocks, no freeways, beautiful, sunsets, snow, Monk’s Muffins, and rocks.

I have started cutting my treasures today, as well as working on some custom jobs I picked up while up there. People find rock treasures and bring them to me to cut, polish, and make into their own wire-wrapped gemstone jewelry.

We have loads of good friends in the Keweenaw, as mentioned in a previous blog. Many of our local friends show up where they are least expected. The latest was Robin from Garden Goods, the garden store we shop at in Traverse City who showed up at the campground host’s coffee hour!

Thanks for saving the crest of Brockway Mountain.

Rock hunting is not as good as it used to be. Mine waste piles are being crushed up and hauled away for logging roads. The natural beauty of the area is being threatened by all the trees being cut. Even though the Keweenaw is a National Historic Park, it seems not to matter that the mine piles are being taken away. I feel that these piles are also historical sites and should be protected.

One good sign is that money has been raised to purchase the land and save the crest of Brockway Mountain. We saw a rebuild underway at the overlook of Copper Harbor on Brockway Drive. New stone border walls and benches are expected which should make it safer.

What lovely things you see off the beaten path.

If you really want to get away you just can’t beat the Keweenaw. We’ll be headed back up for color. I expect it to be early this year. We saw trees have begun to change already. We’ll remember the good times we had in the U.P.
