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.

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.

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.

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.

Rhodochrosite on the Workbench

We have been very busy making new jewelry for the past few weeks. The Pink Petoskey (Pink Pet) activity has also taken up time with making cabochons, wrapping them, and polishing Pink Pets for web sales. At last count there are over 30 polished Pink Pets on this site; take a look. The May/June issue of Rocks and Minerals Magazine features an article by myself and Dr. George Robinson on the illusive Pink Petoskey Stones of Northern Michigan.

I called this pendant "Brazen Vista".  I think you can see why.

I called this pendant "Brazen Vista". I think you can see why.

I daily look through my cabochon collection and choose possibilities for wire wrapping. My mood changes from day to day, so whatever inspires me, I select. Yesterday a lovely rosy pink Rhodochrosite grabbed my attention.

I knew this pendant would be a challenge because it was a rectangle. Squares and rectangles are a challenge for several reasons. The cab has to be very precisely calibrated from side to side and top to bottom or you will notice the imbalance immediately. Secondly, the wire wrapping has to be dead on from side to side and top to bottom. Thirdly, wire cannot be “pulled” around corners, so squares and rectangles must be made one side at a time. Advanced skills are required for this type of wrapping. This is why you do not see many wire wrappers doing squares, rectangles, or round shapes. This type of wire wrapping is very detailed and time consuming.

I have been looking at this large (2″ X 1 -1/4 “) Rhodochrosite cab for a few years off and on. In recent years Brown Rhodochrosite has become more expensive than normal pink Rhodocrosite. Years ago the miners in Argentina threw away Rhodocrosite containing browns as unacceptable. The value of this gemstone has substantially increased for the past several years. It is difficult to find nice Brown Rhodochrosite without pits, and this quality costs $$$. The brown coloration is a result of impurities in the stone. So finally this stone has a chance to shine.

Here are a couple other items from my workbench this week.
Bonnies new Pink Pet.

Bonnie claimed a recent Pink Petoskey Stone Pendant as her own. She normally likes all the stuff I make, and is honest in her opinions of my wire wrapping. Sometimes she just really likes a piece, and this was the case here. Click on this link to Pink Petoskey Stone Pendants as I do have lots of other Petoskey Stone jewelry available for purchase, just not this one!

Beth's new treasure. Thanks for being patient.

Beth's new treasure. Thanks for being patient.

My good friend John gave me a geode slice a few months ago after we came back from the Tucson rock shows. During the Tucson unpacking frenzy I misplaced the stone and forgot about it until John asked me about it. This put me on a full alert to find it. I found a little silver cloth bag on my bookshelf, looked inside, and found the stone. I should have been looking for a silver bag instead of a stone. It was right where I put it, as Bonnie would say.

I had talked to John, previously, about putting a gemstone in the crystal cave of the stone, but was inspired when three Topaz’ fit perfectly in the pocket. Beth (John’s wife) loves her new piece of jewelry. Again, this piece is spoken for, but perhaps you would like to look at some other gems by following these links: Crazy Lace Agate Pendants, Ocean Jasper, Pietersite, or the every sparkly Victoria Stone.

Finding the Ent

It’s about time I showed you some of the jewelry I made from all that stuff I bought in Quartzite and Tucson in February. I have been working both in my shop and on my workbench.

This is just so wild.

This is just so wild.

Another really cool Bumblebee.

Another really cool Bumblebee.

One of the most popular stones in Tucson this year was Bumblebee “Jasper”. It is not really Jasper, but is a mix of minerals in a matrix of a volcanic Tuft from the island of Java in Indonesia. Most of the Bumblebee we saw was just yellow and black, but I was lucky to find one dealer that went to Java and hand-picked some of the best material that I have ever seen. These Cabochons were bright pumpkin orange and black.

Treebeard the Ent.

Treebeard the Ent.

I bought some wonderful Yellow Feather Dendritic Jasper from Utah. Dendrites are tree-like Manganese inclusions in a rock, and make wonderful pictures. The Pendant I show you in this blog stood out when I cut a slab off the host rock. I am a big Hobbit fan and I actually saw what looked like the Ent named Treebeard in it. “Hroom, hm, come my friends.” He’s taking Merry, Pippin, and the Ents in a charge on Isengard. Now where else can you get a totally natural depiction of a Lord of the Rings character for your stone jewelry?

Blue Biggs.

Blue Biggs.

Biggs Jasper is a long-time favorite with lapidary types. It is quite scarce now but back in the 60’s the famous Blue Biggs was very popular. Biggs was re-discovered while building a road, and the best that came out was Blue Biggs. The reason I say it was re-discovered is that Native Americans made arrowheads from this Jasper for many years. Some Biggs was also used for landscaping. I found a nice chunk and this pendant is one cab from this spectacular picture Jasper.

Dinosaur Bone-WOW

Dinosaur Bone-WOW

There were many sellers of Dinosaur Bone at all the shows, but when I saw a D-Bone slab with a red agate inclusion, I just had to have it for a special piece of fossil bone jewelry.

Royal Imperial Jasper

Royal Imperial Jasper

Royal Imperial Jasper has just such spectacular patterns and pastel colors. I really like this stuff, found in Zacatecas, Mexico about 50 miles north of the city of Guadalajara. Does is remind you of Edvard Munch?

Smithsonite

Smithsonite

Smithsonite from the famous Glove Mine in Arizona caught my eye. These stones had unusual colors, and made some really lovely jewelry.

It was a real pleasure to find the oldest living thing in Middle Earth in my stone pile. One of the reasons I cut rocks and make jewelry is because I love these unexpected visions. Stay tuned for the next finds!

Green Stone and Greenstone Jewelry

Drusy Quartz.

For St. Patricks, my gift to you is some of my favorite green pendants from past to present. Many of these I am very proud of as some of my best work. Join me as I look at favorite green gemstone jewelry.

Snoopy and the Red Agate

I haven’t written an “On the Workbench” blog in some time, but I thought I would let you see what I’ve done with some of the stuff I brought back from the shows in Arizona. Check the back blogs to review.

Bumblebee Jasper is not really a Jasper.  Finding bright orange Bumblebee is uncommon.

Bumblebee Jasper is not really a Jasper. Finding bright orange Bumblebee is uncommon.

One of the things that seemed all over Tucson this year was Bumblebee Jasper. This orange and black (but usually yellow and black) rock comes from Volcanic vents on the island of Bali in Indonesia. It is a mis-nomer to refer to Bumblebee as Jasper. It is neither Jasper, nor is it an Agate. The rock is in reality an Anhydrite/Sulfur/Hematite with welded volcanic tuft (ash). This stuff varies widely in hardness and contains many hole and flaws, so it is tricky to make a decent gemstone. It is also hard to find bright orange. The pendant I made looks like an evil mask. The stone was so flashy it did not need a fancy wrap.

Keswick Agate

Keswick Agate

I cut a Keswick Agate from Keswick, Iowa, leaving quite a bit of ordinary Quartz on the side. This was intentional. I envisioned using some of my wire over the Quartz to really enhance the eye-like pattern of the Agate. A plain wrap, like I did on the Bumblebee, would not work with the Keswick. Keswick Agate is difficult to obtain and good Keswick is hard to find.

I wrapped a really fine faceted Aquamarine as well as another of Amethyst. I wrapped these so they can flip over while being worn.

Thomsonite of this quality is always popular.

Thomsonite of this quality is always popular.

The Keweenaw Peninsula and Grand Marais, Minnesota both supply the beautiful Ziolite, Thomsonite. Dark eyed Thomsonite from the north shore is the most coveted. I was just mindlessly looking around the AGTA (American Gem Trade Association) show and happened to glance down a side isle and spot a couple trays in the bottom of a display case. My eye immediately focused in on a Thompsonite. I could not believe such a gemstone would exist in a show full of common Diamonds, Rubies, and Sapphires. This one even has copper inclusions.

I asked the lady at the booth if I could look at the two trays. In a humorous manner she said, “Oh, you want to look in my junk box?” I for sure wanted to get at that “junkbox”, and found several other treasures as well as this Thomsonite.

When the dealer dropped and broke one of my Malachite slices, I immediately thought of earrings to go with the bullseye pendant.

When the dealer dropped and broke one of my Malachite slices, I immediately thought of earrings to go with the bullseye pendant.

I could not help but purchase a perfect slice of Bullseye Malachite. I dislike cutting this stuff, but put my mask and gloves on, and went to it. What a great Pendant I made from the cab. The earrings came from the second slice off the same rock, but the owner of the business dropped it on the floor at checkout, and the slab broke in half. He gave me the two pieces, so I used them. I hate wasting good material.

Snoopy?

Speaking of Malachite, I saw Snoopy in a piece. Cool stuff.

Watermelon Tourmaline

Watermelon Tourmaline

Not much bigger than a dime, two other fantastic little pendants of Watermelon Tourmaline and Montana Agate called me. I have seldom seen a small agate with such a fantastic natural picture. Watermelon Tourmaline is the most coveted breed of this gemstone. Good Tourmaline, like this one, are always popular, no matter the price.

Cardinal Candy: Another rare red Yellow Cat.

Yellow Cat Petrified wood is from remote regions of Utah, and was used by Tiffany back in the day. Yellow Cat is the brightest red of any petrified wood. It is really an amazing and scarce agate. I was very excited to see some at one of the Tucson Shows. The dealer told me people walked by his supply all day; not recognizing it for what it was. I am happy my mind is full of knowledge on many rare rocks.

You hardly ever see Blue Lace Agate Drusy.

You hardly ever see Blue Lace Agate Drusy.

Bonnie is especially fond of Blue Lace Agate. Imagine her thrill when I found some Blue Lace Drusy. Drusy means it contains pockets full of millions of tiny Quartz Crystals. This one I made into a designer cut beauty.

The workbench and the shop are still busy. I am so pleased with all the jewelry grade rocks I obtained out west, and am still exceedingly busy and thrilled about making a new crop of jewelry. I also enjoy sharing with you guys.

Nuumite/Nuummite-Jewelry from one of the Worlds OLDEST Stones

Today I wire-wrapped the oldest rock I have ever made jewelry from (I think). Nuumite is found a remote local near Nuuk, Greenland. It was discovered in 1982 and is of a metamorphic origin. Web sources claim that the site is accessible only by boat.

I bought this cabochon at the Tucson Shows years ago because of the sellers claim that it was “one of the oldest stones on Earth”. This is a claim you hear commonly in various locations. I hear it all the time in the Keweenaw Peninsula. So how old are the “oldest rocks on earth”? Sources claim Nuumite is in excess of 3 BILLION years old. The Swedish guy that sold me the Nuumite claimed it was 3.6 BILLION years old.

When oriented correctly the Nuumite shows and "Inner Gold".

When oriented correctly the Nuumite shows an"Inner Gold".

No glow is evident when the stone is turned.

No glow is evident when the stone is turned.

Nuumite resembles Labradorite because it sports an oriented Labradorescence that some call Schiller Effect. I believe the stone to be a Hornblende and when oriented correctly it flashes a golden color on one axis. This is described as “inner gold”. When turned the stone is simply black and shows no “flash” until it is oriented correctly similar to Labradorite. I would say that the effect is more of iridescence, and not exactly like Labradorite. Nuumite is not as flashy as Labradorite.

Nuumite will probably not compete as a great gemstone, but it certainly has an interesting story and it does have a neat golden-brown glimmer. Also, many metaphysical properties are contributed to this rock. This piece of jewelry should appeal to the Geology Expert as well.

It is unfortunate you cannot see the “inner Gold” to its’ true effect.

In this pendant I used both gold and silver which complements both the black and golden tones in the rock. This is an unusual stone, an unusual cut, and an unusual wire-wrap. Everything about Nuumite is special.

Amethyst Glitz

“Can you make me a pendant that will match this”? Of course I can, but why would Bonnie want another piece of jewelry when she has hundreds of pendants to choose from?

It all started on Black Friday (that was actually Thanksgiving Thursday this year). She had a coupon for a local Department Store. I’ll man up and admit that I saw a dressy coat that I thought would look nice on my bride. It had a great design and Amethyst colors. We both like Amethyst. Paired with a glimmering silver blouse, this jacket looked really great.

Unbeknown to me, the jewelry maker”s wife had NOTHING to wear with these garments, and this is where I come in. After I realized the wife has NO suitable jewelry, and asked me in a nice way to help out, I actually thought about making something like I’ve never done before. Here’s the dumb part: I announced on The Facebook I was going to make this pendant so my jewelry-less wife would have something to actually wear to our Rock club Christmas Party IN THREE DAYS!

Bonnie thought a white gemstone with some Amethyst beads that she rooted out of her beadroom stash, would look nice. We thought at first white druzy would work, but she settled on the wonderfully rare shiny white Victoria Stone. Argentium Sterling was the metal of choice. You can read the intriguing story about Victoria Stone in my blog at http://www.snobappealjewelry.com .

It took me a while to figure out what I wanted to make and more time figuring out HOW I was going to do it. After a good nap, I arose with my mind clear and a picture in my mind of what the pendant would look like. I usually do not use colored Aluminum wire, but Bonnie does with her beads. Alas, she did not have any purple (I thought she had every beading item available), so we made a not-so-quick-trip to craft stores (notice I said stores with an S) to locate this wire so I could continue.

After a few hours of watching various “Redneck” shows and wire wrapping, the pendant emerged from the workbench. A good hint is if you are using your mind creating jewelry, you can still watch mindless TV, but not anything deep like “Polar Bears Discuss How to Properly Prepare Seal Sushi”. 1. Wait for seal head to pop up in the hole. 2. Snatch seal from the hole and eat, no seasoning necessary.

OK, so I got off my point; deal with it. Maybe the reason that this piece of jewelry looks unlike anything I’ve done before is because of watching Redneck Duck Calls, or some such show while making it.

Since I was clearly focused on my task, Bonnie took this opportunity to vacuum, do laundry, make cookies, and in general stay clear of my area, and not interrupt my concentration. I do tend to get grumpy when interrupted at key points, and sometimes she can tell what’s key, and what isn’t.

I awoke this morning with ideas that came to me in dreams on how to finish this project. I got right on it even before coffee! The jewelry is actually finished ladies and gentlemen. I could go into a lot of details on how I pulled this one off, but it’s Christmas and the stores are open, and I have to set up for our Open House tomorrow. Remember, shop small or shop on this website (trust me, we’re small). Now enjoy, what Bonnie calls, “The glitziest pendant you’ve ever made”.

This cabochon had a big smile and little eyes. Lucy saw glasses on the face, as did I.

I thought about this face for a couple weeks and today an idea popped out. I saw the glasses and envisioned little curls.

This will make you smile.

Does this make you smile?

Here is the finished pendant. I hope it makes you smile as it does me. Lucy will really like this piece of jewelry in her collection and enjoy making other people smile.

Petoskey Stone Twins

Same stones; Different pendants.

Same stone; Different pendants.

Today I wrapped Petoskey Stone jewelry from a pair of cabochons of the same perfect stone.

The stone on the right was wrapped in Argentium Sterling and Pink Gold. The Pink Gold wire is a new product, so it is fun to try it out with different stones. This Petoskey stone really looks good in that combination, and result in a new jewelry look. This one is available for purchase today.

The next slab produced the stone on the left. I wrapped this one in 14/20 Gold Fill and Argentium. This one looks great also. This one will be for sale in Copper World in Calumet at the end of the week. You’ll have to call them!

I expect to make more Petoskey Stone Jewelry in the near future from some of the rare pick Petoskey’s I have, so watch for it.

Enjoy this pair; more to come.

Victoria Stone and Imperial Topaz-The Retirement Pendant

Sometimes making handcrafted jewelry requires a lot of thinking before any action is taken. I’ve been thinking about how technically to create this pendant for several weeks, and for various reasons all the pieces of the puzzle did not come together until now. What I see in my mind’s eye sometimes does not easily translate into a finished piece of jewelry. On rare occasions the process of how to make a pendant has to simmer inside of my head for a while.

I could not figure an easy way to create this piece of jewelry. I am showing you one of most complicated wire-wrap jobs I’ve ever accomplished. Alert: I would recommend you not attempt this at home!

This has been in holding since June 15th. I've got the stones, now what should I do?

This has been in holding since June 15th. I’ve got the stones, now what should I do?

I started with an impossibly rare bottom end piece from a Victoria Stone Boule. I previously mentioned in another blog about the unusual, chatoyant, flower pattern that appears on only the bottom of the Victoria Stone boule. (http://www.snobappealjewelry.com/blog/?p=159) Among Victoria Stones, this is the most unusual of patterns. I have been saving this particular Cabochon for several years, until I figured out something to do with it that was worthy of its’ beauty.

I had one of my “jewelry dreams” one night and thought that Imperial Topaz might work with this green Victoria Stone Cabochon.

Imperial Topaz is considered by most to be the Cadillac of Topaz, and quite expensive (so is the Victoria Stone). An opportunity to buy a large faceted Imperial Topaz presented itself last year, so I jumped at it. I liked this natural 28.9 ct Imperial Topaz from Pakistan because it has a large platelet inside. The platelet produces a rainbow within the stone. Unfortunately under the photo lights I use, you cannot see the phenomenon. You’d have to see this in person to really appreciate it.

What do you think of this one? BLING! BLING!

What do you think of this one? BLING! BLING!

Putting the Topaz and the Victoria Stone together was a match made in heaven, but not quite enough bling for old Don. I added two faceted Pink Topaz and a pair of lovely green Peridots. NOW there was something unbelievably nice!

Several hours of work over several days produced this amazing piece of jewelry.

I refer this piece of jewelry The Retirement Pendant because it is the pendant I have been planning ever since retiring from my day job a couple weeks ago! Bonnie wants me to give it a more fitting name when I post it on this site for sale in the next couple days. It’ll take me this long to figure out the perfect name, but if you have any suggestions I will consider them.

Enjoy this special piece.
