Copper World-A Special Appearance

Everyones favorite gift shop.

Everyones favorite gift shop.

I will be making jewelry in Calumet Friday evening, July 5th (First Friday gala in Calumet), and all day July 6th. I’ll be so happy to be back in the U.P. and to visit all my friends and fans old and new.

I will be making jewelry from local rocks, minerals, and gemstones (most found by myself and Bonnie). I can also make something for you from my stones or yours. See you soon.

Happy 4th of July and God Bless America

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 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.

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.

Pink Petoskey Stone (Pink Pets)

Pink Petoskey Stones from Northern Michigan” is the title of a feature article in the May/June edition of Rocks and Minerals Magazine written by Dr. George Robinson with me as coauthor. George is past Director and retired Curator of the A.E. Seaman Mineral Museum at Michigan Tech in Houghton, Michigan. The Museum is the official State Mineral Museum of Michigan and boasts the finest collection of minerals from the Copper Country in the world.

Pink Petoskey Stones get no better than this one. I could not in good conscious keep it for myself, so I donated it to the A.E.Seaman Mineral Museum.  You can see it in the Petoskey Stone/Michigan Fossil Case.

If you search the Seaman Museum, you will see a very fine Pink Petoskey Stone that I found, polished, and donated.

When you read the article in Rocks and Minerals, you will find the cause of the pink coloration is Iron that permeated into the Hexagonaria Coral as it Calcified. People have asked me if Petoskey Stone is the only Devonian Fossil that shows saturation of iron, and the answer is no.

Any Devonian Fossil can show evidence of iron deposition. I have seen pink hues in Horn Coral, Favosites, and even Clams from this period.

Since Dr. Robinson has researched the cause of the pink in Petoskey Stones (and these other Devonian Fossils), I will not expand on that in this article. Rather I would concentrate on helping you find some of these rare beauties.

The high quality Petoskey Stones that I find are concentrated in NW lower Michigan in glacial tills and on the beaches of Lake Michigan. I have found the Petoskey Stones on the east side of Michigan are not generally of the quality I find on the west side. These east side stones tend to be porous and will not take the high polish that a more solid stone will take. Quality Jewelry and nice specimens require solid stones. Don’t get me wrong, some nice stones have been found on the east side, but I’m happy I spend my time hunting on the west side.

Hunting in an old gravel pit or small stream may produce some nice Pink Petoskey Stones. Most people hunt the shorleline, but there are other areas to find Pink Pets.

A good stone is solid with a clear pattern (not muddy). This is what I look for. It is hard to find a Pink Petoskey without flaws (pits, holes, and the like). I believe somehow the Iron Oxide in the Calcite is a causation in the weakening of the structure of these rare stones. In addition, there is never any guarantee as to how far into a stone the pink coloration permeates. It could be surface color or just as easily be throughout the stone. We do not know how deep the pink goes in a stone unless it is cut.

Most of you know that the Petoskey Stone is Michigan’s State Stone. Hexagonaria Corals are not strictly concentrated in Michigan, but indeed are found around the world. The finest Petoskey Corals are found in Michigan.

How can you find a Pink Pet? Over many years of hunting I have discovered that perhaps one out of 300 Petoskey Stones may display some pink. The pink hue can permiate thoughout the stone, or may be only skin deep. Rockhounds should stay alert for Petoskey Stone with a pink hue, instead of just looking for the common greys associated with the calcified Petoskey Stone.

The grey color of Petoskey Stones can vary. The difference between the light colored and the dark colored Petoskey is the level of petroleum in the stone. When I polish a darker stone I can actually smell a distinct odor of petroleum. Darker stones, because of their petrolem content, tend to take a higher shine than their light colored brothers. When iron is deposited with the calcified Petoskey the colorations very with light stones showing classic pink in the patterns and dark stones becoming almost a mahogany color.

You can see the difference between the dark pink and the light pink in these pendants I made.

Where do you look for rare Pink Pets after you telling yourself to think pink? I am not going to give up my secret spots of course, but I will say that I find many on the gravel back roads on a rainy day. Petoskey Stones are elusive when dry, but “pop” when wet. Any rainy day, we are out looking. Property owners in NW Michigan are very protective (and have weapons), so do not trespass. Private property includes many gravel pits as well. So get permission before hunting. You are not trespassing if you are hunting rocks on the public roads, but of course, use caution while hunting. Road cuts are another place not to pass up in your search. Utility poles generally designate the road right of way in Michigan, so if you are inside the utility poles, you are probably on public property. You will want a container to put your treasures into, and my favorite is a large ice cream bucket.

There's got to be a Petoskey Stone around here!

Beaches, as well as back roads, produce Petoskey Stones. I am surprised by the novice Petoskey Hunters that think they have to go to the Petoskey area to find Petoskey Stones. Anywhere from Manistee to I75 and north is prime hunting for quality Petoskey Stones but Manistee east to Alpena and north is good hunting. The Straights of Macinaw seems to be the end of good Petoskey Stone hunting as flat broken rocks inhabit the shoreline.

When enjoying northern Michigan, and the weather turns wet, make lemonade out of lemons and go for a wet hike on the beach, along a roadway, or a roadcut and look for that rare pink Petoskey Stone.
