I will be listing many new, high grade Russian Amonites and Simbricite cabochons with pyrite druzy in them. These were professionally cut and polished for me by Russian miners/lapidary artists form Ural. You will not find such material here on Etsy or anywhere else, because Ammonite with Simbricite (the orange translucent part) in this quality is very rare. Each stone has a high gloss, a mirror like, polish on top, and a nice polish on the back or is backed up with polished black granite. I will have a huge collection - each fossil is unique and absolutely gorgeous. They are around 80 millions years old - an echo of eternity!
<<<<<<I think this is one of my most beautiful ammonites! It has a large cavity in the middle covered with fine pyrite druzy and surrounded with very pronounced pyrite veins. Incredibly sparkly and just gorgeous! It has a simbircite body - dark chocolate color. The fossil is cut in a modern geometric shape. Polished to a high gloss mirror like finish. Great stone for your unique designs!>>>>>>
The size of this cab is 63x44x9mm
About the material: "AMMONITES REPLACED BY PRYITE! FROM THE VOLGA RIVER AREA, SARATOV, RUSSIA. ABOUT 150 MYA, DURING THE JURASSIC PERIOD, THESE AMMONITES DIED IN A SEA THAT CONTAINED A HEAVY CONCENTRATION OF IRON. THIS IRON REACTED WITH SULFUR IN THE WATER AND FORMED THE IRON PRYITE WHICH REPLACED THE AMMONITE CELL BY CELL. THE OUTER SHELL SOMETIMES REMAINED BUT THE CHAMBERS WERE REPLACED WITH PYRITE" (c)
