Giant Sea Fossil Necklace - C

$265.00 Regular price
Unit price


This amazing piece is known as a Simbircite. This was an ammonite but an agatized material filled in chambers of the Ammonite. It is a complex mix of iron & magnesium rich calcite, aragonite, pyrite, zeolite, and quartz. It has little thin veins of pyrite which were originally the bone of the ammonite. Formed over 160 million years ago, Simbircite with pyrite is both a gemstone and fossil. This stunning, high grade piece also has a huge spot of Ammolite on the right side of the stone - it has gorgeous red flashes of color because it is a natural opal-like material that is formed overtime from fossilized Ammonite shells. In direct light, it even flashes rainbow colors. 

The copper on this piece just goes around the edges, leaving most of the back exposed. This particular piece is backed with a different Simbricite material which is quite lovely, so you can see that as well - shown in last photo.

It is hard to photograph this piece because there are so many beautiful details - it is even much more gorgeous in person. 

The pendant is about 4 inches long, the chain is about 23 inches long.

How Its Made: Each stone is handpicked to meet my standards of excellent quality. Ring bands and many other connective parts are hand formed and are then sculpted onto the stone with a permanent epoxy. In the areas where I would like metal to be, I paint each piece with an electrically conductive paint. The next step is to put a removable, protective covering on all stones. The necklace will then go through a process where it is submerged into an acid bath and the areas with the conductive paint will begin to grow a super strong layer of 100% pure copper. This growth process takes 12 - 36 hours for each piece and is monitored during the process. After this is done, each piece is one by one hand polished, cleaned, oxidized, polished again, and then given a clear protective coating. After they are all dry and finished, they are ready to be added to high quality, beautiful chains :)
