Agatized Coral (AC3)
Notes specific to this specimen: This is an exceptional and exquisite carnelian agate pair with rare fortified agatized cavities and preserved microscopic internal structures. This cut and polished pair is mounted on a pleasing piece of Suwanee Limestone – which is the matrix material these specimens originated from. No other preparator mounts these specimens on their native matrix. Honestly, most people don’t even know how they formed, much less know the association with Suwanee Limestone! You can see how translucent the hollows are – the carnelian agate just glows! Zoom in and look at the lighter colored sections below the hollow and you’ll see that it’s actually lace agate. We’ve never seen this before This is a one-of-a-kind beautiful pair!

Crystalized Welks (W2)
Notes specific to this specimen: Fossil welks are much rarer than the clams found at Rucks Pit and most of them have no crystals. But, when you do find a nice crystal-line specimen, there’s nothing like it in the world! This is a single welk with a natural opening on its dorsal (top) allowing you to see the crystal lining of the shell and the gray sparite “floor” that was the sediment which partially filled the shell after the animal had died. Very unusual.
