A far better than average specimen of the remarkable Calcite in Clam shell fossil from the renowned Rucks pit. This was once a prolific small quarry and produced many of the Miocence age fossil Clams. Now closed to collecting and reportedly exhausted, this was a unique deposit. This example is a perfectly complete shell, well defined and showing the Clam exterior replaced by tiny Calcite crystals. The inner void is seen through an opening at the hinge and shows well formed gemmy amber color Calcite prisms to 3.1 CM long lining the inside. These were plentiful in the past, but fine, perfect examples like this were never common and are now especially desirable and rare.
An exceptional specimen the most perfect, colorful and gemmy Calcite I have seen from the closed Rucks Pit fossil clam locality. From early finds at this now classic location, an ex Arkenstone specimen, the luster and transparency are hard to capture in a photo. A small amount of the original clamshell fossil forms the base of this piece, the crystals had grown inside the clam but are now exposed. Unlike most of the thousands of specimens from here this is in the top .001 percent!
