Calcite in Fossil Clam
stock #Alec 19-286
Rucks Pit, Fort Drum, Okeechobee
Florida, United States
9.4 x 8.8 x 5.7 (cabinet)
price: $290
Pre Holiday 2017

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.
Calcite- Classic form with minor Pyrite
stock #A-13-001
Shullsburg, Lafayette County
Wisconsin, United States
10.8 x 9 x 7.9 CM (cabinet)
price: $390
Pre Holiday 2017

This is a choice Shullsburg Calcite with the classic stepped Scalenenohedral crystals that have enlarged clear prismatic terminations. Far more transparent in person this has glassy luster and faint phantoms of internal Pyrite crystals. In excellent condition the only damage is the base and back lower edge area where this was removed. A choice older specimen, these are modern classics and this is like a textbook example of epitaxial alignment of prism faces.
