a beautiful honey yellow starburst
These calcites from Florida grow in fossil clam shells, you can see the remains of the clam shell on the back (photo 3&4) and provides a very nice contrast to the honey yellow calcite
The fossil clam is Mercenaria permagna - late Pliocene
The now closed location is Rucks Pit, Okeechobee Co., Florida

2 inches x 1 inch x .5 inches
22 grams
Perfect for wire wrapping, but be careful. Calcite is soft and you will need not to exert too much pressure while working. The matrix could probably be nipped off with needle nose pliers.

We prefer natural gemstones and only rarely sell enhanced gemstones. If the stone is enhanced we clearly state the enhancement in the listing ad.

I do my best to describe all items accurately and will point out notable defects and flaws, however, due to the nature of natural stones I may miss minute flaws. Please do not hesitate to ask

Some gemstones prefer not to be constantly exposed to direct sunlight, please ask.

Please ask about cleaning instructions. Different minerals require different care. Please never plunge a crystal into very hot or very cold water, the sudden temperature change can be damaging
