Anapaite in fossil mollusc

Item Description

A really cute thumbnail. Lustrous, translucent, pretty light apple-green, pod-like aggregates of anapaite crystals and nubby spherical aggegates of ironstone rest in an upright fossilized mollusc shell from the Ukraine. This locality is now mined through and specimens are hard to obtain. Anapaite, a phosphate, is found in lacustrine (lake) sediments. A very fine thumbnail example.
