Photographing highly translucent minerals can be tricky. Under studio lighting it's difficult to capture the exact colour of the gemstone. Describing this green fluorite cabochon as having a minty green colour is pretty accurate.
Fluorite occurs in many different colours and when several colours are present together in layers or zones, it's often known as rainbow fluorite.
This green fluorite pendant has been reduced because there's is a natural flaw in the bottom section of the crystal. This seems to have been caused by a surface reaching fissure. It can seen in our second photograph but can hardly be felt. When the pendant is being it really can't be seen.
Should you not be completely satisfied with this green fluorite pendant it may be returned for a full refund (T&C's apply).
