It's new find from Inner Mongolia! The Stepped cubic Green Fluorite crystal has blue/purple Center.
There are three kinds of interesting form:
A, The Fluorite crystals are aftering by a kind of white minerals - it looks the white mineral is growing like frost flower inside of the Fluorite crystal (as the #1 photo).
B, Part of the Fluorite crystals was aftered by white minerals (as #2 photo).
C, The Fluorite crystals were totally aftered by white minerals. So some Fluorite pseudomorph are cubic (as #3 photo), some are octahedron (as #4 photo).
