Quartz (Var: Smoky Quartz), Quartz (Var: Amethyst)
Comments
Description
This big Montana smoky quartz has a fascinating termination. Part of the termination is typical smoky quartz; but about half-way over, it bevels out slightly into amethyst, which forms three of the six faces of the termination. This amethyst appears to be an overgrowth of complete smoky faces underneath, a sort of "cap" over half the termination. Ex. Richard Hauck Collection.
