A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.

This is a very nice specimen of the beige scheelite and muscovite from the top local of this species.
Nice piece from the famous scheelite mine in China.
This is one of the very nice scheelite specimens from the top local of this species.
This Scheelite crystal thumbnail is in great condition and literally has an entire back side covered in Muscovite.
The most common Smithsonite found is the colored boytroydal structure. This specimen, however, actually is the full clear crystal structure.
This is a very interesting piece. These are multiple double terminated Smokey Amethyst crystals grown tip to tip into a Scepter-like cluster.
This Smokey Quartz cluster is a nice deep gray/brown color with Garnet crystals around the base.
This Smokey point has some point damage, very minor on the main crystal and a bit more noticeable on the backside secondary crystal.
This is an incredible combination of minerals. Very nice presentation with some micro damage only.
