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.

The aquamarine sits very nicely in this piece. Surrounded by the black tourmaline. It is a very aesthetic piece.
There are light blue aquamarines over much of this schorl.
Very nice piece that displays nicely. The three crystals set each other off very nicely.
This is a very nice specimen where the Apophyllite and Heulandite have grown on Calcite, almost like a stalactite.
