Display by Color
Gemstones have distinct colors, but most occur in more than one color. In this method, every possible color range of each gemstone is displayed based on the selection of the color chosen.

Display by Crystal Group
There are seven crystal systems that gemstones may belong to. They are: Hexagonal, Isometric, Monoclinic, Orthorhombic, Tetragonal, Triclinic, and Trigonal. (In the gemstone section, the hexagonal and trigonal crystal systems are treated as one group.) In this display method, gemstones are displayed by the crystal system they belong to. Amorphous gemstones (gemstones that do not belong to a crystal system) are also displayed through this method.
