Garnet is a gemstone most known to be red, but in fact it is found in a variety of colors. The six types of Garnet—Rhodolite, Almandine, Spessartine, Grossular, Andradite and Uvarovite—have different colors. The word Garnet is derived from the Latin word granatum, which meant “pomegranate” a reference to the stone’s similarity in form and color to a pomegranate seed.

Their hardness varies from 6.5 to 7.5. Garnet is not a single mineral, but a group contains closely related, isomorphous minerals that form a series with each other. Their crystal systems can be isometric, rhombic, dodecahedron and/or icositetrahedron. The Garnet members form intermediary minerals between each member and may even intergrow within a single crystal. The Garnets vary only slightly in physical properties, and some of the members may be so similar that they are indistinguishable from one another without x-ray analysis. Most, but not all Garnets are varieties of aluminum silicates.

The common Garnets can be divided into two subgroups:
Group 1: Garnets containing aluminum (Al) as their second element.
These include Pyrope, Almandine, and Spessartine. ("Pyralspite")

Group 2: Garnets containing calcium (Ca) as their first element. 
These include Uvarovite, Grossular, and Andradite. ("Ugrandite")
