Red Gems

Red is one of the rarest colors in the gems world, and a pure red, such as the famed pigeon's blood ruby, is exceptionally rare. Most red gems are orangey-red (spinel), pink-red (spinel, garnet) or purplish-red (rubellite tourmaline).

Blue Gems

Though blue is a more common gem color than red, very few gems occur in a pure saturated blue. Sapphire is really the only example, though tanzanite sometimes comes close. Other blue gems tend to be a grayish-blue (spinel, benitoite), greenish-blue (blue zircon, apatite, tourmaline, gem silica) or a pastel blue (aquamarine, topaz).

Green Gems

Green presents the most choices in the gems world, but many of the finest green gems, such as emerald, jadeite, tsavorite garnet and demantoid garnet, are quite rare. Green hues are mainly due to traces of chromium and vanadium or iron.

Star and Cat's Eye Gems
