TOURMALINE GEMSTONES

Tourmaline is one of the most colorful members of the gemstone family, sometimes with alternating colors in the same gem.  The most common colors are pinks, reds (rubellite) and greens (verdite) however blues (indicolite) and other shades are extremely popular.  Tourmaline is a very good wearing gemstone with a hardness of 7 to 7.5 on the mohs scale.  The refractive index is 1.62 to 1.68 and the crystal system is trigonal.  More information on the history and lore of tourmaline is here.The majority of our tourmaline gemstones are mined in Brazil and Africa. Tourmaline crystal slices, rubellite (red), paraiba and watermelon (bi-color) tourmaline have links to their separate pages at the bottom of this page.
