Lazulite Oval Cabochon Pendant. Graves Mountain, Lincoln Co., Georgia, USA. 14K Gold. 16 mm x 12 mm. 7 ct.
This is the best color cabochon that I had, so I had it set in 14K gold.
Lazulite is a very rare magnesium phosphate, and Graves Mountain is the premier locality for the opaque bi-pyramidal twinned crystals, and the only occurrence where the crystals are large enough to cut into gemstones. The deposit no longer produces the larger crystals, but the matrix material is still occasionally found.
Lazulite is sometimes confused with 2 better known and more common minerals: lazurite and azurite. Lazulite frequently appears as euhedral crystals rather than in massive form.
Mohs Hardness 5.5
Specific Gravity 3.04 to 3.17
