5 Lazulite Cabochons. Graves Mountain, Lincoln Co., Georgia, USA. 18 mm x 13 mm. 64 ct. total weight.
An interesting stone for a jewelry project, 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.
These are all cut from single crystals found back in the 1990’s, and vary from denim blue to midnight blue.
