Merelani Hills, Arusha, Tanzania
8mm x 5mm x 4mm
$350
Single blue Tanzanite crystal with micro hair-like inclusions of Merelaniite. The Tanzanite is complete all around, glassy, and transparent. Merelaniite is a recently discovered rare mineral in the Cylindrite group of minerals. These are rare enough just attached to other minerals, but even more so when included within a complete Tanzanite crystal! Ex. Jon Sigerman.
