Thumbnail, 2.6 x 1.5 x 1.2 cm
Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania
A sharp, competition-quality thumbnail, gemmier and brighter in person. Here we have SUPER-GEMMY crystals of this rock-forming mineral that is normally dull and lifeless as far as crystals go. This locality has produced the best of species, from the collectors' point of view, and this is a good example why we say that. 2.6 x 1.5 x 1.2 cm
