This is a unique specimen with parallel growth crystalization, and two tiers of termination faces. The focal point is the great pair of terminations at the apex. Stands perfectly for display as in the photograph.
About These Dravite Tourmalines
These dravite tourmalines from Serra Branca, Brazil, are sharp crystals!
All of the crystals are doubly-terminated. The prism faces have a bright lustre, like black opaque glass. Under bright lights (such as the photography lighting), a few subsurface glints of internal brown are visible in some, but under normal lighting, to the eye the crystals look essentially black and opaque. The termination faces vary, with many showing a slightly silky lustre and delicate texture. Most of these are crisp, simple crystals (they really look like idealized crystal models!) and some have a bit more complexity to them. None of these crystals are perfect all-around – they have a little edge wear or minor nicking in some place or another – however, these are high quality specimens and they are the best of the lot.
