Dravite Tourmaline

Specimen # 100172
Mineral: Dravite Tourmaline From Brazil
Location: Serra Branca, Rio Grande do Norte, Brazil
Size: 3.9 x 1.8 x 1.5 cm


Detailed Description

This is an exquisite dravite for this find. It is as good as these get! Sharp clean crystal faces, bright lustre – even the top termination is bright and lustrous. The top terminatinon is striking because the three faces are so nearly equal. There is a chip at one back termination corner, but displayed properly it is out of view, not distracting. This crystal almost looks machined (don’t worry, it’s not) – really it looks like a crystal model cut from from opaque black glass. Stands perfectly.  So cool.

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.

These specimens were collected in the 1990s and they were squirrelled away in Brazil. Frank Melanson had analysis done to confirm that they should be labeled dravite.
