- Bertrandite with Tourmaline
- Small Cabinet, 6.8 x 4.1 x 3.0 cm
- Golconda Mine, Governador Valadares, Minas Gerais, Brazil
An astonishing and unusual pegmatite combination piece of bertrandite and tourmaline var. schorl. The bertrandite crystals, to 3.5 cm in length, are tabular, pearlescent and translucent, and exhibit a snow-white color. The schorl crystal, measuring 4 cm in length, is slightly curved (a weird effect you see in some tourmalines due to unusual geology as it forms) and its termination is actually a very rare style composed of hair-like filaments of tourmaline that grow along their long axis but somehow never annealed along the horizontal axes, to form a solid termination in the normal sense. It IS terminated, but with what seems a head of hair. 360 degrees and complete all around, this is a display quality specimen of bertrandite with flair. It is something completely unprecedented based on previous finds of the species, from here (or anywhere for that matter).
