This is a very impressive specimen from Stak Nala, the most famous Tourmaline locality in Pakistan. This crystal features several colors ranging from a deep forest green to a beautiful grass green termination, there is a nice rosette of bladed Albite crystals sitting aesthetically on the side of the specimen. The termination is excellent, and has the trigonal ‘Mercedes’ pattern famously seen on the Erongo Schorls. The prism of the Tourmaline is exceptionally lustrous for this material, with good striations. What really makes it for me, though, is the grass green zone near the termination, The contrast is beautiful, and the very sharp, dark green banding in the main crystal and the sidecars are aesthetic knockouts! This is a great display piece and a wonderful pegmatite specimen from a classic locality.
Description
Detailed Description
A beautiful deep green elbaite tourmaline crystals, flanked by albite crystals. The tourmalines are dark, with a more moderate green colour at their terminations, best visible with strong light. The piece perfectly for display. In excellent condition, no damage to the singly-terminated tourmaline crystals. Great aesthetics, with these slightly divergent tourmalines!
About These Stak Nala Tourmalines
Since the 1980s, elbaite toumaline crystals from the pegmatites at Stak Nala have been known worldwide. Particularly distinctive and prized when associated with albite crystals, these tourmalines are usually colour-zoned, with dark green to black-appearing centre sections, with zones of green, pink, blue or colourless zones at the terminations – often, a closer inspection with strong light or a strong reflective background are needed to show these zones. The doubly-terminated crystals from Stak Nala are super examples of hemimorphism (the crystal forms present at one termination are different from those at the other termination). I was fortunate to acquire these from a member of the family that mines them.
