TOURMALINE - O'Grady Lake area, Sapper Ranges, Northwest Territories

CRYSTAL SLICES

Gem quality tourmaline was discovered in 1994, near O’Grady Lake, about 110 kilometers north-northwest of the town of Tungsten, Northwest Territories. Translucent to transparent elbaite (tourmaline) occurs in crystal-lined cavities in granitic pegmatite. Crystals are typically colour zoned. Most common are crystals with pink and brownish-pink outer rims and black cores. Other colours include olive-green, orange-brown, and blue. Pinkish crystals range in size to 9.5 cm long. Transparent areas suitable for faceting occur between veils and fractures in some crystals. Other mineral species to yield faceted stones from this remote locality include danburite and smoky quartz.

The gems offered for sale on this page are cut and polished crystal slices. A tourmaline crystal is sliced perpendicular to its long axis into slabs about 2-3 mm thick. The slab is polished on both sides and the outer edges are left natural wherever possible and polished everywhere else. These gems were collected and cut by Brad, the owner of Alpine Gems.
