Description & Provenance

The Pederneira Mine of Brazil is known for producing some of the most magnificent specimens of tourmaline ever recovered and is owned by our very own, Daniel Trinchillo. It was originally a mica mine, exploited for insulant material for the war effort during the 1940s & 1950s, but the 1970s and 1980s gave rise to increased recognition of tourmaline as a semi-precious gemstone and the early mine operators realized they had an incredible resource on their hands. Thusly, Pederneira was transformed into a tourmaline mine and was soon realized as one of the greatest sources of tourmaline worldwide.

This fine tourmaline is among the earlier specimens extracted from Pederneira by the mine operators during the first era of mining (circa 1985) from a pocket found in Dilo’s Tunnel (a delineation made for tourmalines extracted before 1999 at Pederneira). Given the timeline of mining, it was likely unearthed in the mid-1980s and is considered to be one of the finer specimens preserved from those early discoveries since much of the material produced in that time was cut into gems.

This fine specimen is a taste of the spectacular colors, and diversity of associated minerals produced by Pederneira. It is a green-blue tourmaline with a cranberry-fuchsia cap and core, the latter of which is partially embedded in a matrix of snow-white albite and dark, contrasting lepidolite. An elongated quartz crystal anchors the piece, adding to its visual and geological interest as a fourth complementary mineral. It has graced the famed Keith Proctor Collection, and was later acquired by collector, Wayne Sorenson.

Its success in the collecting world can be attributed to its associated minerals and its vivid colors, colors which happen to be among the favorite combinations produced by Pederneira. It exemplifies why tourmaline has skyrocketed in popularity among jewelers and collectors alike.
