RARE, lustrous, golden-brown and dark chocolate-brown buergerite crystals are aesthetically set on quartz rhyolite matrix from the ONE-TIME FIND in Mexico. A rare example of this tourmaline varietal that was found once, in the 60's, by a miner who brought the lot to Tucson for sale. He died shortly thereafter and to my knowledge nobody has yet rediscovered his locality, an aberrant topaz-bearing rhyolite somewhere out in the desert in this region. In person, the crystals have a unique and characteristic golden sheen to them. RARE on the market today! This is a GOOD one from the collection of elite thumbnail collector, Allan Young, who has won the Desautels Trophy at Tucson with his thumbnails.
