Buergerite (rare tourmaline group member!) ex Krause Coll.

Item Description

A rare tourmaline group species. Lustrous, golden-brown and dark chocolate-brown buergerite crystals to 1.0 cm from the ONE-TIME FIND in Mexico. An excellent and 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 precise locality, an aberrant topaz-bearing rhyolite somewhere out in the desert in this region. Only a few have been recovered in all the time since. In person, the crystals have a unique and characteristic golden sheen to them. RARE on the market today! A very nifty, pristine plate with nice coverage. Valued $300-400. Ex Larry Krause Collection. MUCH BETTER IN PERSON!!
