2.0 x 1.5 x 1.0 cm. 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.
5.3 x 4 x 1.1 cm. This is a rich, aesthetic specimen of this very rare tourmaline varietal. It is not only attractive, but is moreover a rare example of this tourmaline varietal that was found once, in the 60's. This piece has a high lustre and amber/golden internal highlights to the crystals when hit with good lighting. Ex. Martin Zinn Collection.
This is a rare specimen on the market, as only a single lot of these Mexican buergerites arrived at the Tucson show years back from a new find, and then the person who mined them died without ever revealing the location they came from – so that was likely all there will ever be. The abundant crystals, to 1.2 cm, are brown with an iridescent golden sheen characteistic of this tourmaline species. 5.3 x 3.7 x 2.5 cm
1.5 x 1.0 x 1.0 cm. A rare, lustrous, doubly terminated, golden-brown and dark chocolate-brown buergerite crystal from the one-time fine in Mexico. A rare example of this tourmaline varietal that was found once, in the 1960s, 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. This rarity is complete-all-around and nearly pristine.
4.2 x 3.2 x 1.3 cm. A rare tourmaline group species - rare, lustrous, golden-brown and dark chocolate-brown buergerite crystals to 1.2 cm from the famous find in Mexico. A rich and rare example of this tourmaline varietal that was found in the 1960's, by a miner who brought the lot to Tucson for sale. In person, the crystals have a unique and characteristic golden sheen to them. Rarely available today. A very interesting, pristine plate with rich coverage.
A showy, aesthetic and RARE specimen of lustrous rich chocolate-brown buergerite crystals to 1.5 cm on 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. 4.4 x 3.7 x 2.2 cm
15 x 12 x 4 cm. Buergerite is a rare member of the tourmaline group recognized superficially by its brown color with golden internal flecks, found nowhere else in good crystals. The locality produced one single batch in the late 1960s, which came to Tucson. The person who found it died before revealing the location; and no more was found until Dr. Romero hired two exploration geologists to go looking for it again. Few were found, and Romero kept the best small and large specimens in his collection. This was the larger of his two specimens, and should be considered likely to be the best large plate of this material out there. This specimen from the Dr Miguel Romero collection was on loan exhibition to the University of Arizona Museum for over a decade, until my purchase of this collection in 2008. It was on display in special cases at the museum, and has since been featured in the book "The Miguel Romero Collection of Mexico Minerals" which we sponsored as a special supplement book (published by the Mineralogical Record in December of 2008).
RARE, lustrous, chocolate-brown buergerite crystals to 8 mm aesthetically scattered as isolated single crystals or in groups, 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. 6.8 x 6.6 x 2.8 cm

This rich, aesthetic piece is the best example I have ever seen for sale of this very rare tourmaline varietal. It is not only attractive, but is moreover 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 (thought to be a topaz-bearing rhyolite pod). The best of these, as with this one, have high lustre and amber/golden internal highlights to the crystals when hit with good lighting.

A fairly rare member of the tourmaline group, this specimen on matrix is composed of several, doubly terminated, prismatic crystals of lustrous, bronze colored crystals to 1 cm in length. Notice the fascinating golden sheen effect o the surface. From the type locality at Mexquitic, San Luis Potosi, Mexico. Although this is a thumbnail, it is easily the most aesthetic buergerite I have ever seen. Undamaged and wonderful, the eye appeal is beyond belief for this normally homely species. It is actually competition- grade, for a species which normally is relegated to "intellectual" status only. Few were found, and the exact locality is now lost. This piece comes from an old collection being sold off, as do most. Joe Budd photo
