Highly lustrous, pastel blue-grey blades of barite on a matrix of yellow fluorite crystals. Aesthetic miniature!
Orange prisms of orpiment are intermixed with tabular pastel blue barite blades.
A beautiful amber group of translucent bastnasite (Ce) crystals sits on a matrix of quartz crystals and acicular green titanite crystals that are also inclusions in the quartz. Fairly rare cerium member of the species.
During the summer of 2012, a small lot of the deep blue aquas appeared on the market and were thought to be Vorobyevite. After analysis by Dr. Federico Pezzotta in Milan, they were confirmed to be a cesium included beryl, but not rich enough to be vorobyevite. Most of the crystals found were under 2.5 cm wide, so this one would be in the top percent for quality color and crystal size (3.4 cm!). No more have been found.
A group of intergrown crystals of red beryl on a matrix of white rhyolite. A smaller single crystal sits to the right of the group.
Sharp crystals of bournonite on equally sharp golden pyrites and sphalerites.
Deep forest green acicular crystals of brochantite associated with crystallized azurite. Ex Arizona dealer (and field collector) Dick Jones label which means it was obtained prior to 1982.
A curved “stalactite” of calcite with minor malachite on some of the surface. classic Bisbee.
