A group of lustrous transparent golden compound crystals of barite on matrix. Displays wonderfully.
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 bi-colored naturally etched beryl crystal (pastel blue and pink) sits inside a pastel greyish cast of biotite crystals. Herb’s label says aquamarine, but I believe the center of the crystal runs towards pink morganite. One of the most unique specimens I have ever encountered. * For some reason I could not get blue color correctly on photos, they appear greener than they are, instead of blue.
A light pink,euhedral and complete crystal of the morganite variety of beryl with highly lustrous , well defined faces and glassy transparency sits on a muscovite matrix with minor albite, cookeite and cassiterite. Exceptional miniature from this world reknown locality and a find for those that collect beryls and/or gem crystals!
A group of translucent deep orange brown calcite stalactites on calcite and limestone. From what I have learned is that these are found in concretions and not caves.
