Outstanding Butte Enargite with large isolated crystals to 1.6 cm. Choice, quality crystals with accenting small Quartz crystals.

A 1.2cm cube of Byxbyite well centered in Rhyolite. Surrounding the cube are crystals of Topaz, purple Fluorite, and black acicular crystals of Pseudobrookite. Acquired by Mike Groben in 1980 and pictured in the August 1980 issue of the Lapidary Journal. Appraised years ago at $1500. Great display specimen and a good combination specimen of most of the important minerals found in this area. He's a chance to own a species that is normally black and somewhat non-exciting to look at in a vibrant specimen with color and aesthetics.

Two spherical clusters of Variscite crystals in a vug in Quartz. I obtained this specimen from dealer Steve Perry about 20 years ago during a visit to his home following one of his many trips to Brazil. This was the best of his specimens, with better color and sparkle than the rest. Variscite is usally found in massive form, rarely as crystals.

Great color and large crystals, this is one of the finest specimens from a large lot of recently mined and purchased Prehnite specimens from the Merelani Tanzanite mines. The main rosette is 4cm tall and sits nearly vertically for display. The larger crystals appear to have grown from a central sphere of Prehnite. The bottom is somewhat flat where it grew against Graphite. It's pristine except for light chipping on some crystals and a contacted backside.
