MK915 - McGuinnessite Red Mountain, Mendocino Co., California, USA small cabinet - 8 x 6 x 4.5 cm Blue/green McGuinnessite on multiple sides of a rock matrix. Mcguinnessite is a rare Mg-Cu carbonate, a member of Rosasite Group and is named after well-known California mineralogist, Al McGuinness. The matrix is richly covered with radial clusters and hemispheres of teal-blue McGuinnessite on most sides. Comes with an old Chuck Trantham label that indicates it was collected in July 1975. Comes with an old Al McGuinness label. Ex. Len Pisciotta collection.
MK840 - Andradite near Bishop, Inyo Co., California, USA small cabinet - 5.8 x 3.5 x 2 cm Cluster of highly lustrous orange/brown Andradite crystals on matrix. Individual crystals reach 1.7cm wide.
LP149 - Quartz, Epidote after Andradite Garnet Hill Mine, Calaveras Co., California, USA small cabinet - 7.5 x 4 x 3.5 cm Rare pseudomorph of white Quartz and green Epidote that has replaced a large Andradite garnet crystal. The main crystal is 5cm in size and shows areas of white Quartz and pistacio green Epidote. The repalcement is complete with virtually no Andradite remaining. Ex. Len Pisciotta collection. Len collected this locality often and this was one of his 'keepers'.
MK837 - Topaz Maynard (Bixby) Mine, Thomas Range, Juab Co., Utah, USA miniature - 3.7 x 3 x 3 cm Well balanced specimen of Topaz crystals on Rhyolite matrix. The Topaz are gemmy and undamaged. There are small crystals rising up around the bottom with a larger 3.2cm crystal crossing over the top.
LP445 - Quartz Gwindel Shalman, Khyber Agency, Pakistan small cabinet - 7 x 5 x 4 cm Transparent Quartz gwindel, 5.5cm wide, with Quartz crystals of typical form. Complete all around and in excellent condition. Ex. Len Pisciotta collection. I like the combination of the two forms of Quartz together.
LP447 - Quartz Gwindel Shalman, Khyber Agency, Pakistan small cabinet - 5.5 x 3.7 x 2.4 cm Glassy single Quartz gwindel from Pakistan. Complete all around and nearly pristine. Ex. Len Pisciotta collection.
LP590 - Ludlamite with Vivianite Cabeca do Cachorro claim, Sao Gabriel da Cachoeira, Amazonas, Brazil cabinet - 14 x 13 x 4 cm Glassy bright green Ludlamite crystals and bluegreen Vivianite on matrix from a relatively new locality in northwestern Brazil. The crystals are bright, translucent to transparent, and reach 1.5cm in size. Gorgeous specimen of exceptional quality for the species.
LP611 - Malachite on Dioptase with Shattuckite pseudomorphs Tantara Mine, Shinkolobwe, Katanga, DR Congo cabinet - 10.5 x 7 x 6 cm Large specimen of Dioptase, primary Malachite crystals, and Shattuckite. Though not a classically perfect specimen (the front of the Malachite cluster is contacted by the opposing pocket wall), it is none the less large, impressive, and very interesting. Also, I got it in trade and have it priced to move. To start with, the cluster of Malachite crystals is nearly 6cm wide and composed of huge individual crysals that are sharp and pointed. There is no rock matrix - the rest of the specimen is composed entirely of Dioptase crystals, Shattuckite, and Chrysocolla. On the right side there is a large open vug lined with botryoidal Shattuckite and Dioptase crystals. On the back, there are at least a few small crystals of the rare double pseudomorph of Shattuckite after Dioptase after Calcite. All in all, a highly interesting and representative specimen from the Tantara Mine.

Whereas most Milpillas Cuprite are more flat lying on matrix, this specimen features robust crystals that rise up off the matrix. Individual crystals reach 1.4cm in size and are highly translucent to transparent when backlit.
AU684 - Natrolite Mwanjanga, Manyara Region, Tanzania small cabinet - 7.7 x 0.5 x 0.4 cm Long translucent to transparent single Natrolite crystal. Perfectly terminated and complete and undamaged. From recent, limited production, these new Natrolites are exceptional for the species for their sharpness and transparency.
