4.3 x 2.7 x 2.1 cm. An exquisite Eastern European mini featuring a sharp, diamond-shaped quartz crystal that has been pseudomorphed by sandy quartz. At its base are more of these quartz crystals on a smaller scale, along with a translucent chisel-terminated calcite.
5.8 x 4.9 x 2.5 cm. Deep coffee-colored crystals of sphalerite, to over one centimeter, with flashy, lustrous faces - with little cream-colored calcites. From the well-known California collection of Charles Hansen.
10.4 x 6.4 x 5.4 cm. Two complex octahedrons of fluorite to 3.5 cm on edge, with thousands of surface microfaces, on a coated, euhedral crystal of quartz. The fluorites are green, with highlights of purple. Rare material from an abandoned Soviet-era military-run tungsten mine!
11.4 x 8.9 x 6.4 cm. The Little Three Mine in California has a special place in the heart of many collectors. This is a large combo specimen, with two lustrous, transparent smoky quartz crystals and books of shiny muscovite, intergrown with albite. There is a small, bright orange gemmy spessartine you can see sitting on one of the muscovites. Ex. Chris Korpi San Deigo collection.
3.7 x 2.8 x 2.4 cm. A magnificent small mini of an American classic, mined by Richard Kosnar on his claim in 1976. Several intergrown crystals of an intense turquoise color, with two transparent smokies. From the well-known California collection of Charles Hansen.
7.8 x 3.4 x 3.1 cm. Gorgeous! Rosettes of light pink, platy rhodochrosite crystals have grown on the tips of quartz crystals rising from a sulfide matrix. NOT your "typical" or common Chinese material! From the well-known California collection of Charles Hansen.
6.2 x 3.3 x 3.2 cm. Now here is a really unusual rarity: sharp, lustrous crystals of azurite that have grown on the tips of quartz crystals of a light blue color from a thin coating of a copper-rich mineral. These days, crystallized azurite specimens of any kind from Mexico have gotten hard to obtain, and this is a really special specimen. From the well-known California collection of Charles Hansen.
12.4 x 11.9 x 9.2 cm. A large and stunning amethyst specimen from South Africa, out of the collection of Dave Stoudt. It features two generations of crystals, a later generation of smaller ones wrapping the original, larger ones. In the center of the specimen is a 12 cm crystal that is completely covered in the sparkly points. Smaller ones shoot off in various directions around the base, with their gemmy terminations sticking out. The iron oxide inclusions add an orangey tone that makes it even prettier. Extremely aesthetic in every way and a superior piece from the find. Ex. Stoudt collection.
8.9 x 7.9 x 4.7 cm. On the outside, this section of the petrified tree still looks like wood (though now all replaced by quartz). The inside is replaced by dense brown quartz, which has been polished on one end. From the collection of Dave Stoudt.
6.9 x 4.3 x 2.9 cm. These two crossed crystals of smoky quartz, both complete and terminated on top, are wrapped completely in a blanket of gemmy, red-orange, super-lustrous spessartine garnets - with their terminations showing above them.
9.2 x 4.2 x 2.3 cm. This is a sharp, transparent quartz crystal in great condition (a couple of minor contacts) that is shot through with hair-like crystals of rutile - which you can clearly see due to the extreme clarity of the quartz. Under good light, these rutile crystals gleam like steel needles!
3.4 x 2.9 x 2.6 cm. A Brazilian cluster of the most prized variety of quartz, consisting of intergrown compound crystals that have formed three "fingers". There is no matrix here - the whole specimen is rose quartz.
5.5 x 5.1 x 4.1 cm. A 1.6-cm, dark red crystal of cinnabar, complete and undamaged, is isolated on the matrix and set off by a row of milky quartz crystals that lean in various directions at the back of the matrix.
27.8 x 14.4 x 6.5 cm. This is a monster specimen of the famous "water-clear" fluorite mined in the early 1980s at Dalnegorsk. The surface of the specimen is completely covered by hundreds of these clear fluorite cubes (maybe 200?). They are accented by little bursts of tan-colored quartz. The fluorites measure to 1.5 cm, though most are smaller. THERE IS ALMOST ZERO DAMAGE! These clear cubes have stopped coming out, and it is too bad, because they are amongst the most pristine fluorites that have ever been found. Have you ever seen hundreds of them together on one specimen? This is just an astonishing piece for its size and richness. Ex. Fersman Museum of Moscow back in the early 90s, probably 93-95.
6.7 x 5.4 x 4.7 cm. A superbly and supremely, gemmy and lustrous, 4.5 cm, bi-colored, indicolite-blue and emerald-green tourmaline crystal aesthetically set on a very complex, glassy, colorless to smoky, fenster quartz crystal. This showy and very fine specimen is from the famous Sao Jose da Safira area of Minas Gerais, Brazil. Ex. John Barlow Collection, #2836.
