4.9 x 2.9 x 2.2 cm. A beautiful amethyst specimen. Fine, glassy, translucent to transparent, purple crystals of amethyst stand side by side. The crystals really sparkle and are called "cactus quartz" for their form. The terminations are isolated, while the bodies have a prickly, "cactus" look with an overgrowth of smaller crystals. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range. A lovely example with great color and the iron oxide inclusions are a very nice accent. Complete-all-around and nearly pristine.
6.5 x 6.1 x 4.1 cm. Water-clear, gemmy, quartz crystals to 1.5 cm are richly scattered on the pastel-pink rhodochrosite on this beautiful combination specimen from Taxco, Mexico. Many of the flat-lying quartz crystals are so clear, that it is very hard to see them. The aesthetics of the sculptural mound of rhodochrosite and protruding quartz points on contrasting matrix are striking.
2.9 x 1.9 x 1.3 cm. A striking toenail from the Carl Davis Collection. A pristine, complete all-around, water-clear quartz crystal encloses highly lustrous, golden rutile needles. The long needles look just like golden straws.
7.8 x 6.0 x 5.9 cm. These elegant Lechang quartzes have such a "classic" look to them, with their subtle rusty-red hematite inclusions giving them a look similar to some English calcites. This piece is particularly fine, with the two, red, "rabbit ears", the water-clear quartz crystals, especially the needles and the hematite "iron rose". The long "red" is 5.5 cm in length and both "reds" are pristine.
12.5 x 12.2 x 5.4 cm. Sharp, vivid purple fluorite cubes with outstanding gemminess and lustre form a superb, 3-dimensional cabinet plate from the famous, but less well-known Deardorff Mine of the Illinois Fluorspar District. The two largest cubes are 3.8 and 3.6 cm wide. The fluorites are beautifully accented by scattered quartz crystal clusters and there are even a few ruby-jack sphalerite crystals. This is classic, old-time material from this mine dating from the 1930s to 1950s, as the mine closed in the early 1960s.
8.3 x 6.5 x 5.4 cm. A fine, old-time cluster of glassy and transparent amethyst crystals with pleasing variable purple color intensity from a classic South Carolina locality - Due West. The dramatic, compound, doubly terminated crystal is 8.0 x 3.3 cm and has fabulous, deep purple tips. The small bed of milky quartz crsytals is a very nice accent. The purple color variations are really highlighted in the photo. Ex. George Feist Collection.
The photos just didn’t adequately pick up the fine luster of these elegant huebnerite blades. They are staggered from front to back, giving the specimen good 3-dimensionality. A few of the terminations are incomplete, but most are intact. Quartz crystals add a pretty accent. 6 x 4 x 3.5 cm
5.8 x 4.5 x 3.9 cm. Clusters of gem, yellow fluorite cubes to 6 mm are scattered on the vuggy, 3-dimensional, amethyst matrix on this fine and uncommon combination specimen from Thunder Bay, Ontario. There is also pink, bladed baryte on this piece. Thunder Bay is world-renowned for amethyst and to see starkly contrasting, yellow gem fluorite cubes on purple amethyst is a very pleasant surprise.
8.4 x 6.7 x 5.0 cm. Lightly iridescent, splendent metallic-gray bournonite crystals to 1.5 cm are richly scattered amongst milky quartz crystals on this fine and uncommon specimen from the Milpo Mine of Peru. Many of the bournonites have the classic and textbook "cogwheel" crystal form. The 3-dimensional matrix is massive sulfides on this fine specimen, which probably dates to the heyday of specimen production from this district in the 1970s to early 1980s. Bournonite from this locality is very uncommon.
3.7 x 3.0 x 2.6 cm. Plancheite is a rare secondary, hydrated, copper silicate. A fine vug on gossan matrix has powder-blue plancheite covered by and highlighted by a multitude of thin, water-clear barite blades and further accented by plancheite-included calcite crystals and a couple of quartz crystals. For the locale, this is a very highly representative combination specimen featuring this rare copper silicate.
You just don’t see a lot of matrix amethyst specimens from Colorado. This one features a 4.2-cm crystal attached to the matrix at the termination, so that from the display face you see its best aspect and not the natural contacts at the back. There are four smaller crystals as well, one intergrown with the main one. Actually, it can be displayed vertically as well as horizontally (shown). THIS HAS EXCEPTIONALLY RICH URAGUAYAN QUALITY COLOR to it, and such pieces are very uncommon. 7 x 4.5 x 3.5 cm
11.0 x 7.7 x 4.5 cm. A fine cabinet combination specimen from the well-known Mex-Tex Mine at Bingham, New Mexico. Alternating rings of light green brochantite, sparkly blue-green spangolite microcrystals and quartz radiate outward from small cluster of glassy quartz crystals. A further interesting highlight is the gemmy, golden-amber, sixling-twin cerussite crystal perched near the edge of the specimen.
5.2 x 2.7 x 2.4 cm. An aesthetic floater cluster of glassy, purple amethyst crystals from a classic North Carolina locality - Iredell County. This very fine doubly terminated example has the typical beautiful color and crystal form of Southern Appalachian amethysts. The crystals are translucent to transparent. The back is contacted, but has no damage, per se, has super-interesting, stepped-growth faces and has two, small embedded quartz crystals. This old-time specimen is very nearly pristine, with only super trivial termination wear on one end. Ex. Don Boydston Collection.
7.8 x 7.4 x 4.8 cm. A striking sphalerite on quartz specimen from the historic Schemnitz mining district of Slovakia. A lustrous, 2.8 cm, twinned, jet-black sphalerite crystal with brown accents is very aesthetically set amongst sharp "mountain peaks" of glassy quartz crystals of very unusual habit. The terminations of the quartz crystals have a strange, secondary overgrowth of water-clear quartz with the sides of the faces having distinctive skeletal features. The quartz crystal terminations have a distinct, five-sided, star pattern, if you look straight down onto the quartz crystals.
5.9 x 4.4 x 3.2 cm. An excellent amazonite and smoky quartz combination specimen from a new find at the Dreamtime Mine of Colorado. A 3.7 cm, glassy, lightly frosted, translucent smoky quartz crystal very aesthetically sits in front of a large, 4.3 cm, lustrous, sharply terminated, light turquoise-blue amazonite crystal. The smoky quartz is complete-all-around and is pristine. Ex. Adam Sotomayor Collection.
