2.3 x 2.0 x 1.6 cm. A bi-colored, pink and green tourmaline flanked by and coated on the back with needle quartz crystals.
9.7 x 7.5 x 6.8 cm. A UNIQUE, UNUSUAL and SHOWY pseudomorph of quartz after quartz and very nicely accented with lustrous, iridescent, black brookite crystals. This fine, old-timer hails from the famous Magnet Cove District of Arkansas. The specimen is dominated by a large, euhedral quartz pseudo. You can see the cavity in the termination where a brookite crystal was dissolved out. The scattering of sharp brookites highlight this uncommon and excellent piece from a CLASSIC locality. Ex. George Feist Collection.
7.0 x 5.3 x 3.0 cm. A VERY AESTHETICALLY SCULPTED, nearly pristine, MATRIX quartz "prase" from Seriphos Island, Greece of green hedenbergite included in lustrous quartz spears. SUPERB for the size, with dramatic visual appeal. Matrix specimens of this quality are seldom available.
9.9 x 5.6 x 4.2 cm. This pyrite specimen would not win any awards if it were Peruvian, but this is an old BUTTE piece, and therefore is good for what it is, quite aesthetic! What makes it pretty is that the pyrite crystals (which do have a fine brassy luster!) are intergrown with accenting areas of quartz crystals, which sets the pyrites off nicely. Ex. Feist Collection.
6.8 x 5.9 x 4.2 cm. A cluster of glowing green fluorite with a beautiful pebbly surface that has grown around and all but engulfed two large quartz prisms. Accompanied by a 1999-dated Collectors Edge label - was in the collection of Ed David in the 1990s, and sold to George Elling Collection at some point. Really unique piece, to this day. This is a style, and a richness of fluorite, seldom seen for the locale.
12.9 x 9.4 x 6.6 cm. This is a spectacular and large North Carolina specimen - a huge compound crystal intergrown with a second crystal, on a thin sheet of matrix. The compound crystal is complete all around and doubly-terminated, with multiple terminations on one end. The crystal intergrown with it is also complete and undamaged (it has only one termination - the other side has grown against the larger crystal) and is incredibly gemmy. For size, condition, completeness and overall aesthetics, you could hardly do better than this for a North Carolina amethyst. Ex. Feist Collection.
6.9 x 5.9 x 5.6 cm. These Georgia amethysts have a very distinctive bright purple glow to them; put them under a halogen and they look almost neon. This is a cluster of several intergrown crystals, with glassy luster. Good American amethysts have always commanded a premium compared to those from the prodigious amethyst localities around the world; they are just not common at all. Ex. Feist Collection.
5.7 x 1.8 x 1.6 cm. Check out this amazing Brandberg specimen out of the Charlie Key collection! What you have here is a strange TABULAR amethyst crystal (with a smaller crystal growing behind it) that has grown right on the termination of a milky, colorless quartz crystal. The amethyst has intense, deep purple color and a subtle phantom. Very different for Brandberg, and for anywhere in fact.
17.4 x 11.9 x 7.4 cm. A RARE, HUGE matrix tourmaline specimen from the Little 3 Mine in California, dug in teh 1960s or 70s, dear to so many of the local SoCal collectors’ hearts! This spectacular piece came out of the well known San Diego collections of Irv Brown and Chuck Houser. It came originally from Dr. Peter Bancroft, author of Gem & Crystal Treasures, and was a companion piece to a famous large specimen that Dave Wilber had in the 1970s in his displays. The Little 3 is one of the more geologically disrupted pegmatites in San Diego and large specimens are almost unheard of, and pieces of this size tend to come in pieces in situ, by the time we find them. Not surprisingly, it needed a few repairs to put it back together after removal from the pocket (at least 3, but they are not visibly detracting) ; but as you can see, the repairs are clean and it looks the way Mother Nature intended it to. We shot it under strong light so you could see the color in these dark tourmalines. They are just HUGE - measuring over 4 cm across the termination! (The taller one is 6 cm in height.) They sit aesthetically right next to a large, euhedral, translucent quartz crystal, on a carefully-trimmed matrix of bladed cleavelandite.
20.9 x 13.0 x 8.9 cm. This BIG specimen is amazing not just for the beauty of the combination of species, but for the calcites themselves. They grew in two completely different forms, on the same specimen: scalenohedrons, and flat nail-head crystals. Some of the crystals are part one and part the other - just incredible from a crystallographic standpoint! The crystal grew part-way up then rose to a pointed termination in one area, with the rest of the crystal continuing up to a flat top that wrapped itself around the point of the scalenohedron!!
9.7 x 5.6 x 5.5 cm. A UNIQUE and FACINATING, blue-green indicolite tourmaline on a large quartz crystal from the famous Barra de Salinas Mine of Brazil. Tectonic forces in the pocket broke the tourmaline in half, and the quartz crystal grew around the tourmaline pieces. The tourmaline break healed, so the 3.6 cm main crystal is now doubly terminated! This is a really showy specimen, which reflects earth forces at work. There is some contacting at the quartz termination, but this is such a unique piece, that it is really not detracting. The broken and healed indicolite on the large, sharp quartz crystal is the focal point.
14.0 x 11.0 x 7.5 cm. A STRIKING CABINET specimen of mirror-bright, stepped-face and spinel-twinned galena crystals aesthetically set on a bed of transparent, colorless quartz crystals from recent finds at the Borieva Mine at Madan, Bulgaria. A classic and very showy sulfide specimen with very few broken quartz crystals. The quartz crystals are preferentially dusted on the backside with tiny chlorite crystals, which gives the crystals the greenish-gray appearance. Accompanied by an old label from the 1990s.
13.0 x 8.5 x 8.0 cm. A BIG specimen featuring a long, shallow vug filled with balls of malachite with a sparkly, microcrystalline surface, and equally sparkly quartz, on a bed of underlying chrysocolla. This large matrix is made up mostly of massive chrysocolla and azurite. This is an old-timer copper-mineral combo specimen from the Inspiration Mine.
8.7 x 1.9 x 1.6 cm. This doubly-terminated schorl tourmaline crystal has the distinction of having a gemmy quartz crystal growing right off of one of its terminations - with little needle schorls growing inside of IT! (That makes it a schorl in quartz on schorl!). The schorl has good luster on its striated side faces.
8.4 x 2.0 x 2.0 cm. A dramatically SCEPTERED amethyst/smoky crystal from Brandberg, with the blushes of color, gemmy clarity and glassy luster that make these so famous. Sceptering is still not entirely understood; but because it is relatively rare, it adds value to crystal specimens. This crystal also has a tiny enhydro (bubble) inside it that moves in a narrow channel of trapped water.
