6.3 x 4.4 x 2.9 cm. A rich fan of the most prized quartz varietal rose quartz, from Brazil. This cluster sits on a small bit of colorless quartz, and can be displayed from either side. The crystals have good saturated pink color and a silky luster.
4.2 x 2.1 x 2.0 cm. An aesthetic divergent cluster of very glassy, rust-red, hematite-included quartz crystals from recent finds near the Orange River of South Africa. For the species, they are definitely world-class. The translucent quartz crystals have very neat stepped growth faces and the interior phantoms at the terminations of ALL of the quartz crystals are stunning. Nearly damage-free, with only the slightest of edge wear on one termination. This Photo was Mindat.org Photo of the Day - 19th Jun 2008
5.5 x 5.0 x 1.5 cm. A beautiful and aesthetic crossed pair of lustrous and translucent, green, hedenbergite-included quartz "prases" from Serifos Island, Greece. The smaller crystal is a doubly terminated and pristine and the large crystal is damage-free, except for the point of contact. This is a showy, complete all-around classic from the Gilbert Gauthier Collection.
4.1 x 3.1 x 2.5 cm. A thick, tabular, hexagonal molybdenite crystal beautifully set on milky quartz matrix from a classic Quebec locality - Moly Hill. Classic crystal form, splendent lustre and aesthetic composition on this fine piece from the Charles Hansen Collection.
2.4 x 2.4 x 1.7 cm. An OUTSTANDING and RARE, flattened, Japan-law twin quartz crystal from a MOST UNCOMMON Montana locality - the PC Mine in Jefferson County. The nearly pristine, water-clear quartz twin has bubbly quartz crystal phantoms arcing upward at the middle of the crystal from the base. A second, very sharp quartz crystal hides on the back. Specimens of this quality came out in the 1960s to early 1970s. Ex. Dick Jones Collection.
5.2 x 5.0 x 3.2 cm. Two highly lustrous, complexly twinned, dark brown cassiterite crystals to 1.8 cm jauntily perched on breccia matrix and nicely accented by smoky quartz crystals from the well-known Elsmore area tin mines of New South Wales. The large crystal is very aesthetically set atop matrix and both cassiterites are PARTIALLY GEMMY, with distinct areas of red fire. Ex. John Ydren Collection.
5.6 x 5.0 x 4.6 cm. Super lustrous, jet-black schorl prisms in parallel- and perpendicular-growth form a very aesthetic specimen from the Erongo Mountains. The large vertical schorl "crown" is striking and the quartz needles at each end are a very nice accent. The schorls in the front are doubly terminated and there is only a bit of contacting on each side. A high quality Erongo schorl specimen.
9.5 x 3.0 x 2.2 cm. A beautiful and striking, complete all-around amethyst crystal with complex, chevron-shaped, color zoning and a gorgeous, contrasting, water-clear, pyramidal termination. Excellent material. The very light contacting on two sides, with no damage, per se and the infinitesimal bruising on one termination edge are barely noticeable and are certainly not detracting, in the overall context of this showy piece.
5.5 x 2.2 x 1.8 cm. A GEM, doubly terminated, smoky quartz crystal beautifully attached to the side of a PRISTINE, 4-sided, highly lustrous, jet-black aegirine crystal and nicely complimented by smaller aegirines from recent finds at Mt. Malosa, Malawi. A couple of the sidecar aegirines have broken ends, but certainly not detracting to this very aesthetic specimen.
10.2 x 5.0 x 2.3 cm. This specimen is a great small cabinet size piece consisting of super quality, sharp, gemmy, highly lustrous, prismatic, light purple color scepter, "reverse" scepter and simple prisms of Amethyst measuring up to 1.0 cm sitting atop white/colorless, modified rhombohedra of Calcite on matrix. This piece is remarkable for Bolivia as it is from an "Alpine-type" locality, and features a type of crystallization that is virtually unheard of from Bolivia. Ex. Brian Kosnar.
7.4 x 6.2 x 3.4 cm. From the new find of the Fall of 2004. These new Brookite specimens are some of the finest quality "Alpine-type" Brookites in the world. Reminiscent of the finest TRUE ALPINE Brookite specimens from the Italian and Swiss Alps, these crystals are just as sharp, lustrous, gemmy and colorful. This particular specimen features a superb quality, razor-sharp, lustrous, gemmy, fiery red-orange colored Brookite crystal with a classic black "phantom" running the length of the crystal. To top if off, the Brookite is sitting atop gem quality Quartz crystals on matrix. Ex. Richard Kosnar Collection.
3.6 x 1.7 x 1.3 cm. Here we have a beautiful association of light sherry colored Topaz crystals with Quartz. Pakistan has long produced some of the finest Topaz specimens in recent memory, and to find them with any kind of associations is remarkable. The Topaz crystals on this specimens are very sharp, gemmy and glassy with a light sherry color; it is really the aesthetic quality of the two Topaz crystals growing on each side of a thin, frosted Quartz crystal shard. Ex. Richard Kosnar Collection.
16.2 x 12.3 x 5.7 cm. Datolites from Dal'negorsk are among some of the finest quality Datolites in the world, not to mention large and colorful. This piece came out of Dal'negorsk about 10 years ago, and is simply a unique and attractive specimen of this material. It features large, sharp, highly lustrous (in areas), gemmy green blocky crystals of Datolite with associated stubby Smoky Quartz crystals which are coating much of the Datolite crystals. The Datolites themselves have some very interesting parallel etching patterns throughout the crystals, giving it a very one-of-a-kind appearance. The largest Datolite crystal measures 8.2 cm across, which is very good sized for this locality. Ex. Richard Kosnar Collection.
12.5 x 7.8 x 5.5 cm. The quarry at Upper New Street is over 100 years old (it opened in 1893). During the mid 1980's to early 1990's, there was a lot of collecting that took place between the Upper New Street and Lower Street Quarries in an area that is affectionately referred to by some as "Middle New Street". The majority of the specimens from this area are still labeled as being found at Upper New Street even though they were not found in the quarry itself. Nonetheless, this is one of the most famous Trap Rock quarries in New Jersey and is probably most famous for its amazing and unique Prehnite casts after Anhydrite (sometimes called "fingers" or "snakeheads"). This specimen features several sharp, lustrous, pearly, cream-colored, rhombohedra of Chabazite measuring up to 1.5 cm associated with Heulandite and minor Calcite on Quartz on basalt matrix. Ex. Richard Kosnar Collection.
12.4 x 9.3 x 3.3 cm. On a trip through Argentina in 2003, collector Dave Stoudt picked up a number of unusual specimens that are not often seen on the market - including this rich plate of shimmering, translucent green fluorite. It appears almost botryoidal on the surface, but it is actually composed of tightly-massed octahedra.
