13.9 x 4.1 x 4.1 cm. A classic, water-clear, cabinet-sized quartz crystal from the Hot Springs area of Arkansas and the John Ydren Collection. This complete-all-around, older specimen has a striking, steep pyramidal termination and beautiful, stepped-growth faces. Very nearly pristine.
7.2 x 6.5 x 3.4 cm. A very dramatic example of this classic combination from the Ray Mine, most common in the 1990s, now hard to come by. This piece has stalactites to 2 inches, covered by a thin layer of quartz druse. Only one stalactite, the peripheral one to far left, is broken. The others are all complete and pristine. From the 1900 level.
8.6 x 2.9 x 2.7 cm. An excellent and very showy, doubly terminated, floater quartz crystal from the Messina Mine of South Africa and the Jaime Bird Collection. This translucent specimen has a glassy, sharp, primary termination and a broken, healed and regrown, multiple, secondary termination. Two-thirds of the crystal is encased in secondary, sidecar, quartz crystals. And there are two generations of iron oxides on this fine crystal: the hematite tinting giving the crystal the reddish-brown color; and the preferential coating of sparkly, specular hematite.
17.9 x 9.8 x 6.5 cm. A stunning, 9.0 cm, lustrous, brassy, compound pyrrhotite crystal beautifully and aesthetically rests amongst milky quartz needles on this outstanding large cabinet specimen from the Nikolaevskiy Mine at Dalnegorsk. A couple of smaller pyrrhotite crystals are a nice accent. The accompanying label from a Russian dealer indicates that the piece was mined in 1992, during the height of material coming from Dal’negorsk.
11.8 x 6.5 x 5.0 cm. Three gemmy and lustrous, polychrome tourmalines to 5.6 cm are dramatically embedded in the side of a glassy, transparent to translucent, complete-all-around cabinet quartz crystal from recent finds at the Pederneira Mine. The placement, composition and color contrast of the tourmalines on the side of the sharp quartz crystal are stunning.
6.8 x 4.8 x 3.8 cm. An excellent and aesthetic smoky quartz, amazonite and goethite combination specimen from a new find at the Dreamtime Mine of Colorado. A 5.4 cm, glassy, translucent to translucent smoky quartz crystal very aesthetically angled and sits in front of a highly complimentary matrix of lustrous, blocky, twinned, light turquoise-blue amazonite crystals and lustrous, earthy-brown, blocky goethite pseudomorphs after siderite crystals. The smoky quartz is complete-all-around and is pristine. This is a showy, classic-style Colorado combination piece with no repairs. Ex. Adam Sotomayor, who collected it.
3.7 x 3.4 x 2.0 cm. Iridescent, sharp, isolated to intergrown, bornite crystals are aesthetically set on a plate of colorless quartz crystals on this fine specimen from the Dzhezkazgan Mine of Kazakhstan. Classic and highly representative material from this well-known locale. Once moderately common, they are now available only from recycled collections. Ex. Tarnowski Collection.
11.3 x 7.2 x 4.5 cm. A striking and aesthetic cluster of parallel-growth smoky quartz crystals with beautiful amethyst highlights and interesting interior features from the Goboboseb Mountains of Namibia. The crystals are water-clear, very glassy and have interesting faces. The tabular crystal on the left, center is unusual. This fine piece is very nearly pristine.
7.3 x 6.2 x 4.2 cm. Razor-sharp, glassy, ink-black, smoky quartz crystals with a hint of gemminess are nicely framed by muscovite books and feldspar crystals on this very aesthetic specimen from the less well-known Dinkey Creek Mine of California.
17.3 x 11.0 x 7.0 cm. A dramatic, large cabinet amethyst plate from Artigas, Uruguay. This striking specimen has gemmy, glassy crystals with intense purple color and fabulously highlighted by tan spherules of devitrified quartz glass. The spherules look like eyes peering out from the amethyst. Very nearly pristine.
6.3 x 5.0 x 3.8 cm. An old-time, showy combination specimen of sharp, beautifully striated, lustrous, brass-yellow pyrite crystals to 1.2 cm scattered on a sculptural matrix covered with frosted quartz crystals to 4.0 cm. Ex. Mullane Collection and comes with 3 labels, all saying "Horner, Colorado". My brief research shows no Horner, Colorado locality, but there is a Horner Prospect in Taos County, New Mexico. The Horner Prospect in New Mexico is located in the northern part of the state, very close to the Colorado border, but is definitely on the New Mexico side.
2.4 x 2.2 x 1.6 cm (largest). A rare and superb, 4-piece set of striking, glassy, lustrous, blue-gray, dipyramidal quartz crystals colored by aerinite inclusions from near Malaga, Spain. Aerinite is a rare silicate, found worldwide almost exclusively in Spain. Each of the four, pristine compound crystals has unique character. A well-written article on this find is found in the Mineralogical Record, Volume 27, Number 2, March/April, 1996.
2.4 x 2.4 x 1.0 cm. A fine and aesthetic, two-sided, bright and rich gold on quartz thumbnail from the Eagle’s Nest Mine and Mark Mauthner Gold Collection. The body of flattened, layered gold leaves has a feather of spinel-twinned gold crystals and is beautifully crowned by a 3-dimensional, 6 mm, octahedral gold crystal. From the Frenchman’s adit of the mine.
11.5 x 6.0 x 5.2 cm. An impressive, stout, water-clear, cabinet quartz crystal from the Mawi Pegmatite of Afghanistan and the Richard Hauck Quartz Collection. The base of the crystal rests on glassy, gem orthoclase variety adularia, smaller quartz crystals, matrix and partially hidden on the side, a gorgeous, 9 mm, gem, purple apatite crystal. The pristine, complete-all-around termination holds a striking inclusion, probably plates of tantalite or stibiotantalite. The back of the termination is lightly frosted and tinted with green chlorite. A most interesting, older quartz associaton piece from the well-known locale, especially with the gem apatite.
6.3 x 4.6 x 2.8 cm. Camp Robin is a new Madagascar locality and this excellent piece is from the 2006 find. A 3.7 cm, bi-colored, doubly terminated liddicoatite crystal is perched on the side of a sliver of intergrown, partially euhedral smoky quartz crystals. The terminations are a very vivid pink and contrasting center is black on this lustrous and translucent crystal. The termination is moderately lustrous and the crystal is complete-all-around and pristine. Striking and highly representative material from this recent find.
