7.4 x 5.7 x 4.6 cm. A highly lustrous, 4.5 cm, step-faced, galena cube aesthetically set on sphalerite matrix and very nicely accented with purple fluorite from the Elmwood Mine. Highly representative of the species, association and locale. Ex. Mullane Collection.
9.0 x 8.7 x 3.1 cm. A sculptural specimen from the Elmwood Mine. Glassy calcite crystals, some doubly terminated, and two clusters of ruby-jack sphalerite crystals are aesthetically scattered on the naturally fractured plate of silicified limestone, that is covered with sparkly, drusy quartz crystals. Quartz is really not that common from Elmwood, so this is an exceptional combination piece. Ex. Mullane Collection.
3.5 x 3.0 x 2.4 cm. A fine, splendent, cruciform or cross-shaped, stepped-growth, 2.3 cm, galena cube perched atop highly lustrous and gemmy, ruby-jack sphalerite from the Elmwood Mine. The form of this galena crystal is really striking. Ex. Consie Prince old dealer stock from the 1970s.
10.4 x 7.5 x 5.8 cm. A fine cabinet specimen of a few cherry-red rhodochrosite rhombs and a dusting of brassy pyrite microcrystals on starkly contrasting, highly lustrous, twinned, black sphalerite crystals. This highly representative combination specimen is from recent finds at the Wudong Mine of China.
Textbook, super-lustrous sphalerite crystals, complete all around and measuring to 1.7 cm across, piled up beautifully amidst bright pyrite, some of it having grown on silvery arsenopyrite crystals. 5.1 x 4.5 x 4.0 cm
As specimens such as this disappear quickly from the market with the mine now closed, you appreciate them more and more. This is a doubly-terminated twin of golden calcite, with both gemmy tips complete, perched right on top of several transparent purple fluorite crystals, which in turn sit on a bed of crystallized sphalerite! The calcite twin measures 8 cm, and shows only a minuscule bit of edge wear on the tip, in fact QUITE minimal considering the vast majority of these show wear. This is a really showy and beautiful Elmwood combo piece! 8 x 8 x 7.4 cm
An exquisite mini with long, slender, elegant quartz crystals jutting from a contrasting sphalerite matrix accented with super-bright pyrite cubes, 4.7 x 4 x 3.1 cm
7.9 x 6.0 x 5.1 cm. Superbly crystallized, lustrous, black sphalerite crystals with red highlights, to 1.7 cm in length are the host for two discrete rosettes of light tan baryte, to 3.25 cm across along with a single, glassy and gemmy, lavender colored fluorite crystal, to1.1 cm across. Obtained in the 1980s from Ken and Betty Roberts. Ex. Jack Halpern Collection.
4.2 x 3.4 x 2.1 cm. A fascinating and striking pseudomorph miniature specimen from a small find that was brought out at Munich in 2006. These very unusual, barrel-shaped crystals are actually epimorphs, i.e. casts after calcite crystals, which have been dissolved away. Microprobe analysis in South Africa by Bruce Cairncross and others shows that the shimmering, metallic-like coating is a mixture of siderite and sphalerite. The piece is very light weight for its size and, in fact, the cast is hollow. Complete all-around and pristine.
12.0 x 7.2 x 4.0 cm. A fine cabinet specimen of mirror-bright, twinned, black sphalerite crystals to 1.9 cm from the Krushev dol Mine of Bulgaria. This large, essentially pristine, undulating plate is beautifully accented by water-clear, quartz needles.
7.5 x 6.3 x 6.1 cm. A fine and beautiful fluorite cube attached to a bit of sphalerite matrix from the Elmwood Mine and the Consie Prince Collection. The glassy, translucent, light purple cube has beautiful, stepped-growth faces. The color is very pleasing - lighter than normal and so more translucent to light.
3.7 x 2.0 x 1.2 cm. A fine cluster of brilliantly sharp, stepped-growth face, twinned sphalerite crystals to 2.2 cm dusted with pyrite and a spray of quartz needle. Classic, seldom seen combination material from this long-closed locality. Ex. Jaime Bird Collection.
8.4 x 4.9 x 4.6 cm. Johannsenite is a rare pyroxene group silicate and this excellent, combination specimen features a very rich coverage of sprays of black to brown to olive green johannsenite needles on the 3-dimensional matrix. A fine bonus are the two, very well-placed, gem, olive-green sphalerite crystals to 1.1 cm. This piece is from the Iron Cap Mine of Arizona. Ex. J.H. Marshall Collection.
9.0 x 3.9 x 3.8 cm. Jordanite is a rare lead, arsenic, antimony sulfosalt and this fine combination specimen is from the Type Locality - the Lengenbach Quarry in Switzerland. A 1.1 cm long aggregate of lustrous, lead-gray, prismatic jordanite crystals is beautifully adjacent to or near to gorgeous, gem, yellow-brown sphalerite crystals to 1.0 cm. These crystals are very attractively lined up on a sculptural matrix of classic, sparkly, sugary, layered, Lengenbach Quarry dolomite. The sphalerites are large for the Lengenbach Quarry. Ex. Mullane Collection. Old material.
4.6 x 3.5 x 2.2 cm. This piece features a sharp, gemmy, deep purple cubic crystal of Fluorite measuring 1.8 cm on edge smartly perched atop a mound of crystallized reddish-brown Sphalerite. A classic example of an Elmwood Fluorite on matrix.
