10.2 x 6.4 x 6.4 cm. Gemmy and lustrous, golden-amber baryte blades to 4.5 cm are attractively coated by sparkling pyrite microcrystals on this beautiful cabinet specimen from the Meikle Mine of Nevada. The baryte blades are piled up, jackstraw-fashion, on matrix. The dominating, upright crystal is in good shape. Broken and contacted crystals are noted, but this is a very interesting specimen of the uncommon association from this well-known locale and a small find there in the late 1990s. Ex. Scott Kleine Collection.
3.4 x 3.2 x 3.0 cm. A large, sharp and lustrous, battleship-gray tetrahedrite crystal nicely accented with a lustrous, brass-yellow pyritohedron on one face from the long-extinct Daly-Judge Mine of Utah. Two of the three faces are well-crystallized, with the third, out of sight face being contacted. A large, seldom available tetrahedrite crystal from this old-time, well-known locale. Ex. Ydren Collection.
6.0 x 4.0 x 2.3 cm. Lustrous, brassy, columnar, blocky and flat-topped bournonite crystals characteristic of the 1980s finds at Quiruvilca are richly and aesthetically scattered on the sculptural pyrite matrix. Ex. Tarnowski Collection.
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.
9.4 x 7.2 x 5.9 cm. An aesthetic, complete pyrite concretion from a new Chinese find. This striking, flattened ball of parallel bands of sparkly pyrite microcrystals on shale looks like a hand-woven basket or clay pot with a stylized "spout" on one end. A unique and fine specimen.
11.5 x 9.0 x 5.0 cm. China has recently provided us with an amazing variety of calcite specimens of all habits, colors and sizes. This striking cabinet specimen features a multitude of glassy, translucent, light amber, nail-head calcite crystals with incredible oriented overgrowths of pyrite microcrystals. Nearly every calcite crystal has pyrite on it. The riveting primary crystal is 4.2 cm across.
Hard to capture on camera, but these sharp, scalenohedral calcites (to 3 cm) are dusted with bright pyrite microcrystals to create a big, dazzling Russian showpiece. A couple of tip dings, but hard to notice on a specimen such as this. VERY ATTRACTIVE and, even in the midst of tonnes of minerals, unusual for russia. 11.8 x 6.8 x 5.2 cm
A STUNNING specimen in every way. It features lustrous, doubly-terminated calcites to over 3 cm that have grown on a cluster of blue-green fluorite that is layered with a coating of bright, sparkly pyrite selectively deposited on various faces of the fluorites! VERY COMPLEX AND INTERSTING associations here, that are better in person...! 12 x 8 x 4.3 cm
5.5 x 5.3 x 4.1 cm. An exceptional specimen of Enargite altering to Luzonite. The black blades of Enargite, which can reach 1.1 cm in length, have excellent luster, and the striations on the faces add greatly to the aesthetics. The Luzonite is growing on the terminations of many of the crystals of Enargite. The Enargites surround a bed of beautiful lustrous Pyrites. Ex. Charlie Key.
4.8 x 4.7 x 3.5 cm. The locality of Kara-Oba in Kazakhstan has produced some very attractive Ferberite specimens over the years. This piece is a very aesthetic crystal group featuring sharp, bladed, striated blades of Ferberite measuring up to 1.4 cm which are associated with sparkling cubic Pyrite crystals and even one small pale green Fluorite cube. A great association piece and a nice miniature specimen from this well known locality in central Kazakhstan.
An unusual and very desirable COLORADO specimen: a pyrite cluster that is SILVER in color due to a coating of molybdenite! The crystals are sharp and lustrous. It is quite strange to see a specimen of silver color that to the mind SHOULD be golden! There are hints of the golden color coming through here and there, adding attractiveness to the piece. 5.1 x 4.5 x 4.0 cm
A complete floater, complete all around that is, that looks like the head of a medieval mace! The crystals stick out in all directions from the center and make this a most unusual Spanish pyrite (normally they are just simple cubes!). ex. Dr. Gary Hansen dealer stock and not shown since early 1980s. 5.1 x 5.1 x 5 cm
5.4 x 3.5 x 3.1 cm. Lustrous, sharp, brass-yellow pyrite crystals nearly cover this elongate, rounded, egg-like shale concretion from the Dallas-Fort Worth Airport. This is a pristine, floater specimen. This locality is now extinct, as runway expansion obliterated the stream bank, where these were found in a Cretaceous shale layer.
8.8 x 7.4 x 5.5 cm. A striking fluorite cube fully covered with pearlescent, flattened calcite rhombs and sparkly, iridescent pyrite microcrystals from recent finds at the well-known El Hammam Mine of Morocco. The translucent fluorite is sea-green with a purple exterior. Outstanding purple fluorescence on the fluorite and orange fluorescence on the calcite. This is unusual material that came out a few years ago.
14 x 10 x 5 cm. A wonderful “ridge” of brilliantly lustrous Huanzala pyrite. This freestanding piece has very well formed, striated cubes on three sides, and some cubes have slight octahedral and dodecahedral modifications. This is a fine specimen that is beyond the average for the luster, the symmetry, and the crystal details of those fine lines etched onto the faces that make light reflect so brilliantly off many subfaces.
