10.9 x 7.8 x 6.9 cm. Sparkly pyrite covers strange narrow, peak-like crystals of elongated pyrrhotite (classic for the locality, but rare in this replacement form by pyrite), with little snowballs of gypsum scattered here and there for accent. Ex. Dave Stoudt Collection.
7.3 x 5.3 x 4.0 cm. Radiating clusters of splendent, brassy millerite needles encircle a melted-look nodule of arsenian pyrite on this superb and unusual specimen from the famous Meikle Mine of Nevada. The millerite clusters look like a wreath or tiara on the pyrite. The exact mine location is the 41-20 Heading of the Griffin Ore Body.
9.4 x 6.2 x 5.3 cm. This is a large, pristine cube, wonderfully isolated and fully exposed on the matrix. It measures 2.8 cm on edge and has a mirror-golden luster.
11.6 x 10.6 x 8.9 cm. A dramatic specimen from this really unusual find of three years ago, where golden pyrite formed along the edges of very large crystals of translucent calcite. This one has really nice coverage on the edges, and is a large and rich example from the find.
3.2 x 3.1 x 3.1 cm. A glorious floater crystal of pyrite from Navajun, with beautiful bevels and face striations, and little sub-crystals poking out of some of the faces. This really unusual crystal was in the collection of Gene Meieran.
7.4 x 6.9 x 5.2 cm. A very unusual Mexican combo specimen that combines sharp, brassy octahedrons of pyrite with translucent crystals of grossularite and books of platy hematite. This is an old-timer.
6.4 x 5.9 x 3.7 cm. This superb Oppu Mine pyrite came out of the noted collection of Gene Meieran. The crystals have a wonderful golden gleam to them, in addition to these pretty striations on the faces. And the overall form is beautiful too, because this happens to be a knob or dome, covered all around with crystals (with a few quartz crystals sticking out).
A RARITY indeed! From Tsumeb, pyrite in crystalline form is quite uncommon and this is as fine a thumbnail example as I have seen , featuring a near-2-cm crystal stacked atop others, like a snowman. Acquired 8-15-1986 2.7 x 1.75 x 1.5 cm
An excellent, pristine cluster of lustrous, brassy and striated pyrite pyritohedrons from the famous Colorado mining district of Rico. Rico produced some of Colorados finest pyrite. Old material, as the last mine closed in 1971. See the Mineralogical Record May-June 1985 issue. Ex Gene Meieran Collection. 7.5 x 5.7 x 4.3 cm
An excellent and unusually shaped cluster of lustrous and brassy modified pyrite cubes from Zacatecas, Mexico. This piece can be rotated many different angles for viewing. A totally pristine floater. Ex Gene Meieran Collection. 7.7 x 6.5 x 6.1 cm
9.1 x 5.9 x 2.2 cm. A rich plate of very unusual pyrite crystals, roughly octahedral but with complex sub-faces that give them an almost "scaly" look. Ex. George Feist Collection.
5.9 x 4.2 x 2.7 cm. A complexly twinned, 8 mm, lustrous, brassy pyrite crystal perched atop a jagged "mountain" of matrix from the large open-pit siderite mine at Erzberg, Styria, Austria. Ex Rolf Wein Collection.
2.3 x 2.2 x 1.6 cm. An unusual and fine showy gold thumbnail from the unique 1990s Newfoundland find, at St. Johns. Bright, microcrystalline gold is aesthetically perched atop the unique, pink granitic quartz and feldspar crystals. A thin band of black, host rock matrix and bright pyrite is an excellent compliment.
2.25 x 2.25 x 2 cm (both). Most of the Spanish pyrites you see these days are the cubes from Navajun. But here are a couple of weird and beautiful compound crystals from a different locality, featuring interpenetrating cubic forms that are sculptural and pretty. Ex. Feist Collection.
14.3 x 9.0 x 7.8 cm. A superb combination specimen from Peru, combining long, slender, transparent quartz crystals with a silky surface luster with finely-articulated sphalerites on a hint of sparkly pyrite on the base matrix. Ex. Richard Hauck Collection.
