13.9 x 9.9 x 6.8 cm. Lustrous, translucent, sea-green fluorite cubes to 3.7 cm are dramatically and preferentially coated with mirror-bright, brass-yellow pyrite and sparkly, colorless, calcite microcrystals on this fine cabinet specimen from the less well-known El Hammam Mine of Morocco. This mine has produced some unusual and very showy fluorite combination specimens and this piece certainly qualifies. Pristine, except for trivial periphery wear. Weighs 2.9 pounds or 1.3 kilograms.
5.5 x 4.9 x 4.1 cm. An unusual, completely rounded pyrite concretion or aggregate. It is a very interesting piece, and is both complete and attractive. Unfortunately, we do not have a more specific locality unless somebody out there knows it. Ex. Harold Urish Collection.
6.1 x 3.4 x 3.3 cm. An unusual growth of pyrite, which some say forms nucleated around organic remains in the fossil-bearing rocks. This is a complete, cucumber-like tube shape, terminated at both ends and complete-all-around. Certainly, pyrite is unusual for Kansas. Ex. Harold Urish Collection.
10.4 x 7.1 x 3.8 cm. This is an excellent, two-sided, cabinet example of jamesonite, for which Zacatecas, Mexico is famous. The sculptural piece consists solidly of a showy, jackstraw cluster of lustrous to matte-finish jamesonite blades to 2.7 cm. One side holds a 1.3 cm pod of calcite rhombs and pyrite crystals as a nice accent. The crystals are robust on this piece. This fine piece, from the Dave Stoudt Collection, comes from the much less well-known Noria Mine of Zacatecas.
8.5 x 4.9 x 3.9 cm. A striking, translucent, cherry-red rhodochrosite crystal cluster from recent Chinese finds. The large crystal in the front with the fluorite crystal at one end and prominent, stepped-growth faces is 5.0 cm. A sparkly field of small pyrite crystals on the back is a nice accent. Many faces are crystallized and some faces are contacted. This remains an impressive, larger example from this locale.
11.7 x 10.6 x 0.6 cm. These beautiful, lustrous pyrite floater "suns" formed between an ancient bed of shale and clay near Sparta, Illinois. This one is complete-all-around and front and back - and is of rather large size.
12.2 x 7.8 x 3.7 cm. The Eagle mine is probably best known for its pyritohedral Pyrite specimens. This cluster is a superb piece of Eagle mine Pyrite showing classic striated pyritohedra with sharp, lustrous faces. The largest crystal measures 1.4 cm across, and the piece is in fantastic shape overall. A great full sized cabinet piece of this well known material from this now defunct locality. Ex. Richard Kosnar Collection.
5.2 x 2.7 x 1.3 cm. The Siete Suyos mine (Seven Servants mine) is sometimes considered to be part of the Animas mine, and it is often difficult to know where specimens are from because several mines in the area share the same vein system. The good news is that I directly obtained this specimen from the miner who collected it, so I know for certain where it came from. I honestly have never seen any specimens from this locality before. This piece features a few excellent quality, sharp, gemmy, greenish-brown rhombic crystals of Siderite measuring up to 0.8 cm which are sitting upon a crystal of lustrous Pyrite (pseudomorph after a compressed rhombohedron of Siderite) which are associated with minor grey crystals of the rare sulfide, Stannite. The underside of the specimen reveals that the Pyrite is somewhat hollow inside, and actually hosts a second generation of Siderite crystals. For Siderite, the quality is impressive for Bolivia, as I rarely have seen such sharp and gemmy crystals from any Bolivian locality.
11.4 x 7.5 x 3.8 cm. A seldom-seen, classic and very fine cabinet combination plate from the historic mines at Trepca. Snow-white balls of tiny, glassy siderite crystals richly and aesthetically cover the sculptural specimen of brassy pyrite pyritohedrons, dark gray arsenopyrite crystals and a small forest of quartz crystals. Throw in a few, colorless, poker-chip calcite crystals and you have an outstanding combination piece from this famous locale. Ex. Franz Saller Collection.
10.5 x 9.5 x 6.0 cm. Striking clusters of pretty, pastel-purple, lightly frosted, lustrous and translucent amethyst crystals are very aesthetically scattered on the cabinet matrix plate covered with brilliant, brass-yellow, striated, pyrite pyritohedrons and iridescent, brassy chalcopyrite crystals. The amethyst crystals reach 5.0 cm - rare for this locality. This is a pristine, classic and beautiful, large combination specimen from the famous mines at Cavnic, Romania. Very little new material is coming from these historic mines. Ex. Brent Lockhart Collection.
This wonderful tri-state piece, mined in 1993, is interesting on BOTH sides. On one, it consists of pretty, transparent nailhead calcites, with galena and pyrite crystals adding an accent. On the backside are pseudomorphs of pyrite after anhydrite crystals - having completely replaced the anhydrites while retaining their platy form. 10.2 x 5.6 x 4.4 cm
This really interesting piece shows clear, vibrant inclusions of pyrite INSIDE of the quartz crystal. (some breach the surface so the could be analyzed). It is an unusually large and elagant quartz piece for the locality by any standard ! The crysat is draped with white dolomite on the top and back. 19.5 x 7 x 5.7 cm
This impressive specimen is a rare mineral from the locality, though a common species from elsewhere. Good pyrites from Panasqueira should be as trasured as anything else from this important locality, and this one will add to the breadth of any Panasqueira collection 9.2 x 8.5 x 6.2 cm
It is just not that easy to find an old Colorado pyrite with the top quality of a good Peruvian specimen, but this one qualifies. Super-bright golden crystals to 1.4 cm, with pretty striations, on BOTH SIDES of the specimen. Much brighter in person! This is a killer....It came to me from a respected Denver dealership, as well, so i am confident of the locality data 8.4 x 5.9 x 3.5 cm
What more could you ask for in an old Butte pyrite? Beautifully sharp, lustrous, striated crystals piled on one another. Rare in this quality! 4.4 x 3.2 x 2.6 cm
