A REALLY GOOD, uncommon, bright brass-yellow pyrite "bar" from the famous Buick Mine of Missouri. Good ones like this came out 20 to 30 years ago, and except for the out-of-sight contact on the back, this one is undamaged. Excellent material from the Lewadny Collection. MUCH BETTER IN PERSON. 7.7 x 4.7 x 4.3 cm
An unusually large, striking pseudomorph of goethite that has replaced pyrite crystals. This floater cluster has a fine antique bronze patina. Looks like modern art! 5.9 x 5.9 x 5.3cm
Very hard to find on the market these days, from an old thumbnail collection, a perfect floater ball of pyrite from the old New York locality of Boulder Creek. 1.8 x 1.8 x 1.6cm
Lustrous, gray, prismatic crystals to 5 mm of the very rare thallium sulfosalt hutchinsonite richly cover pyrite matrix from the famous Quiruvilca Mine of Peru. The orpiment crystal on one end adds character. Ex Richard Hauck Collection. 6.5 x 4.1 x 1.6 cm
Pink apophyllite crystals with finely-formed, bright and striated pyrite crystals. Also note the pretty spherical white tobermorite 3.3 x 3.1 x 2.7cm
A VERY SHOWY, nearly complete all-around, combination sulfide specimen from Concepcion del Oro, Mexico. Mirror-bright, brass-yellow pyrite cubes to 1.0 cm rest in matrix with coated, tetragonal chalcopyrite crystals to 1.7 cm and striated, lustrous, olive-green sphalerite. Trivial damage, overall and with only two small points of attachment. Ex Ed Ruggiero Collection, who purchased this piece in June, 1975 from the Columbine Rock Shop in Ouray, Colorado. 6.7 x 4.5 x 4.5 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. 7.7 x 7.4 x 0.6 cm
An EXCELLENT and showy combination specimen from Bulgaria dominated by lustrous, striated, gun-metal gray chalcopyrite crystals to 1.9 cm with transparent, needle quartz crystals, scattered pyrite and sphalerite crystals and a single, flattened calcite rhomb. Very trivial damage, overall, with only a couple points of attachment. Note old Museum label from an Eastern European institution 6.5 x 5.8 x 4.8 cm
Three pristine balls of super-sparkly pyrite from Germany, very hard to obtain now, and really unbelievable in their perfection. Show these to any non-collector and tell them that they form naturally like this, and you will get quite a reaction. Nothing quite like these old German pyrite spheres - and just try to find some out there somewhere! 0.9 x 0.9 x 0.9cm, 0.9 x 0.9 x 0.9cm, 1.3 x 1.3 x 1.3cm
Elba Island is famous for good pyrites and hematites, both represented here in a fine combo specimen. The pyrite crystal measures 2.5 cm across, and is perched atop a matrix of massive hematite. This is an extremely well-balanced, unusually fine miniature specimen! 5.4 x 4.8 x 2.4cm
One of several SUPERB large pyrite specimens that came out of the recently-dispersed collection of Paul Jung. These are mirror-bright modified octahedrons, to 6.5 cm along the edge, with pretty cut-glass-like modifications on the faces. There are your basic pyrites, and then there are those rare ones that belong in a fine collection. If you are not jaded about pyrites, you have to admit that a great pyrite is about as eye-catching a mineral specimen as any in existence! 11 x 7 x 6 cm
Recently we offered a couple of pyrite balls from this old German find. This is an elongated and "interesting" shape, a floater, with the same fine sparkly luster. These are very hard to obtain on the market today! 3.4 x 2.9 x 1.5cm
A rich, dramatic cluster of mirror-metallic, golden pyrite octahedrons, with the larger crystals (to 2.5 cm) perched perfectly at the top of the specimen. In person, the crystals are a much richer gold than they appear in the photos, and the mirror brightness of the crystals is just astounding. Mediocre pyrites are common, but the really good ones are not! 14.4 x 7.9 x 4.6cm
One of two very fine Peruvian pyrites in this auction, from different mines. This is a sharp cluster of octahedrons, the largest measuring 4 cm tip-to-tip. The cluster is flat on the bottom where removed from the pocket, and sits up beautifully all by itself, with the big crystal canted at a perfect angle. GORGEOUS and better in person! 5.3 x 4.2 x 4.1cm
A STRKING and EXCELLENT CABINET specimen of nests of lustrous, soft, hair-like, silver boulangerite crystals richly covering the upper-half of the arsenopyrite, pyrite and quartz matrix from the famous Noche Buena Mine in Zacatecas, Mexico. Ex Ed Ruggiero Collection, who purchased this piece in 1975 as jamesonite, but had it x-rayed as boulangerite. The arsenopyrite crystals are also choice and are up to 7 mm. 12.2 x 7.0 x 5.4 cm
