A lustrous, old-time, LARGE, brassy pyrite cube from Leadville, Colorado. This is a classic Leadville piece with overgrowthed and striated faces and comes with large, old, faded label. This piece must be at least 100 years old. Ex Richard Hauck Collection and also with label from teh Crunden Collection at Harvard 6.5 x 5.2 x 4.9 cm
A really aesthetic and superb plate of bright, shiny, tiny pyrite crystals surrounded by larger pyrite cubes to 1.0 cm from Dallas-Ft. Worth Airport in Texas. This locality is now extinct, as runway expansion obliterated the stream bank, where these were found in a shale layer. Ex Ed Ruggiero Collection, who purchased this piece in April, 1975. 6.8 x 4.9 x 1.4 cm
A HIGHLY UNUSUAL, lustrous, undamaged, floater pyrite ball from an uncommon, old Tri-State District mine. Ex Richard Hauck Collection. Never seen these before! 1.8 x 1.7 x 1.7 cm
An EXCELLENT, old-time Leonard Mine combination piece dominated by lustrous, striated enargite prisms to 1.4 cm with nicely contrasting needle quartz crystals and lustrous, brass-yellow pyritohedrons on massive pyrite matrix. The major enargite crystals are pristine and the minor periphery damage is certainly not detracting. 6.9 x 5.7 x 3.5 cm
I can''t say enough about the gorgeous crystallography expressed in this specimen of pyrite. The isolated, smaller single crystal at the edge of the specimen could be in a textbook for its formal perfection''; the hexagonal faces on this dodecahedron are perfectly symmetrical. The other crystals are highly modified and wonderfully architectural. All the crystals are beautifully isolated on the matrix of sparkly quartz crystals. Yes, there is a lot of mediocre pyrite out there, but really good specimens such as this remain highly desirable. 7.1 x 5.1 x 4.5cm
Very attractive, nearly complete highly modified single crystal of Pyrite. What is remarkable about this pyrite is that the larger faces have a center zone of brilliant luster with the faces rimmed by a zone of ‘brushed’ luster. This may not be unusual for many minerals, but I have never seen this before on a pyrite. This makes it a unique and attractive specimen. 1.5 x 1.4 x 1 cm
How often do you find a Pyrite that has survived Tsumeb? They were very rare, there. The striations and patina on this mostly complete set of intergrown crystals is truly stunning. A beauty of an unusual Pyrite. 1.5 x 1.3 x 1 cm
17.5 x 17.3 x 15.7 cm. A heavy, really fine pyrite specimen that is of a quality one seldom sees. The large crystals are all sharp and undamaged, and possess a second generation overcoat that adds millions of points of sparkling reflections to the surface. Each is 2 inches or more in size. The whole cluster is actually complete-all-around, 360 degrees. Ex. Smithsonian Institution Collection.
Complex intergrown cubes that are highly modified by stepped growth on most of the faces. Excellent luster and good brassy color. 3 x 3 x 2.4 cm
Beautiful set of three modified pyritohedrons (largest to 1.3 cm!) looking like your classic water molecule. With such good luster, form, and aesthetics, this is well above your average pyrite specimen. And look at the location! 2.7 x 1.9 x 1.2 cm
Here is one of the more interesting new finds from last year in Bolivia. Typically, Bolivian Pyrite is not found in attractive, displayable, well-crystallized specimens. This however is one of the very best specimens I''ve seen and is very aesthetic and beautiful. The specimen is virtually undamaged on the display side and is loaded with dozens of trapezohedra modified by octohedra which is a rather uncommon crystal habit for this rather common sulfide. The largest crystal measures 1.2 cm across. All the Pyrite crystals are extremely bright and shiny. 16.0 x 7.8 x 6.8cm
A sensationally pretty Eastern European specimen. These pyrites (to 1.8 cm) have the most gorgeous luster, striated faces and modified edges - but more than that, it is the way they are nestled amongst these very distinctive-looking Madan quartz crystals, which don''t look like quartzes from anywhere else; they have a very unique beauty to them. 10.8 x 6.8 x 5.4cm
A SUPERB and AESTHETIC cluster of three, mirror-bright, brassy, pyrite cubes to 2.9 cm beautifully set in clay matrix from Navajun, Spain. A couple of trivial edge bruises certainly do not detract from this stunning piece, which can be viewed from many different angles. 6.9 x 6.8 x 4.5 cm
An old classic Butte enargite with fine, sharp crystals to 2.5 cm, distinguished by bright little pyrites which decorate the sides of the enargites. A very 3-dimensional cluster that is interesting from all sides, with just a bit of matrix attached. SUPERB freestanding xls for the locale! 4.2 x 3.5 x 3 cm
Yes, pyrite is common, but the very fine ones such as this are still HIGHLY desirable! This specimen has the best mirror-metallic, golden luster, and its form is beautiful: sharp modified octahedrons with pretty bevels along the edges! That big crystal measures 6 cm across! This piece has a spectacular display face, with the contacts only on the back and bottom. 7.5 x 7.2 x 5.5cm
