8.1 x 5.9 x 5.2 cm. If you can get past the fact that they are "just" pyrites, you have to admit that these PERFECT cubes on matrix from Spain are amongst the most striking crystals in the mineral kingdom. Non-mineral people usually cannot believe that they form naturally, in fact! This is a LARGE, PRISTINE cube, wonderfully isolated and fully exposed on the matrix. It measures 2.5 cm on edge and has a mirror-golden luster. A fabulous-looking specimen!
4.9 x 1.9 x 1.4 cm. This glassy (in person) quartz crystal is decorated with colorful little crystals of iridescent pyrite, as well as micro lavender fluorites, with a really beautiful result!
5.4 x 4.9 x 4.8 cm. Pretty, lustrous, translucent and frosted, purple fluorite cubes to 1.5 cm are nicely set on contrasting white matrix and beautifully complimented by lustrous, brass-yellow pyritohedrons on this showy and fine specimen from the famous and historic San Martin Mine of Zacatecas, Mexico. This ancient mine is still operational after 400 years!
2.9 x 2.3 x 1.8 cm. This would be "cute" for Peru, but this is actually a Spruce Claim specimen, which makes if far more interesting and desirable! Here you have a super shiny golden compound crystal of pyrite spiked atop a gemmy quartz crystal! The pyrite contact is all on the back, so you have this marvelous display face.
8.4 x 6.4 x 2.9 cm. This Eastern European specimen looks like a pile of bright gold sitting in a nest of fine quartz crystals! These pyrites are just so bright and pristine, with pretty striations on their faces. The contrast with the silky, slender and elegant quartz crystals is gorgeous. Remember, this is not the much more common Peruvian material!
6.0 x 5.4 x 3.7 cm. An imposing specimen of totally gemmy, light sea-green, cuboctahedral fluorite crystals. Some crystals have distinct, stepped-growth faces and the scattering of included pyrite crystals is a very nice accent. Many of the cuboct crystal faces are lightly frosted, but some are water-clear, giving a neat television-like view in to the crystal interior. From the recent find at Naica. Classic material.
3.3 x 2.1 x 1.9 cm. A REALLY CUTE and NIFTY GEM danburite crystal from Charcas, Mexico. Two pyrite crystals are perfectly aligned within the complex termination of this water-clear, colorless danburite. You see the two pyrites in the front of the crystal, but you see Five on the back, due to the multiple crystal faces! This is a nifty crystal with character!
10.1 x 9.9 x 5.5 cm. A large specimen from a pretty and unusual find in China about 2 years ago, of calcite crystals whose edges are covered with a bright golden, melty-looking pyrite! Unique material and beautiful as you can see!
7.6 x 6.1 x 5.9 cm. If you can get past the fact that they are "just" pyrites, you have to admit that these PERFECT cubes on matrix from Spain are amongst the most striking crystals in the mineral kingdom. Non-mineral people usually cannot believe that they form naturally, in fact! This is a LARGE, PRISTINE cube, wonderfully isolated and fully exposed on the matrix. It measures 2.5 cm on edge and has a mirror-golden luster. A fabulous-looking specimen!
7.8 x 7.5 x 4.9 cm. If you can get past the fact that they are "just" pyrites, you have to admit that these PERFECT cubes on matrix from Spain are amongst the most striking crystals in the mineral kingdom. Non-mineral people usually cannot believe that they form naturally, in fact! This is a LARGE, PRISTINE cube, wonderfully isolated and fully exposed on the matrix. It measures 2.7 cm on edge and has a mirror-golden luster. A fabulous-looking specimen!
6.0 x 5.7 x 5.2 cm. Here is one of the more interesting new finds from the last few years in Bolivia. Typically, Bolivian Pyrite is not found in attractive, displayable, well-crystallized specimens. This however is one of the better specimens from the lot that I purchased and is very aesthetic and attractive. The specimen has a beautiful display side which is loaded with dozens of octahedra modified by trapezohedra which is a rather uncommon crystal habit for this rather common sulfide. The largest crystal measures 1.0 cm across. All the Pyrite crystals are extremely bright and shiny. This is good display specimen with great aesthetics. It is definitely one of the more unique locality names in the mineral world as well! Ex. Brian Kosnar.
5.5 x 4.2 x 3.3 cm. A gemmy and lustrous, sharply hexagonal, 5 mm, blue apatite crystal stands beautifully upright in the middle of a rich field of enargite, highly lustrous, brassy pyritohedrons and needle quartz on this showy and excellent, old-time combination specimen from Butte. This VERY FINE combo piece is probably from the Leonard or East Colusa Mine. Ex. John Ydren Collection.
8.4 x 5.7 x 3.4 cm. An old Butte pyrite with PERUVIAN quality -- though a whole lot harder to come by. These mirror-bright octahedra with flat tips are isolated on a field of grayish quartz crystals. Ex. John Ydren Collection. Super for this old classic locale.
10.2 x 8.2 x 4.9 cm. If you can get past the fact that they are "just" pyrites, you have to admit that these PERFECT cubes on matrix from Spain are amongst the most striking crystals in the mineral kingdom. Non-mineral people usually cannot believe that they form naturally, in fact! There are three crystals here, the largest measuring 1.5 cm along the edge - in a nice balance across the matrix.
7.3 x 6.3 x 6.1 cm. From the Hauck Collection, a LARGE and striking example of this Utah phenomenon - goethite that has pseudomorphed a complex compound crystal of pyrite, to form a beautifully sculptural specimen that looks like modern art (with an antiqued bronze patina, even)!
