Cubic and crystallized pyrite matrix with Marmatite and Quartz crystal cluster.
Some of the more important Colorado localities for specimens of well-crystallized pyrite include mines at cli- max, Gilman, Leadville, Rico, Ouray, Telluride, Creede, Alicante, Alice, and State Bridge. Specimens from each of these localities often have distinctive crystal habits and mineral associations. The Eagle mine is probably best known for its pyritohedral Pyrite specimens. This cluster is a good representative Eagle mine Pyrite showing typical striated pyritohedra with sharp, lustrous faces plus some Marmatite opaque black iron-rich crystals.
This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

Tiger's Eye typically exhibits a rich golden to reddish-brown color with a silky luster. The distinctive chatoyant effect resembles the movement of a cat's eye, giving the gemstone its name.

With a hardness of 6.5 to 7 on the Mohs scale, Tiger's Eye is a durable gemstone that can withstand everyday wear: however, it can still be susceptible to damage from harsh chemicals or extreme heat.

Pseudomorph Goethite After Marcasite | Prophecy Stone | 17-23 gr | Farafra Oasis, Egypt
You will receive one of the Pseudomorphs pictured.
Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another. The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.
The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.
These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition. This collector's specimen is unique, of great quality and ready for display.
