This specimen has a beautiful large pyrite cube that is mostly exposed from the matrix, and a smaller, complimentary cube exposed on the other end of the matrix. Both are in wonderful condition and have smooth luster. It's hard to believe they are not polished or shaped at all!
Measurements: Specimen: ~4" x 2-1/4" x 3" Crystals: ~1-1/4" and ~3/4"
Location: Navajún, Spain
Pyrite is comprised of Iron and Sulfer, giving it a metallic, golden luster. Although Pyrite is abundant in nature, it is quite rare to find fully defined cubic crystals with the perfection and shine of those from Navajún, Spain, making specimens from that area highly desirable for collectors. Due to the fragile nature of the Pyrite and the surrounding matrix, the specimens are extracted and prepared by hand. They are completely natural - unpolished, unaltered.
