Sphalerite with Chalcopyrite
stock #7-TRI-578
Tri State District, Ottawa County
Oklahoma, United States
15 x 9.7 CM (cabinet)
price: $500


A very old and very fine Tri-state classic! Ex collection of the Arizona-Sonora Desert Museum, This is a true top shelf specimen. Sphalerites here reach to 4 CM and are exceptionally well formed. The smaller crystals are a fine ruby red (rubyjack) while the larger ones are darker and coated with chalcopyrites. Some faces are noticably irridescent and over all the luster is outstanding. The only damage is at the outer edges where it would be expected, the display face is pristine, three dimensional and very esthetic. The old Tri-state area produced a lot of materials in its time, but this quality was excellent even in its heyday.
