“8.6 x 8.0 x 4.3 cm. Summitville, Colorado covellite of this quality is rarer than Butte covellite and is considered by many to be the finest covellite in the world. This striking, large, upright, two-sided specimen features large, intergrown metallic plates of iridescent, golden-bronze, magenta, and peacock-blue covellite on all sides. The blades reach 4.8 cm and the large magenta blade is striking. Solid covellite, this is an outstanding example of the species and famous locale.
