These are real stunning Native Telluric Iron fossil minerals, with verified purity up to 99.99% (four nines)! This level of pure elemental iron is virtually unheard of in nature, and nearly impossible to replicate artificially. That makes each piece exceedingly rare and valuable.These specimens may also contain natural inclusions of Platinum Group Metals such as rhodium, iridium, palladium, nickel, or copper, formed during unique terrestrial transitions. Each nugget is a geological masterpiece. You?ll receive roughly a 3 gram mineral or more in its natural formations as a pretty nugget, metallic bleb, fine leaf or T twinkly plate. They have a rare silvery-white luster. Also they have a soft, malleable, or ductile texture making it a great Ideal for high-end jewelry making, and electronics without any further surface modifications.
