a slice of the Fukang meteorite - But cutting the Fukang meteorite open yielded a breathtaking sight. Within the rock, translucent golden crystals of a mineral called olivine gleamed among a silvery honeycomb of nickel-iron.
Gem quality sphalerite is a rare collector stone. The mineral is usually nearly black in color but is occasionally found in transparent pieces of an orange or yellowish brown hue. Clean pieces are extremely rare.
