A large lustrous specimen of an Aussie Crystal Molybdenite. There is no matrix to speak of, it’s all crystal. Hard to find in this size. Molybdenite is the main ore of the metal molybdenum. A great addition to your metals collection. Some are using specimens like this Molybdenite Crystal as a power transistor by slight modification in the lab. The Yellow oxide on the back of this specimen is a good indicator of Bismuthinite. This specimen was difficult to photograph due to the metals high reflection.

Molybdenite is a very soft metallic mineral. It can be easily confused with graphite, but not with many other minerals. Graphite has a darker black silver color and a black to gray, brown to gray streak, whereas Molybdenite has a bluish to silver color and streak. It is soft enough to leave a mark on paper and fingers. The greasy feel is due to extreme softness. Molybdenite or “Moly Ore” as it is sometimes called, is a very high luster mineral and is an interesting mineral to add to your collection.
