Hubnerite on Matrix | 18.2 grams | Ruby Mine, San Juan Co., Colorado | SO24
Hubnerite is a rare manganese tungstate mineral and the manganese-dominant member of the wolframite series. It typically forms dark reddish-brown to nearly black blade-like crystals with a submetallic to silky luster. This dense mineral is an important tungsten ore and is commonly found in high-temperature hydrothermal veins, often with quartz and fluorite. Specimens from Peru and Colorado are especially well known for their sharp, aesthetic crystal formations.
This specimen is in very good condition and displays very well. Make this a special specimen in your collection.
