A classic Hubnerite specimen from the Adams mine in Colorado. This mine is essentially known for these specimens specifically, but they are still among the best and most popular for the species from all of Colorado. Several beautiful, sharp, lustrous, deep brownish-red, tabular striated crystals of Hubnerite sit atop a granular Quartz matrix. The largest Hubnerite crystal measures 2.3 cm long. The piece was mined by San Juan miner Max Gallegos in 1971. Specimens such as this are not readily available these days. Ex. Richard Kosnar Collection.
