A rare, classic ullmanite from this important locality! It is not the type locale, but is probably the more famous as many fine specimens were collected here in the early to mid-1800s. Recently, some friends of mine have reworked these old mines and found a few specimens I was happy to get. This is one of the more dramatic and showy, featuring bright, starkly cubic ullmanite crystals (to 4mm) on contrasting calcite. I have not seen good ullmanite for sale in 4-5 years, now, so this is a good chance to grab one! Also, the piece is very richly covered, as a bonus.
