An historic, exceedingly rich and showy specimen of mercury ore from the New Almaden District of California. Two faces of the sculptural, brecciated dolomite matrix are richly covered with lustrous, blood-red cinnabar microcrystals. The third side is totally covered with brick-red cinnabar, in microcrystals or in massive form. Seldom seen in this richness. Accompanied by two, old labels. R.M. Wilke was a prominent California mineral dealer from 1907 to the early 1940s. He died in 1946. Ex. Hageman and Mullane Collections. For what this is, a historic specimen from a mining district of huge industrial import at the time, this is a nice relic.
