Return to Main Minerals List

Heubnerite is a dark reddish-brown submetallic to resinous mineral that forms monoclinic long
prismatic striated crystals. It may occur granular massive or bladed and simple contact
twinning is common. Heubnerite is a heavy mineral that is somewhat soft and slightly
transparent. The deep red color is best seen at points where the crystals have been broken or
chipped and viewed in a bright light source or natural sunlight. This mineral may be found on
matrix with Casserite, Quartz, Fluorite, Tourmaline, or Topaz to name a few. Heubnerite was
named for Adolph Heubner, a metallurgist of Freiburg, Saxony. The best specimens of this
mineral tend to come from Colorado or Peru.
