Two splendent prism faces of the submetallic crystal have beautiful dense filigrees of cherry-red color under bright light. The other two prism faces appear to be contacted and both ends are broken. It could be RARE ferberite, but the specimen has not be analyzed. The chunk of included quartz adds character. Hefty ore at 213 grams mass.
