It is covered on the backside with BRILLIANTLY sparkling carpet of thousands of micro-hausmannite crystals and a few little metallic hematites. This combination overall is vastly different from anything else I have seen for the species, and quite unusual in any case.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",{"id":299,"source_url":300,"license_code":118,"credit_html":301,"title":302,"description":303,"author":131,"original_width":304,"original_height":305},72205,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10448400","Robert M.

The matrix is hausmannite and hematite, coated by a rich carpet of soft oyelite.
