The piece shows sharp, flat-laying, acicular crystals of Amarantite in sprays to perhaps 5mm. In person, these crystals have a robust, electric orange-red flare to them and are quite eye-visible. Mixed in (close-up photo) are small tufts or ball-shaped clusters of microcrystalline Hohmannite. Associated minerals are Metahohmannite, Kornelite , Chalcanthite, Copiapite, and Picromerite, I am told.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",747,{"id":215,"source_url":216,"license_code":178,"credit_html":217,"title":218,"description":212,"author":191,"original_width":200,"original_height":219},1040,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10149607","Robert M.
