Trolleite Heart from Brazil - B

Trolleite is a blue mineral named after Hans Gabriel Troll-Wachtmeister, a Swedish chemist. It is a rare phosphate mineral that is often found with Quartz and sometimes combined with Lazurite and Scorzalite, which results in an even bluer crystal. New discoveries of Trolleite are coming out of Brazil recently, in gorgeous shades of blue, grey, and black.
