Brazilianite

Brazilianite is an uncommon and unusual gemstone. Cut for collectors only, its yellow or yellowish green colour is nonetheless striking. Crystals are fragile and brittle, with conchoidal fracture and perfect cleavage perpendicular for their length.
The primary localities have been in Brazil, where crystals as much as 15cm (6 inches) have been discovered. Smaller crystals happen to be mined in Nh in the united states.
Present in Minas Gerais in Brazil in the mid 1940s, brazilianite was initially regarded as chrysoberyl, but closer examination revealed that it is a brand-new mineral. It had been named following the country by which it had been found, but has since been wrongly identified as chrysoberyl, beryl and topaz.
