About Stichtite

A stichtita é um vívido mineral de hidróxido de carbonato de magnésio e crómio de cor lilás a púrpura com um lustre ceroso a perláceo que ocorre frequentemente com serpentina verde para formar a pedra ornamental denominada atlantisita. Extraída principalmente na Austrália (Tasmânia) e na África do Sul, é muito apreciada em cabuchões e objetos esculpidos pelo seu contraste de cores entre o lilás e o verde. A sua raridade relativa e cor incomum tornam-na uma pedra de colecionador muito procurada.
