Tourmalines
Paraiba tourmalines are among the rarest gemstones on earth — prized for their extraordinary neon blue-green electroluminescent colour, caused by trace copper content. We occasionally access verified African Paraiba stones, each accompanied by a GIA report confirming origin and copper-bearing composition.
