GIA Certified 2.88ct Paraíba Tourmaline Diamond Platinum Ring

A GIA-certified 2.88 carat natural copper- and manganese-bearing tourmaline, the variety known in the trade as "Paraíba tourmaline," set in a platinum three-stone ring with a cushion-cut center flanked by tapered baguette diamond side stones. GIA identifies the stone as a copper- and manganese-bearing tourmaline of Nigerian origin; per GIA, such stones "may be called 'paraíba tourmaline' in the trade," a name originating from the Brazilian locality where the gem was first mined, though today it is sourced from several localities. GIA designates the color as Green-Blue with Transparent transparency, the glowing blue-to-teal appearance that makes Paraíba tourmaline one of the most sought-after colored gemstones. The GIA report does not indicate any clarity treatment. Buyers are encouraged to review all photos carefully before purchasing.
