GEM: 6 x 4 x 4 mm and 1.35 carats A matrix specimen featuring an extremely fine small crystal of this classic deep blue, unheated, natural indicolite that once set the standard for blue hue in gem tourmalines. I am told these came out befor eBrazilian indicolite was common, and still set the standard for a"pure" blue. Faceted stones go for $300-500 per carat and this rough and cut set is of top quality (the crystal could be easily cut, itself). Includes a matching cut stone from the same rare old material.
