An amazing, first class loose natural green tourmaline gemstone of the highest calibre. The vivid verdant green is simply divine and the tourmaline gem has been precision cut and polished in a classic square cushion design with an Asscher style stepped pavilion. This makes it a very unique gemstone with a distinctive look. It is a knockout stone, big and beautiful and would make the ultimate cocktail ring for that special occasion. Truly superb loose natural green tourmaline gemstone.
