Size 8 sterling silver nugget design with a natural oval topaz. The topaz is sometimes called "opal topaz" or "mercury mist". It is similar to mystic topaz as the color is the result of a surface coating that produces beautiful opalescent colors. Measures about 12-13mm across the finger and weighs 7.6 grams. Great unisex ring and would make a perfect man's pinky ring too.
