No mold used! Size 14 (ish). The band was hand built for larger fingers. Can not be worn ambidextrously (the same way on both hands) but a simple twist allows it to be worn on the left hand and creates the illusion that it's a whole different piece. Individual pieces of sea glass hand placed and cured (UV light). A truly one of a kind piece, un-reproducable due to the nature of naturally made sea glass.
