Enamel Butterfly Ring - Sterling Silver - Opro

Huge rare Opro Enamel sterling butterfly ring.  These were made a few years back and they are very rare.  The enamel is gorgeous and the size is much larger than other butterfly rings I’ve seen.  Butterfly measures just under 1.5 inches across at widest point.  Band is adjustable.  Currently approx size = 8.  Stamped Opro (company in Norway) and 925.  Butterfly is slightly tilted in the setting to appear as if it just landed on your hand.
