(size 8.25, can be made larger not smaller) This large, amazing Boulder Opal from Australia looks as though you could dive into it...it looks like a ridge in the ocean that goes from shallow to deep water, really a rare find. Flashes range from iridescent purple, to blues to greens, depending on the direction. Set in sterling with 22K gold accents, the band is round and 10mm wide with gold accents. It is a visually large ring measuring 1-5/8" long by 3/4" wide. PLEASE SEE ALTERNATE VIEW FOR SCALE! Will accept returns with 5 days of receipt.
