Large precious opal and diamond ring with a platinum top and 14 karat rose gold shank. The precious opal, measuring 18mm wide by 21.5mm long, radiates its rainbow-like colors in multi-hued iridescence when exposed to different angles of light. This outstanding opal is surrounded by a platinum band holding 26 single cut diamonds approximately .05pt each with a total weight of approximately 1.5 carats. The 14 karat rose gold shank is decorated with an engraved flower on the top of each side and is secured to the platinum top via a series of "wires". Marked 14K on shank with an unknown makers mark that appears to be m.k. Size: 7-1/2; top: width: 23mm, length: 28mm, depth: 5mm. There is crazing to the interior of the opal and the ring is priced accordingly. No doubt the crazing is due to age and lack of proper care. There are no cracks to the opal; the crazing is limited to the interior. Proper care, i.e., saturating the stone with oil or water and storing the ring in moist absorbent cotton, to avoid future aging. Don't be superstitious. The ancients believed the opal brings good fortune to its wearer. Thank you for looking. International buyers please contact me for actual shipping costs to your country.
