Winton, Queensland, AustraliaHand-crafted in Idar-Oberstein, Germany This unique hololith ring is comprised of a natural boulder opal from Winton. Unusual for the presence of opalization on all sides of the specimen, vivid blues and greens contrast dramatically against the natural brown ironstone matrix, with a thoughtfully place concave area to allow for placement on the fingers without pressure. The interior of the shank is lined with a thick inset of 18K yellow gold for comfort and durability. Size 9
