Australian Opal and Diamond Ring set in 14kt yellow gold. The centerpiece is a single pear-cut Australian white opal measuring approximately 14 x 10 mm, surrounded by 10 round brilliant diamonds with a total weight of 0.12 CTW, VS2 clarity, and near-colorless I color. All 11 stones are set in a warm yellow gold band.

Available in ring sizes 5, 6, 7, and 8, and sizeable within one size (Costco does not provide sizing services). All diamonds offered by Costco are natural and untreated. Colored gemstones are often enhanced in the production process unless otherwise stated. Opal is the birthstone for October.
