A 2.71 carat solid boulder opal displays swirling creams and teals. I've wrapped it in a 22k bezel on a baseplate of 22k gold/silver bimetal*. A cluster of faceted London Blue Topaz rondelles sits at the base of the stone on 14k headpins. Chain is 14k gold and adjusts from 17 to 18 1/2 inches in length. The pendant measures 7/8 of an inch wide, and 7/16 of an inch tall.

*Bimetal features a layer of high-karat 22-karat yellow gold pressure-bonded to a layer of bright Argentium® Silver. The gold constitutes a full 10% of the overall weight and the Argentium constitutes the remaining 90%. The front of the piece shows the gold layer and the back is silver. This is a cost-efficient way to achieve the warm look of gold jewelry.
