This solid boulder opal features sagey green and blue swaths of color across the lower edge and lovely multi-color flashes in the upper portion. It measures 4.8 carats and I've taken photos from several angles to demonstrate the color change and flash. I've set it in a bezel of 22k gold on an oval base of 22k gold/argentium silver bimetal.*

A lush cluster of swiss blue topaz faceted rounds and faceted green tsavorite garnet rondelles on 14k pins sits at the base of the stone. Pendant oval measures 7/8 of an inch by 5/8 of an inch. The 14k gold rolo chain adjusts from 16 to 18 inches with an extender chain.

*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.
