Sweet Australian opals are wrapped in 22k gold and sit on a circle of 18k gold and silver bi-metal*. I've added a lush cluster of exceptional pink sapphires below. The ear post is 14k gold and secure with a silicone earnut for comfort. These measure 1/2" in diameter.
*Bimetal features a layer of 18-karat yellow gold pressure-bonded to a layer of sterling silver. 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.
