Dumortierite in Quartz Marquise on Swirled Band. Size 7 3/4.

This mesmerizing quartz has sky blue dumortierite inclusions that appear as delightful sprays in the upper and lower portions of the stone. I've set it on a base of 22k gold and silver bimetal* and wrapped it in a bezel of 22k. The swirled band of argentium sterling silver is dotted with gold. This band fits like a 7 3/4. *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.
