Gabrielle Sanchez Rutilated Quartz Flyer Earrings in 18K Yellow Gold. Hand-made findings made from 18K yellow gold secure 14MM faceted rounds of rutilated quartz, a natural gem created when molten quartz flowed around tensile material in the earth's crust. The result is a shimmery product that gleams with metallic gold, warm brown and beige. Hinged, lever-style closures snap into place allowing comfortable wear all day. For pierced ears.
