Vintage Iris Earrings. Cerulean druzy disks with 14k gold-filled fish hooks pair perfectly with our matching Pluto's Satellites Necklace. Druzies are naturally occurring crystals that form on top of other gemstones like agate and resemble sugar. They can be any shape or color, even black, and they sparkle like glitter in the light. The 1.125-inch Iris Earrings are the go-to earrings to give bright pink, yellow and floral tops an extra zing.
