These AA grade Herkimer Diamond apple drop earrings have so many beautiful components. Tiny Herkimer Diamonds have been incased in a 10mm glass apple globe which dangles from a sterling silver ear wire. These ear wires are sterling silver with just a touch of rhodium added to prevent, or at least delay tarnishing. Herkimer Diamonds are quartz formations which because of their brilliance and diamond shape have been given the name. Mined only in Herkimer, NY. Herkimer diamonds help release energy blockages and also help enhance dream recall. Really nice!
