Stunning 10K Gold Garnet Heart Screw Back Cluster Earrings Germany Antique Vintage. Total weight is 3.3 grams. Stones have not been tested, and I'm not a jeweler, so it is my opinion, but not a guarantee, that the stones are garnet. Each earring measures just under 1/2" at widest--7/16". They have beautiful color and tons of sparkle! See pictures for details as all sales final and as is.
