These round gold hoops are persistent and steadfast. Their love and loyalty is material for myth. They demand to be out and about but are unmoved by frequent admiring glances. The surface is polished for a luminescent shine. They are made of 14K gold: pure gold is too malleable for jewelry and so is mixed with alloys to add strength and durability. While yellow gold is mixed with silver, copper and zinc, white gold is alloyed with nickel, copper, and zinc. The posts are on a hinge and snap into a "U" shaped fixture on the back of the earringforever relieving worries about lost earring backs and, in turn, lost earrings.
