Margaret Elizabeth's Black Druzy Stud Earrings are a go-to style for everyday. The natural black druzy with its organic finish contrasts nicely with the high polished gold vermeil.  Druzy is a natural stone in the agate family. It is a layer of crystals that forms within a mineral crust, giving it that subtle, gorgeous sparkle.
