NEW Sterling Silver and Druzy Pierced Earrings

New sterling silver and druzy pierced earrings. I was told, when I purchased these, that they are real druzy but I don't know how to test for that. Purchased from a reputable seller on Etsy. They are pretty and the colors are predominantly purple and blue. The purple isn't showing much in the photos but there is purple that flashes beautifully. Approx. 1-7/8" long from the top of the ear wire. The ear wire and frame around the earrings are stamped 925. New, never worn.
