Looks like the real gemstone! The designer created a triangle with charcoal grey, almost black, faceted crystal around a center of clear faceted stones. Each of the charcoal grey stones are approximately ¾ in carat weight and the clear faceted stone are ¼ in carat weight. So there are lots of beautiful sparkle in these earrings.
The backs are polished silvertone with clip backs that are in excellent working condition.
Measurements are approximate: 1 5/8” on all sides.
