This pair of earrings are in sterling silver with sterling silver lever-back attachments. I have shown the mark on the levers, but the marks on the earrings are impossible to photograph. They read "925 copyright (M)" and are located on the inner edges of the earrings. These mountings are cast but hollow, making them not too heavy to wear. The workmanship is excellent. The bezel set cabochon stones are lapis lazuli with visible flecks of gold. These earrings are around 20-25 years old. They are in excellent original condition. The drops measure 3/4" X 5/8" X 1/4" thick and weigh 6.7 grams.
