Sterling and Marcasite Necklace 925

This necklace is comprised of five circles in different sizes. It is marked 925 on the clasp tag and is 16 inches long. The main circle in the middle is approx one inch long. When you look closely at that biggest circle in photos, two of the tiny jewels are missing but it's not noticeable when wearing. It has only been worn once and has been stored in drawer.
