Silver and marcasite earrings

I am selling this fun pair of genuine marcasite earrings, tiny opaque teal stones in silver settings. One earring's setting is noticeably darker than the other - it doesn't appear to be tarnish. Settings have tiny sparkly facets that glint when they catch the light. Earrings are approximately 18mm in diameter and dangle approx 33mm. Weight is 4.64 grams. in excellent pre-owned condition - offers welcome!
