Vintage 1930s Onyx Marcasite Black Inlay Sterling Silver Ring, Sz 6-7

Vintage Heirloom Women’s or Men’s Sterling Silver Black Inlay Ring with Center Pear-Shaped Onyx, Black Inlay (presumably onyx or bakelite), and 15 Marcasite Stones. Cigar band style, comfortable rounded interior finish on band. Maximum width of band is 3/4 inch, central onyx is approximately 1cm in length. 925 stamp on interior. This will fit sizes 6-7 (interior diameter is 17mm), can be worn by women or by men as a pinky ring. Provenance and date of purchase unknown, this ring belonged to my grandparent or great-grandparent in the 1930s. Ring has been cleaned carefully of tarnish with silver cleaner, but there are minuscule flaws in the inlay that occur naturally with such a difficult process. Please see photos for full 360 view. Feel free to inquire more about dimensions and pictures. This ring is one of a kind.
