Vintage Sterling Silver, Marcasite, Onyx, & Mother of Pearl Cameo

Vintage pin. Pin marked 925 A. This is sterling silver with Marcasites. Cameo silhouette. The center is black onyx with a mother of pearl cameo. Good used condition. Pin isn’t perfectly straight. But it not bad. The center cameo does wiggle just a little in its setting, nothing to bad, moves maybe 1/16”-1/8”. No missing Marcasites. I polished this a little but didn’t get into the grooves, because I felt the darkness gives it contract and interest. You can wear this as a pin or pendant. Older item, it may show wear due to age, use and storage. Unknown maker. Approx 2” x 1 7/16” Weight shown is approx.
