Vintage Sterling Silver Red Rose Portrait Earrings

Vintage Sterling Silver Red Rose Portrait Earrings. Bought from a local second hand store. Purchase does not include black earring holder. These earrings are marked 925 sterling silver and have a markers hallmark I cannot identify. The stones do not register on the Diamond tester so I assume red rhinestones or garnets and the flowers being covered in enameling. These are beautiful earrings with a hammered back design. The attachment is a hook design. The earrings are tarnished so they may need a polishing unless you like the antiqued portrait look which I do. Happy buying and I do accept best offers!
