Vintage 925 sterling silver flower shaped earrings with pink ruby stones

Vintage sterling silver stud earrings. Handmade. Stamped 925. Shapes like flowers. With marcasite stones and round ruby color stones, not sure if these are natural or lab created rubies. The backs are brand new, not original, made of silver tone metal that looks like not sterling, possibly hypoallergenic stainless steel. One ruby stone is a bit off-center, as pictured, but this is not too noticeable. Also, the posts are quite long, as pictured.
