Vintage 925 sterling silver flower shaped earrings

Vintage handmade sterling silver stud earrings. 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 and made of silver tone metal that is not sterling. One ruby stone is a bit off-center, as pictured, but this is not too noticeable.Also, the posts are quite long and may be suitable for larger earlobes.
