925 Silver Pierced Earrings with Amethyst Stones 1cm x 1cm Marked + Maker's Mark

These 925 silver teardrop earstuds are used but in very good condition. There is light scuffing/scratching from use. It is marked 925. There is what looks like a maker's mark on the earrings and backings but I can't make it out. They measure approximately 1cm x 1cm. They come with a gift box.
