Purple spinel with pink sapphire accents signed 925 earrings please read

These are synthetic amethyst purple spinel sterling silver with a pink sapphire accent stone. Marked and tested 925 designer signed sts. These are selling for a little cheaper because one of the earrings backs doesn't snap into place its got a little damaged in transit to me. It still works fine you just have to guide it into place. I'm willing to change them to sterling hooks but didn't want to do that unless wanted. Alternatively a jeweler might be able to fix. Gorgeous earrings. New with tag.
