Tiger Eye Clip Earrings Signed Friendship Vintage Gemstone USA Beadrage

This is a unique set of genuine tiger eye clip earrings. I've tried to identify the signature but found nothing about a company call "Friendship" over the years so I'm giving up. Their bequtiful - the tiger eye is pristine - the clips are tight with the original pads however I will also include a new set of comfort pads. They measure1" across - perfect size for day or evening wear. Tiger’s Eye is an amazing fortifier of the blood and exceptional at balancing out the endocrine system. It's also my birthstone so I have alot of it. Mint condition never worn
