Amethyst, green peridot and pink tourmaline earrings set in silver and 18k gold

Pear shaped purple amethyst and green peridot with an oval pink tourmaline earrings set in Sterling silver. Approximately 3/4” long. Purchased by me at an online site and stored carefully in a smoke free home. I’m including a screenshot of the description from when I originally purchased it several years ago. I am not a professional jeweler and cannot verify. Purchased for my personal use and never worn by me.
