VINTAGE 10k Gold Amethyst & Diamond Tiny Pendant

Vintage tiny amethyst and diamond 10k gold pendant Stamped 10k and SR on the back of the bail This was a gift from my father around my 16th birthday, I think. Amethyst is my birth stone, and I’m guessing the diamonds are real but they are very tiny. Worn maybe once as it has never been my style. No chain.
