Vintage 9K Gold Plated Hoop Earrings With Deep Pink Ruby- Like Stones

Vintage exotic hoops earrings. With prong set deep pink and clear stones. The red ones look like rubies, but could be crystals or art glass. The clear ones are either colorless sapphires, or crystals. Stamped with what looks like 9K. I think they are 9 karat gold plated because of some signs of wear exposing silver tone metal underneath.
