Costume Ring with Ruby Glass Stones

This is a small ring, I believe, that is called a “chevron” ring. The little stones have the most beautiful colour! Each little stone looks slightly different in colour and cut. I think there might be a possibility that they are actual real. I won’t, however, take it to a jeweler because the metal is definitely not gold. It’s not brass but maybe some other alloy. There are no markings on the ring.

Thanks for looking:)
