Red Stone Cocktail Ring Square Crystal Accents AD 925 Sterling Silver Size 9.75

A silver cocktail ring with a rectangle red stone in a halo of clear accent stones. I'm unable to identify the stones. It has a stamp but it's hard to read, looks like it says "AD 925". It weighs 6.90g and is a size 10. In excellent condition, please review photos closely.
