Modernist Sterling silver and gemstone ring

An awesome modernist ring in sterling silver and featuring mystery stones: moonstone and tanzanite, perhaps? Either way, its geometric angular form is modern and chic. It is marked for sterling on the back, along with an artist mark: “SK.” It is approximately size 7. This ring has lovely patina and glows like only a well-loved piece does. It was clearly someone’s favourite! Will it be yours? Follow along with all of my vintage finds on Instagram @ShirleyToGoodnessVintage 🤍
