Sterling Silver Marquisite Faux Pearl Ring Cocktail Ring

Size 6 1/2, sterling and marquisite statement ring. I can't find the 925 marking, but I bought it in NYC at a wholesale jewelry store specializing in sterling jewelry. It's stock from a retail space I closed. It rises 3/4" off the finger. It's set on a post between appearing to be held by four marquisite set prongs.
