Roberto Coin Three-Circle Ring from The Tiny Treasures Collection. 18k White Gold with 42 round brilliant cut diamonds. No stones missing. Ring is in pristine condition. Retails approx $1,860.00. Size 4, can be sized up. No paperwork or original box included. Authenticated by Poshmark. PRICE IS FIRM. ** This ring is from a discontinued collection by Roberto Coin, and is a rare find. It was gifted to me as a new ring directly from a Jeweler, I just can’t find the paperwork. Although it is absolutely stunning, I only wore it less than a handful of times.
