This Luna Diamond Eternity Ring In Platinum (3 Ct. tw. - H-I / SI1-SI2) by Blue Nile pairs solid platinum durability with nineteen round brilliant-cut diamonds. Spanning a 3.80mm width, the low-profile shared-prong construction supports three carats total weight of diamonds, exposing their side profiles to surrounding light while preserving structural integrity. Solid platinum offers an unplated, naturally white surface that stays brilliant over decades without requiring re-plating. Designed with smooth, rounded interior contours, this substantial statement band sits flat and comfortable against adjacent fingers, making it an enduring choice for daily wear.
