This thin platinum knife edge ring is a lovely combination of stylistic beauty and design. It features a 2mm wide band that would make an exemplary complement to a knife edge engagement ring. We selected platinum for these plain wedding rings for ladies because of the premium qualities of this precious metal. Platinum is resistant to tarnishing and is hypoallergenic, making it the choice of those that have sensitive skin.
