Celestia Knife Edge Milgrain Engagement RingThis two toned engagement ring displays the perfect mix of tradition and modernity. It features a knife edge cathedral shank with a ridged spine detail. The arching shoulders are further embellished with five round diamonds, four of which are set in pairs and mounted on evenly spaced points or "stations." The diamond studded prong basket that secures the round central diamond forms the sparkling bridge and the inner shank.
