Knife-Edge Pavé Arc Cathedral Engagement Ring Setting

The band rises to a sharp, clean ridge along the top, known as a knife edge, and lifts the center stone in cathedral arches. From the top it looks like a simple solitaire. The sparkle shows from the side: small lab grown diamonds run up the prongs and form an arc under the center stone. There are 39 accent diamonds, 0.20 ct in total, F color and VS2 clarity. The band is 2–2.2mm wide. It takes seven shapes: round, cushion, oval, princess, emerald, radiant or marquise.
