Details
Cathedral arches lift the center high and lead the eye up to a 1.0 carat lab-grown marquise, D color and VVS1 clarity, set between two bright companions. Raising the stone lets light pour underneath it while the arches guard the delicate points, so you get drama and durability in the same ring. The long navette shape spans the finger for a look that feels regal rather than merely large. Gold or platinum, set and finished to your size to order.
Shown with a 1.0 ct lab-grown marquise-cut diamond (D color, VVS1 clarity, GCAL certified) center for $2,049 total. Price shown is the complete ring; metal choice can change it.
