1.5 ct Princess Lab-Grown Diamond Cathedral Three-Stone Engagement Ring

The three-stone idea lifted onto cathedral arches, so the row of squares sits raised and framed above the band. A 1.5 carat princess center, D color and VVS1 clarity, leads two matched sides at the crown. The arches add height and guard the corners while giving the ring real architectural presence. It is the dressiest way to wear a princess trio. Gold or platinum, set and finished to your size to order. The setting carries about 0.64 ct of white diamonds.
