A princess cut is a square brilliant with sharp, pointed corners. It has lively sparkle, close to that of a round, in a modern geometric outline. Its corners are the most exposed part of the stone, so prongs or a frame at each corner help protect them. At 2.5 carats, a princess cut lab-grown diamond makes a bold, crisp center.
Solitaires keep the square shape clean, with a plain band, a rounded plain band or pave lab-grown diamonds on the shank. The halo style circles the center with small stones and adds a three-row pave band. The hidden halo shows its accents only from the side. The cathedral style lifts the center on arches over a graduated pave band, and the three stone and side-accent styles add marquise, pear or round lab-grown diamonds beside it. Accents add weight beyond the center.
Every design is offered in 10K, 14K or 18K white, yellow or rose gold, and in platinum. White gold and platinum suit a bright, cool look; yellow and rose gold give a warmer contrast with the square white center.

Here a 2.5 carat princess cut lab-grown diamond ring starts at about $1,640, and most are priced between about $1,900 and $2,050. Those prices include the finished ring with its center set, in the lowest-priced metal option. Higher gold karats, platinum and styles with more lab-grown diamond accents cost more. Lab-grown diamonds cost far less than natural diamonds of the same size.
