Buying guide

The princess cut at 3 carats

A princess cut is a square brilliant with sharp, pointed corners. It keeps a lot of its weight in its depth, so a 3 carat princess faces up a little smaller than a round of the same weight but has plenty of sparkle. Its four corners are the most exposed part of the stone, so they are held by prongs that cover each point.

Why white gold suits it

White gold gives the crisp, modern look a princess cut is known for, and it keeps the color of a colorless lab-grown diamond looking clean. It is plated with rhodium for a bright white finish, which wears over time and can be renewed. 10K is the hardest, 14K is the usual choice, and 18K has the most gold.

Styles to compare

A solitaire shows off the clean square outline. A halo squares off the look even more and makes the center appear larger. The hidden halo adds sparkle under the center without changing the top view. The three stone ring and the side-accent rings with pear or marquise stones widen the ring across the finger, and the cathedral lifts the center over a graduated pavé band.
