Buying guide

What a princess cut looks like

A princess cut is square from above, with many brilliant facets that throw a lot of sparkle. It has a crisp, modern look. Its four pointed corners need protection, so a solitaire setting holds each corner with a prong. A 1 carat princess cut lab-grown diamond looks a little smaller from above than a round of the same weight, because more of its weight sits in its depth.

Band choices

  • Plain: a thin or rounded metal band for a clean, classic solitaire.
  • Pavé: small lab-grown diamonds along the band.
  • Hidden halo: a row of small lab-grown diamonds below the center, seen from the side.
  • Cathedral with graduated pavé: arches lift the center and the accents grow toward it.

The 1 carat figure is the center alone; accents are extra, on top of the center's weight.

Gold or platinum

White gold and platinum both suit a colorless princess cut. Yellow and rose gold give a warmer look. 10K gold is the toughest and most affordable, 14K is the common middle ground, and 18K has the most gold. Prices start from about $950 for the finished ring in the most affordable metal option, and many are around $1,000 to $1,100.
