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