Buying guide

Why a round solitaire

The round brilliant is the classic engagement ring shape. Its facets are arranged to return as much light as possible, so it gives the most sparkle of any cut. A 2 carat round measures a little over 8 mm across, a size that stands out on most hands. A solitaire setting puts all the attention on that one stone.

Band and setting options

The thin plain band is the most classic choice: it keeps the look simple and makes the center seem larger. The rounded plain band has a smooth, comfortable profile. The pavé band adds small lab-grown diamonds along the shank. The hidden halo places lab-grown diamonds under the center, seen from the side, and the cathedral style raises the stone on arches above a graduated pavé band. The 2 carat figure is the center stone; any accents are extra.

Metal and price

White gold and platinum make the round look even whiter. Yellow and rose gold give a warmer, more vintage feel. Platinum is the densest and most expensive choice, and 18K gold has a richer color than 10K or 14K. Rings start from about $1,500 with the center included, and most cost between about $1,500 and $1,550.
