Buying guide

What makes a solitaire

A solitaire puts one main stone at the center of the ring. With a half carat lab-grown diamond, that single stone does all the work, so the shape and the band shape the whole look. Some of these rings add small lab-grown diamonds in the band or under the center, yet the top view still reads as a single stone.

Band options

A plain band is the classic choice and pairs easily with a wedding band later. A rounded plain band has a softer edge that feels smooth on the finger. A pave band sets small stones along the top for extra light. The hidden halo hides a ring of small stones under the center, seen from the side, and the cathedral style lifts the center on arches above a graduated pave band.

Metal and price

Platinum is naturally white and costs the most. Gold is offered in 10K, 14K or 18K, in white, yellow or rose. These rings start under $800 in the lowest-priced metal, and most sit around $1,050, with the center included. Any accents add to the ring's overall stone weight, and the 0.5 carat figure refers to the center stone.
