Buying guide

What a cushion cut looks like

A cushion is a square or slightly rectangular stone with rounded corners and large facets. It shows broad flashes of light and a soft, pillow-like outline, which gives it a slightly vintage feel. The rounded corners have no sharp points, so the stone is less likely to chip at the edges. At 1 carat, a cushion center sits neatly on the finger and pairs well with a straight wedding band.

Choosing the band

A thin plain band makes the cushion center look larger, and a rounded plain band feels smooth and simple. A pave band lines the top of the band with small lab-grown diamonds. The hidden halo adds a ring of small stones beneath the center, seen from the side, while the top stays a classic 1 carat cushion cut solitaire engagement ring. The cathedral design lifts the center on arches over a graduated pave band.

Metal and price

Platinum is naturally white and costs more. Gold comes in 10K, 14K or 18K white, yellow or rose gold. Yellow and rose gold warm the look of the center, while white metals keep it bright. Most rings are priced between about $975 and $1,100 in the lowest-priced metal, with the lab-grown diamond center included.
