1 carat cushion diamonds: what to expect
One carat is the most popular engagement ring size and the point where a diamond starts to look substantial on the hand.
How big is a 1 carat cushion diamond?
A 1 carat cushion diamond typically measures about 6.7 x 5.4 mm, based on the stones in our stock today. A round diamond of the same weight measures about 6.5 mm across, so the cushion looks a similar size on the hand. Carat measures weight, not size, so cut and proportions affect how big a stone looks.
Choosing a 1 carat cushion diamond
Decide between a square cushion (ratio up to 1.08) and an elongated cushion (1.15 and up) before comparing grades. At this size G or H colour and VS2 or SI1 clarity usually look white and clean to the eye, leaving more of your budget for cut and size.
1 carat cushion diamond prices
Prices step up at the 1.00 carat mark, so a stone just over it carries the "one carat" name for the smallest premium; anything from about 1.20 carats adds visible size.
Natural or lab grown?
A lab grown diamond has the same chemistry, hardness and sparkle as a natural diamond, at a fraction of the price, which is why it is a popular way to reach a larger size. Today the lowest priced 1 carat cushion diamond in our stock is $434 lab grown, against $1,466 natural. Compare 1 carat cushion natural diamonds.
Other sizes
Compare cushion lab grown diamonds at 1.5 carat, 2 carat, 3 carat or 5 carat.
Setting your diamond
Every diamond here can be set in an engagement ring, pendant or earrings made to order in our Bourton-on-the-Water workshop, hallmarked in the UK. Browse engagement rings or design your own. If the stone you want is not listed, our team can source it for you.
