1 carat elongated 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 elongated cushion diamond?
A 1 carat elongated cushion diamond typically measures about 6.6 x 5.2 mm, based on the stones in our stock today. A round diamond of the same weight measures about 6.4 mm across, so the elongated 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 elongated cushion diamond
Every stone here has a length-to-width ratio of 1.15 or more and its own photo; 1.25 to 1.35 is the most popular range, and higher ratios give a longer, slimmer stone. At this size G or H color and VS2 or SI1 clarity usually look white and clean to the eye, leaving more of your budget for cut and size.
1 carat elongated 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 natural diamond is formed over billions of years and each one is rare; many buyers value that origin. A lab grown diamond of the same grades costs far less. Today the lowest priced 1 carat elongated cushion diamond in our stock is $1,164 natural, against $298 lab grown. Compare 1 carat elongated cushion lab grown diamonds.
Other sizes
Compare elongated cushion natural diamonds at 1.5 carat, 2 carat, 3 carat or 5 carat. Or browse every elongated cushion natural diamond, from under a carat upwards.
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.
