1 carat marquise 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 marquise diamond?
A 1 carat marquise diamond typically measures about 10.0 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 marquise shows more surface from above and looks larger. Carat measures weight, not size, so cut and proportions affect how big a stone looks.
Choosing a 1 carat marquise diamond
A ratio of 1.75 to 2.25 gives the classic marquise; both points should line up, and each is protected by a V-shaped claw. 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 marquise 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 marquise diamond in our stock is $1,776 natural, against $483 lab grown. Compare 1 carat marquise lab grown diamonds.
Other sizes
Compare marquise natural diamonds at 1.5 carat, 2 carat, 3 carat or 5 carat.

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.
