1.5 carat elongated cushion diamonds: what to expect
A 1.5 carat diamond is a confident step up from one carat, large enough to read clearly as a statement stone. It looks about 14% wider than a 1 carat stone of the same shape and shows around 31% more surface from above, even though it weighs half as much again.
How big is a 1.5 carat elongated cushion diamond?
A 1.5 carat elongated cushion diamond typically measures about 7.6 x 5.9 mm, based on the stones in our stock today. A round diamond of the same weight measures about 7.3 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 1.5 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. Colour and inclusions start to show more at this size, so G or better and VS2 or better are worth considering, particularly in step cuts.
1.5 carat elongated cushion diamond prices
Prices step up again at 1.50 carats, so a stone between 1.50 and 1.60 gives the look of a "carat and a half" for the least premium.
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 1.5 carat elongated cushion diamond in our stock is £1,697 natural, against £299 lab grown. Compare 1.5 carat elongated cushion lab grown diamonds.
Other sizes
Compare elongated cushion natural diamonds at 1 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.
