1.5 carat radiant 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 radiant diamond?
A 1.5 carat radiant diamond typically measures about 8.1 x 5.7 mm, based on the stones in our stock today. A round diamond of the same weight measures about 7.4 mm across, so the radiant 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 radiant diamond
Radiants come square (ratio up to 1.08) or elongated (1.15 and up); the brilliant faceting hides small inclusions well. 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 radiant 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 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 1.5 carat radiant diamond in our stock is $568 lab grown, against $4,188 natural. Compare 1.5 carat radiant natural diamonds.
Other sizes
Compare radiant lab grown diamonds at 1 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.

A 1.5 carat radiant diamond typically measures about 8.1 x 5.7 mm, based on the stones in our stock today. Exact measurements are on each stone's certificate.
How much does a 1.5 carat radiant lab grown diamond cost?

Should I choose a natural or lab grown 1.5 carat radiant diamond?
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 1.5 carat radiant diamond in our stock is $568 lab grown, against $4,188 natural. Both are graded on the same 4Cs and come with a certificate.
