1.5 carat oval 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 oval diamond?
A 1.5 carat oval diamond typically measures about 9.0 x 6.3 mm, based on the stones in our stock today. A round diamond of the same weight measures about 7.3 mm across, so the oval 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 1.5 carat oval diamond
A length-to-width ratio of 1.30 to 1.50 gives the classic oval outline; check the photo for a soft bow-tie rather than a dark one. 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 oval 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 oval diamond in our stock is $3,292 natural, against $603 lab grown. Compare 1.5 carat oval lab grown diamonds.
Other sizes
Compare oval natural 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.
