1.5 Carat Oval Diamonds

At a carat and a half the stone gains genuine board presence on the hand while staying well below the steep price jump at the two-carat threshold — a smart upgrade for buyers who want size without crossing a round-number premium. An elongated brilliant cut that looks larger per carat and flatters the finger. Oval diamonds pair the fire of a round with a distinctive, modern silhouette.

48,531 certified 1.5 carat oval diamonds in stock — natural and lab-grown.

1.5 Carat Oval diamonds — common questions

How much does a 1.5 carat oval diamond cost?: It depends on the 4Cs and whether the stone is natural or lab-grown — a lab-grown oval gives you the full 1.5 carat look for a fraction of a natural's price. Our diamond price calculator returns a live average from current inventory, or you can compare the in-stock stones below.
Is a 1.5 carat oval diamond a good size for an engagement ring?: Yes. 1.5 Carat is a popular, well-proportioned center, and every oval diamond we carry is independently certified (GIA or IGI). Pick your stone and set it into a matching ring through build-your-own.
Do you carry both natural and lab-grown 1.5 carat oval diamonds?: We carry both at this weight. Lab-grown gives you more size for the budget while natural carries traditional rarity — use the Natural and Lab filters to compare side by side. Both come fully certified.
