0.5 Carat Princess Diamonds

0.5 Carat Princess diamonds — common questions

How much does a 0.5 carat princess diamond cost?

It depends on the 4Cs and whether the stone is natural or lab-grown — a lab-grown princess gives you the full 0.5 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 0.5 carat princess diamond a good size for an engagement ring?

Yes. 0.5 Carat is a popular, well-proportioned center, and every princess 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 0.5 carat princess 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.
