How much does a 0.75 carat cushion diamond cost?

It depends on the 4Cs and whether the stone is natural or lab-grown — a lab-grown cushion gives you the full 0.75 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 0.75 carat cushion diamond a good size for an engagement ring?

Yes. 0.75 Carat is a popular, well-proportioned center, and every cushion 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 0.75 carat cushion 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.

0.75 Carat Cushion Diamonds

Three-quarters of a carat hits the value sweet spot: it reads close to a full carat on the finger at a noticeably gentler price, which is why it is a quiet favorite for first engagement rings. A soft, pillow-shaped cut with rounded corners and a romantic, vintage glow. Cushion diamonds balance brilliance with a warm, antique character.
