Oval Diamond Ring

An oval cut takes a round diamond's brilliance and stretches it — the elongated shape reads larger for its carat weight and lengthens the finger. It works in almost any setting: solitaire, halo, three-stone, pavé or east-west. IGI-certified lab diamonds in solid gold (white, yellow or rose), made to order, with a photo and video record of yours being made.

100% Satisfied

I was nervous about buying a ring online but it seemed like it would be a wild goose chase trying to find an elongated hexagon moissanite engagement ring (which is what my now fiance wanted) so I took a chance with Brilliant Carats and I'm glad I did. The ring is high quality and the price can't be beat. I will be shopping with them again for a wedding band.

Why Oval Is So Loved

Benefits of the Oval Cut:

The elongated shape flatters slender fingers and provides a more substantial look for less.
Oval diamond engagement rings create a unique, soft outline that differs from the traditional round brilliant.
The shape offers a remarkable sparkle thanks to its modified brilliant cut, showcasing stunning fire and light play.
A higher ratio (length to width) adds elegance and creates the illusion of greater size.

Whether you prefer a minimal solitaire or a detailed bezel or halo style, the oval cut is a brilliant choice for those seeking distinction and enduring beauty.

Frequently Asked Questions

Q:What is an oval cut diamond?

A: An elongated, rounded shape with the same brilliant faceting as a round diamond — so it sparkles like a round but stretches longer across the finger.

Q: What settings suit an oval?

A: Almost all of them — solitaire, halo, three-stone, pavé, twist and east-west all work beautifully, which is why oval is one of the most versatile shapes

Q: Does an oval look bigger than a round?

A: Yes — for the same carat weight, an oval's elongated shape covers more of the finger and generally reads larger than a round.

Q: Can I stack oval rings with other bands?

A: Yes. Many of our designs are created with stacking in mind and can be paired with our wedding bands pair for a complete look.

Q: Why choose a lab-grown oval?

A: Lab-grown diamonds are IGI-certified and let the same budget reach a larger, cleaner oval — exactly where an elongated shape shows its size.
