Drew

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 Choose an Oval Lab Grown Diamond?

The oval shape offers an elongated silhouette that creates a larger visual impact and a flattering finger profile, making it one of the most popular alternatives to round cut diamonds. Paired with the brilliance and affordability of lab grown diamonds, these oval cut rings represent the best of both worlds—elegance and value.

Each 1.5 carat lab grown diamond is physically identical to a mined diamond, but grown in a controlled environment free from harsh chemicals. The only difference is origin—not beauty, durability, or symbolism.

Certified Quality and Uncompromised Style

Every lab grown stone is IGI or GIA certified, evaluated for cut, clarity, color, and actual carat weight. These diamonds are hand-selected to meet the highest standards in diamond’s quality, giving you the confidence that your ring will shine for life.

The collection includes various designs—from solitaire to halo settings—all customizable in metals like white gold, yellow gold, rose gold, and platinum. Whether your style is minimal, vintage, or bold, our rings are made to match your personality, taste, and budget.

Made to Match Your Love Story

Your engagement ring should be as unique as your relationship. With our curated designs, you can choose the exact carat oval diamond, add your preferred metal and band style, and continue creating a ring that’s distinctly yours.

Each piece in this category is not only a sparkling centerpiece but also a reflection of your values—crafted without compromise and designed for a lifetime of love.
