Why the Round Cut Remains Unrivalled
When only the most timeless and iconic will do, the round cut diamond reigns supreme. Coveted for its peerless brilliance and elegant symmetry, the round brilliant is the definitive choice for those with an eye for enduring style. And now, it’s possible to own this classic with a conscience—without compromising on quality, craftsmanship, or allure.
What Is a Round Cut Lab-Grown Diamond?
A round cut diamond—often referred to as a round brilliant—is precision-engineered for maximum sparkle, featuring 58 perfectly arranged facets that catch and reflect light from every angle. As the most popular shape globally, it’s a versatile choice for any style, whether minimalist or ornate.
At Skydiamond, our lab-grown round cut Skydiamonds offer the same beauty, fire, and clarity as mined stones—but with none of the ethical or environmental compromise.
