Perfect for modern romantics who love clean lines and undeniable sparkle, a round lab-grown diamond captures both tradition and forward-thinking style.

What is a Round Lab Diamond?
A round lab diamond (also known as a round brilliant cut) is a diamond crafted in a laboratory using advanced technology that replicates the natural growing process of diamonds. What sets it apart is its cut: 58 carefully arranged facets designed to reflect light from every angle, creating unmatched sparkle.
The history of the round cut dates back to the early 20th century, when mathematician Marcel Tolkowsky established the “ideal” proportions for maximum brilliance. Today, that formula still defines the round cut as the most dazzling diamond shape.
Why Choose a Round Lab Grown Diamond?
Round lab diamonds remain the world’s favorite shape for good reason. Here’s why they might be perfect for you:
-
Unmatched brilliance: The round cut maximizes light reflection, giving you the most sparkle of any diamond shape.
-
Timeless appeal: A classic that never goes out of style.
-
Versatility: Looks incredible in almost every setting, from solitaires to halos to modern minimalist bands.
-
Ethical elegance: With a lab-grown round diamond, you enjoy the same beauty as mined, without the environmental and social impact.
-
Value for money: More affordable than natural diamonds of similar size and quality.

Buying Guide – What to Look For
When shopping for a round lab diamond, keep the 4Cs in mind:
-
Cut – The most important factor. A well-cut round diamond sparkles the brightest.
-
Carat – Decide on size based on your budget and preference; round diamonds face up slightly smaller than elongated shapes, so you may want to go a touch bigger.
-
Color – Round cuts hide color well, so you can often choose a near-colorless grade without sacrificing beauty.
-
Clarity – The brilliance of the round cut masks inclusions, so you don’t need the absolute highest clarity for a beautiful stone.
Shape-specific tip: Round diamonds are the best at maximizing sparkle, making them the most forgiving choice for everyday wear.
Recommended settings: Solitaires, halos, pavé bands, and sleek modern bezels all showcase the round cut beautifully.
