What Is a Round Brilliant Cut Lab Grown Diamond?
The round brilliant cut lab grown diamond is a diamond created in a controlled laboratory environment and faceted into the iconic round brilliant shape. This cut features 57 or 58 precisely aligned facets, engineered to maximize light reflection, refraction, and dispersion.
Because of its symmetry and proportions, the round brilliant cut delivers more sparkle than any other shape, making it the benchmark against which all other diamond cuts are measured.
Key Characteristics
- Perfect circular outline
- Exceptional fire and brilliance
- Ideal for all jewelry styles
- Most forgiving cut for inclusions
The History of the Round Brilliant Cut
The evolution of the round brilliant cut is a journey of artistry and science. Early diamonds were cut simply to preserve weight. Over centuries, mathematicians and gemologists refined proportions to unlock maximum sparkle.
In the early 20th century, the modern round brilliant cut emerged, based on precise angles that optimize light return. Today, this same cut is applied flawlessly to lab grown diamonds, preserving tradition while embracing innovation.

Understanding Lab Grown Diamonds
Lab grown diamonds are real diamonds. They share the same chemical composition (carbon), crystal structure, hardness, and optical properties as mined diamonds.
How They Are Created
- HPHT (High Pressure High Temperature): Mimics natural diamond formation
- CVD (Chemical Vapor Deposition): Grows diamonds layer by layer
Both methods result in authentic diamonds indistinguishable from natural ones without advanced testing.
The Science Behind the Brilliance
The round brilliant cut is governed by physics. Each facet angle is calculated to reflect light internally and return it to the viewer’s eye.
| Optical Property | Effect |
|---|---|
| Brilliance | White light reflection |
| Fire | Colored light dispersion |
| Scintillation | Sparkle when moving |
The 4Cs Explained in Detail
Cut
Cut is the most critical factor for a round brilliant lab grown diamond. An excellent cut can make a lower color or clarity diamond appear stunning.
Color
Lab grown round diamonds are commonly available from D (colorless) to J (near colorless). The round shape hides color exceptionally well.
Clarity
Thanks to its brilliance, inclusions are less visible in round diamonds. VS and SI grades offer excellent value.
Carat
Carat weight affects size, but cut quality determines visual impact. Lab grown diamonds allow larger carat sizes at better value.
Cut Quality & Light Performance
An ideal round brilliant cut lab grown diamond follows strict proportion guidelines:
- Table: 54–58%
- Depth: 60–62.5%
- Crown Angle: ~34–35°
- Pavilion Angle: ~40.6–41°
Lab Grown vs Natural Diamonds
| Aspect | Lab Grown | Natural |
|---|---|---|
| Origin | Laboratory | Earth-mined |
| Price | More affordable | Higher cost |
| Ethics | Conflict-free | Varies |
| Appearance | Identical | Identical |
Pricing & Value Analysis
Round brilliant cut lab grown diamonds typically cost 30–60% less than equivalent natural diamonds. This allows buyers to prioritize cut quality, size, or setting without compromise.
Ethics & Sustainability
Choosing a lab grown round brilliant diamond supports sustainability. These diamonds require no mining, preserve ecosystems, and ensure transparent sourcing.
