What Are Lab-Grown Diamonds?
A clear, simple guide explaining how lab-grown diamonds are made — and why they are real diamonds.
Lab-grown diamonds—also called lab-created diamonds—are real diamonds with the same physical, chemical, and optical properties as mined diamonds. The only difference is their origin: instead of forming underground over billions of years, they are grown in advanced laboratories using controlled conditions.
Every loose diamond sold at LabCreated.Diamonds is IGI or GIA certified and ships within 3–6 business days with a Lifetime Authenticity Guarantee.
How Lab-Grown Diamonds Are Made
Lab-grown diamonds are created using two cutting-edge technologies:
- HPHT (High Pressure High Temperature) — recreates the extreme heat and pressure found deep in the earth.
- CVD (Chemical Vapor Deposition) — grows diamond crystal layer by layer using carbon-rich vapor.
Both methods produce genuine diamonds with the same crystal structure as mined diamonds. These are not simulants or imitation stones.
Are Lab-Grown Diamonds Real Diamonds?
Yes. Lab-grown diamonds are chemically and visually identical to mined diamonds. They share the same:
- Hardness (10 on Mohs scale)
- Brilliance and fire
- Refractive index
- Durability
- Chemical composition (pure carbon)
They test as real diamonds on professional diamond testers and carry official certification from leading labs such as IGI and GIA.
Lab-Grown Diamonds vs. Simulants
Lab-grown diamonds should not be confused with diamond simulants like cubic zirconia or moissanite. Simulants may resemble diamonds in appearance, but they do not share the same physical or chemical properties.
- Lab-grown diamonds = real diamonds with identical structure and brilliance.
- Simulants = look-alikes made from different materials.
Why Choose a Lab-Grown Diamond?
- Exceptional value — typically 60–85% less than mined diamonds.
- Genuine diamond brilliance — identical sparkle and beauty.
- Certified quality — graded by IGI or GIA.
- Ethical & sustainable — no mining required.
- Greater transparency — clear videos, grading, and specifications.
Lab-grown diamonds offer the same beauty and durability as mined diamonds—at a much more accessible price.
