The Ultimate Guide to Lab-Grown Diamonds: Everything You Need to Know
Modern luxury is evolving—beauty and ethics now go hand in hand. Lab-grown diamonds offer the same brilliance, durability, and romance as mined stones, with a lighter environmental footprint.
At LUMEO, every piece begins with a conscious choice. This guide explains how lab-grown diamonds are made, how they differ from mined ones, and why they’re reshaping fine jewelry.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds. They share the same crystal structure, chemical composition, and hardness (10 on the Mohs scale) as mined stones. The difference is origin—created in controlled labs instead of extracted from the earth.
How Lab-Grown Diamonds Are Made
HPHT (High-Pressure High-Temperature)
Replicates natural conditions deep within the earth. Carbon is compressed under extreme pressure and heat until it crystallizes into diamond.
CVD (Chemical Vapor Deposition)
A carbon-rich gas is introduced into a vacuum chamber, forming diamond layer by layer. This newer process allows precise control of clarity and color.
Lab-Grown vs. Mined Diamonds
| Feature | Lab-Grown | Mined |
|---|---|---|
| Origin | Ethical, conflict-free labs | Mined from earth |
| Environmental Impact | Lower land & water use | Higher land & water use |
| Price | Typically 30–50% less | Premium cost |
| Certifications | IGI / GIA graded | IGI / GIA graded |
| Visual Difference | None to the eye | None to the eye |
Are Lab-Grown Diamonds Real?
Yes. They’re physically and optically identical to mined diamonds—specialized equipment is required to detect growth patterns. The FTC recognizes them as diamonds.
