Man-Made Diamond Buying Guide
Man-made diamonds are real diamonds grown in weeks instead of billions of years. This guide explains how they compare to natural stones, why they cost less, and how to buy them with confidence.
What Man-Made Diamonds Are
Man-made diamonds, also called lab-grown or synthetic diamonds, are chemically, physically and optically identical to natural diamonds. They are grown in high-pressure high-temperature or chemical vapor deposition chambers, then cut and polished exactly like mined stones.
Man-Made vs Natural Diamonds
| Property | Man-Made | Natural |
|---|---|---|
| Composition | 100 percent carbon | 100 percent carbon |
| Hardness | 10 Mohs | 10 Mohs |
| Brightness | Identical | Identical |
| Price | 40-70 percent less | Premium |
| Origin | Grown in a lab | Mined from the earth |
How to Buy with Confidence
Ask for a lab report that states the stone is laboratory-grown, and confirm the 4Cs just as you would for a natural diamond. Most graded man-made diamonds come with an IGI or GIA report, so the specification is fully documented.
