The Different Types of Lab Grown Diamonds
By growth method, by color, by treatment — a clear breakdown of the lab grown diamonds you'll come across.
“Lab grown diamond” is one term, but it covers a few different types. Knowing the categories helps you understand exactly what you're buying.
1. By growth method: CVD vs HPHT
|
CVD
Grown from carbon-rich gas at lower pressure. Known for high-clarity, colorless results. |
HPHT
Grown by recreating the heat and pressure deep underground. The original method. |

2. By color
Most lab diamonds are colorless or near-colorless, but they also come in fancy colors — yellows, pinks, and blues created by introducing trace elements during growth. Fancy colors are a striking, often more affordable way to stand out.
3. By post-growth treatment
Some stones are grown “as-grown” and left untreated; others are treated (for example with heat) to enhance color. A grading report will note any treatments, which is one more reason certification matters.
In short: a lab diamond can be described by how it was grown, its color, and whether it was treated — all of which appear on a good grading report.
And moissanite varieties
Moissanite has its own range too: classic colorless, near-colorless, and even fancy-colored options — plus a wide choice of cuts. Explore the shapes in How to Choose a Moissanite Cut.
