What Are Colored Lab-Grown Diamonds?

Colored lab-grown diamonds are real diamonds, identical in composition to colorless stones the only difference is the presence of trace elements or controlled conditions during growth that influence their hue.

They exhibit the same brilliance, hardness, and durability as traditional diamonds, but open a world of creative possibilities.

How Are Colors Created?

Color in diamonds forms when specific atoms or environmental conditions affect how light interacts with the crystal.
In labs, this process is replicated with precision, allowing for a range of natural hues from soft champagne tones to vivid fancy pinks.

Here’s how the main colors are achieved:

COLOR	HOW IT'S CREATED
PINK & RED	Adjusting crystal growth pressure or using post-growth treatments that alter lattice structure
BLUE	Adding trace elements of boron during growth
YELLOW	Introducing nitrogen atoms into the carbon structure
GREEN	Natural or lab-simulated exposure to low radiation
BLACK	Dense inclusions or controlled impurities
CHAMPAGNE & COGNAC	Slight variations in nitrogen concentration

Each stone's color is stable, permanent, and certified.

How Colored Diamonds Are Graded

Colored diamonds are graded differently than colorless ones.
Instead of D–Z, they’re classified by Hue, Tone, and Saturation:

Hue: The basic color (pink, blue, yellow, etc.)
Tone: How light or dark the color appears
Saturation: The intensity or vividness of the color

Example: Fancy Vivid Blue represents the deepest, most striking intensity level.
