LAB-GROWN FANCY COLORED DIAMONDS
Lab-grown fancy colored diamonds have the exact same chemical composition, crystal structure and optical properties as their natural counterparts — the only difference is where they're formed. Instead of forming over billions of years deep within the earth, they're grown in a matter of weeks inside a controlled laboratory environment using either Chemical Vapour Deposition (CVD) or High Pressure High Temperature (HPHT) technology.
Just as with natural stones, color in a lab-grown diamond comes from trace elements or structural characteristics introduced during formation — nitrogen, boron and hydrogen all play the same role in a lab as they do underground. This means a lab-grown fancy colored diamond isn't an imitation; it's a genuine diamond with genuine color, verified and graded by the same gemological laboratories used for natural stones.
Because supply isn't limited by geological rarity, lab-grown fancy colored diamonds — including purple diamonds — are typically available in larger sizes and at a fraction of the price of their natural equivalents, without any compromise on beauty, durability or certification.
PURPLE LAB-GROWN DIAMONDS
Purple diamonds are exceptionally rare in nature, prized for their soft lavender to rich violet-purple hues.
In a lab-grown purple diamond, this same color is produced by a highly specialised HPHT treatment producing the rare color centre responsible for true purple — one of the most technically demanding colors to reproduce, even in a lab. The result is a stone that is optically, chemically and visually identical to a natural purple diamond of the same color grade.
GRADING OF LAB-GROWN FANCY COLORED DIAMONDS
Lab-grown fancy colored diamonds are graded using the exact same color, intensity and quality standards as natural fancy colored diamonds. Leading gemological laboratories — including IGI and GIA — assess hue, tone and saturation using the same nine-level intensity scale, and issue a full grading report that clearly states the diamond's laboratory-grown origin.
- Faint
- Very Light
- Light
- Fancy Light
- Fancy
- Fancy Intense
- Fancy Vivid
- Fancy Dark
- Fancy Deep
For purple diamonds, the deeper and more even the color saturation, the greater the value — the same principle that applies to natural stones, just at a significantly more accessible price point.

Frequently Asked Questions About Lab-Grown Fancy Purple Diamonds
What is a lab-grown purple diamond?
A lab-grown purple diamond is a real diamond, grown in a controlled laboratory environment rather than mined from the earth. Its purple color comes from a highly specialised HPHT treatment producing the rare color centre responsible for true purple — one of the most technically demanding colors to reproduce, even in a lab.
Is a lab-grown purple diamond a real diamond?
Yes. Lab-grown diamonds share the same chemical composition, crystal structure, hardness and optical properties as natural diamonds. The only difference is their origin, which is disclosed on every certificate.
How much more affordable are lab-grown purple diamonds than natural ones?
Because they aren't limited by geological rarity, lab-grown fancy colored diamonds are typically significantly more affordable than natural stones of the same color and intensity — often by 50% or more, especially in larger carat weights.
Are lab-grown purple diamonds certified?
Yes. Every lab-grown purple diamond we sell is independently certified by a leading gemological laboratory such as IGI or GIA, with the report clearly stating its laboratory-grown origin alongside its color, clarity, cut and carat weight.
Are lab-grown purple diamonds a good choice for engagement rings?
Absolutely. Lab-grown purple diamonds offer the same beauty and durability as natural stones, with the added benefit of a fully traceable, ethical origin and a larger choice of sizes within most budgets.
How can I tell a lab-grown diamond from a natural one?
Visually, they're identical — even trained gemmologists cannot distinguish them by eye. The only reliable way to identify a lab-grown diamond is through specialist laboratory equipment, and every stone we sell comes with a certificate stating its origin.
