What is a lab-grown colored diamond?
A lab-grown colored diamond is a real diamond, created in a lab, whose color comes from an element present in the crystal. Like every diamond, it is pure carbon, with a hardness of 10 on the Mohs scale and the same sparkle as a mined diamond. It is also called a synthetic colored diamond, lab-created fancy color diamond or lab-grown fancy diamond: these terms all describe the same stone.
A diamond's color has precise causes, identified by GIA (source):
- yellow comes from nitrogen, an element present in traces in the crystal;
- blue comes from boron;
- pink comes, in nature, from a distortion of the crystal structure. In the lab, it is most often produced by a treatment after growth, which creates the color within the diamond.
The lab reproduces what nature does, but in a controlled way: the color is even and chosen at creation. Every Laveran lab-grown diamond is IGI or GIA certified, with no fluorescence. To learn more about how they are made and other shades (green, black, red), read our guide colored lab-grown diamonds: everything you need to know.
How much does a lab-grown colored diamond cost?
At Laveran, a lab-grown colored diamond ring costs from €880 (0.30 carat) to €6,516 (5 carats), depending on the setting and the weight of the stone. The price is the same for a yellow, pink or blue diamond. Here are the real prices of our four ring families, as of October 2026:

Yellow, pink or blue diamond: what price for each color?
In the lab, all three colors cost the same; in nature, the gap between them is huge. Here is what to know about each shade.
Yellow diamond: price and character
The yellow diamond, sometimes called "canary" when its color is vivid, is the sunniest color. At Laveran, a yellow diamond ring costs from €880, and €1,744 for a 1 carat yellow diamond solitaire. It is also the least rare natural diamond color, which is why it is the one you see most often in jewelry stores. For its meaning and history: yellow diamond, meaning and price.
Pink diamond: price and rarity
The pink diamond is the most requested color for an engagement ring. In nature, it is extremely rare: according to GIA, only a tiny share of diamonds are pink, and the finest vivid pinks sell for more than $2 million per carat at auction (source). A lab-grown pink diamond costs the same as a white diamond: pink diamond rings from €880, €1,744 for 1 carat. Its history: the pink diamond.
Blue diamond: price and prestige
The blue diamond, colored by boron, is the color of prestige, worn by some of the most famous diamonds in history. Natural, it reaches prices out of reach. Lab-grown, a blue diamond ring costs from €880, and a 1 carat blue diamond in a halo €2,344. To learn more: blue diamond, mysteries and marvels.
Natural or lab-grown colored diamond: what is the difference?
Only the origin changes: a lab-grown colored diamond has the same material, hardness and sparkle as a natural one, at a completely different price.
| Criterion | Lab-grown colored diamond | Natural colored diamond |
|---|---|---|
| Material | Pure carbon | Pure carbon |
| Hardness (Mohs) | 10 | 10 |
| Cause of color | Nitrogen (yellow), boron (blue), post-growth treatment (pink) | Nitrogen (yellow), boron (blue), crystal distortion (pink) |
| Color consistency | Controlled, even | Varies widely from stone to stone |
| Certificate | IGI or GIA at Laveran | GIA or another lab |
| Price of a 1 carat ring | €1,744 at Laveran (solitaire) | Far higher; vivid pinks and blues reach record prices at auction |
At equal quality, a lab-grown diamond costs up to 80% less than a natural diamond, and the gap is far wider for rare colors. The IGI or GIA certificate clearly states the lab-grown origin: learn more in our article on IGI and GIA certification.
Which colored diamond engagement ring should you choose?
A solitaire gives the color all the attention; a halo of white diamonds frames it and makes it look more intense. Four families, all available in yellow, pink and blue:
- The solitaire, for bold, straightforward color: Palais Royal yellow diamond ring or Montaigne oval pink diamond, from €880.
- The pavé band, a colored diamond set on a line of white diamonds: Vendôme pear pink diamond ring, from €1,280.
- The halo, a circle of white diamonds around the colored stone that makes it look larger: Odéon oval blue diamond ring, from €1,480.
- The double halo, two rows of diamonds for a very bright ring, from €1,580.
Which shape for a colored diamond?
Oval, cushion and pear bring out color better than round. Their cut lets light travel through more of the stone, which deepens the perceived shade. Round remains the most brilliant; emerald cut and marquise are more graphic. At Laveran, yellow, pink and blue diamonds come in round, oval, cushion, pear, marquise and emerald cut, from 0.30 to 5 carats. The full selection is in the colored diamonds collection, and current trends in our article on colored diamond engagement rings.
Which metal for a yellow, pink or blue diamond?
The right metal either extends the color or makes it stand out by contrast. A few pairings that work:
| Diamond color | For a tone-on-tone look | For contrast |
|---|---|---|
| Yellow diamond | 18k yellow gold: warm, luminous | White gold or platinum: the yellow looks brighter |
| Pink diamond | 18k rose gold: soft, romantic | White gold or platinum: the pink stands out clearly |
| Blue diamond | White gold or platinum: cool, elegant | Yellow gold: a bold warm-and-cool contrast |
Whatever you choose, each ring is made to order in 2 to 3 weeks, with complimentary engraving, free insured hand delivery and returns within 30 days. It comes with a lifetime warranty, free lifetime resizing and free lifetime polishing and prong checks.
