What to Look for in Blue Diamonds

Blue with an accent color

Terms such as “Greenish Blue” or “Grayish Blue” indicate a secondary color. This makes the stone appear cooler or more muted—and often less expensive—than pure blue.

Compare the intensity

Fancy Light has an icy, bright appearance. Fancy Vivid displays a rich, vibrant blue. Watch the video to see if the color is evenly distributed throughout the stone.

The Right Metal

White gold and platinum accentuate the cool tone. Yellow gold provides a warm contrast, but can make light-colored stones appear slightly greenish.

Frequently Asked Questions

How do blue diamonds get their color?

In natural gemstones, boron within the crystal is usually what gives them their blue color. In lab-grown diamonds, boron can be incorporated during the growth process, but the color may also result from a post-treatment process. The report specifies this.

How much does a blue diamond cost?

Lab-grown stones are available starting at a few hundred euros. Natural blue diamonds are extremely rare and fetch millions at auction. You can see the current prices in the list above.

Is a blue lab-grown diamond a real diamond?

Yes. It is made of crystalline carbon and has the same hardness as a natural diamond. The report identifies it as lab-grown.

Which cut works best with blue diamonds?

Oval, cushion, and radiant cuts show off the color particularly well because their facets trap the light within the stone. With an emerald cut, the color appears calmer and clearer.

Lab-grown diamond or natural diamond?

Lab-grown diamonds and natural diamonds are both composed of pure carbon and share the same crystal structure, hardness, and refractive index. The difference lies in their formation: one forms over millions of years in the Earth’s mantle, the other in a matter of weeks in a laboratory. Visually, they are indistinguishable without specialized laboratory equipment. Lab-grown diamonds are significantly less expensive than comparable natural diamonds, which is why, with the same budget, you can often get more carats or a higher clarity grade. Both types come with a laboratory certificate from us; you can look up the report number directly with the laboratory.
