Fancy Color Lab Grown Diamonds: Pink, Yellow and Blue

Quick answer: Fancy color lab grown diamonds are real diamonds in shades like pink, yellow, blue and green. They are graded by the strength of their color, from Fancy Light up to Fancy Vivid, and they cost a small fraction of what natural colored diamonds cost. Many get their color during growth, while others are color-treated after growth; a good grading report tells you which.

Natural colored diamonds are among the rarest gems on earth. Lab grown fancy colors make that look attainable. Here is what to know before you choose one.

How Lab Grown Diamonds Get Their Color

• Yellow: small amounts of nitrogen in the crystal create a warm yellow tone.
• Blue: tiny amounts of boron create blue shades.
• Pink and red: usually created by treating a grown diamond with controlled processes after growth.
• Green: commonly produced with post-growth treatment as well.

Treatments are stable and permanent, but they must be disclosed. An IGI report for a colored lab grown diamond states whether the color is "as grown" or treated.

Fancy Color Grades Explained

Colored diamonds are graded by hue (the color itself), tone (light or dark) and saturation (strength). Grades usually appear in this order, from weakest to strongest:

You will also see modifiers such as "brownish pink" or "greenish blue." The last word is the main color; the first describes a secondary tint.

Buying Tips for Fancy Color Lab Diamonds

• Color comes first. With colored diamonds, color matters more than clarity. VS clarity is plenty.
• Choose the shape carefully. Radiant, cushion and oval shapes concentrate color well. Round brilliants can make color look lighter.
• Check the report. Confirm the color grade and whether the color is as grown or treated.
• See real photos. Color can look different under different lighting, so ask for photos or video in daylight.

Frequently Asked Questions

Are pink lab grown diamonds real diamonds?

Yes. They are real diamonds; the pink color comes from their growth or a disclosed post-growth treatment.

Will a treated color fade?

No. The treatments used for lab grown diamonds are permanent under normal wear. Avoid extreme heat such as jewelry repair torches directly on the stone.

What is the rarest fancy color?

In nature, red, pink, blue and green diamonds are extremely rare. In lab grown diamonds, all of these colors are accessible.

Is Fancy Vivid better than Fancy Intense?

Vivid is more saturated. Whether it looks better is personal; some people prefer a softer Intense tone.

The Bottom Line

Fancy color lab grown diamonds let you wear a bold, rare-looking color at an approachable price. Choose the color you love, check the grade and treatment on the IGI report, and pick a shape that shows color well.
