How Color Is Made
Lab diamonds gain color during growth, by adding elements such as nitrogen for yellow or boron for blue, or by treatment after growth.
Treatment history should be disclosed, since it affects value and sometimes care. Ask whether color is as-grown or treated.
Colors Available
Pink, blue, yellow, and green lab diamonds are widely available, including colors that are extremely rare naturally, such as vivid blue and pink.
Because lab production controls color more reliably, lab colored diamonds show more even color than many natural stones.
Price and Value
Lab colored diamonds cost far less than natural fancy color diamonds of the same color and size, which makes bold color accessible.
Resale value is lower than for natural fancy colors, so buy lab colored diamonds to wear, not as an investment.
Choosing a Stone
Choose by face-up color in natural light, and check whether color is as-grown or treated, since treatment should be disclosed and priced accordingly.
Cut for colored diamonds prioritizes face-up color over white sparkle, so compare stones side by side rather than by cut grade alone.
Lab Colored Diamonds FAQ
Are lab colored diamonds real diamonds?
Yes. They share the composition and hardness of natural diamonds, with color from growth or treatment.
Is treated color permanent?
Usually yes for standard treatments, but ask about the specific treatment and its care limits before buying.
Why are lab colored diamonds cheaper?
Lab production is controlled and repeatable, while natural fancy colors are rare. Rarity, not material, drives the natural premium.
Do lab colored diamonds hold value?
Less than natural fancy colors. Buy them to wear and enjoy, not as an investment.
