Do Lab-Grown Diamonds Get Yellow Over Time?

Do Lab-Grown Diamonds Get Yellow Over Time?

Quick Answer:

No, lab-grown diamonds do not turn yellow(cloudy) over time. The color of a lab-grown diamond remains stable forever due to its chemical purity and lack of impurities. This is in contrast to some natural diamonds, which may develop a yellowish tint due to exposure to radiation or other environmental factors. However, it's worth noting that the color of a lab-grown diamond can vary depending on the conditions under which it was grow.


If you're considering a lab-grown diamond, you may have heard misinformation that it can become yellow or cloudy over time. This simply isn't true - a real lab diamond has the same stable properties as a mined diamond. With proper care, a quality lab diamond will retain its color and brilliance forever.

Why Don't Lab-Grown Diamonds Get Yellow Over Time?

Lab-grown diamonds are manufactured through advanced processes like CVD (chemical vapor deposition) and HPHT (high pressure, high temperature) that precisely replicate the conditions under which natural diamonds form. This gives them the same durability, hardness, and optical stability as mined diamonds.

A well-cut, high-quality lab diamond will not fade, cloud, or change color after years of wear. While cheap simulated diamonds like cubic zirconia can become cloudy, real lab diamonds do not change because their chemical structure is identical to natural stones. You can trust your lab diamond to stay dazzlingly white and brilliant over your lifetime.

Dispelling Common Misconceptions

Strong Fluorescence in Rare Cases

While rare, some lab diamonds exhibit very strong blue fluorescence under UV light that can lend a hazy or oily appearance. The stone's chemical composition causes this, not any instability in the diamond itself.

When buying a diamond with strong fluorescence, carefully inspect it in different lighting. A reputable retailer will disclose any potential visual impacts. For most lab diamonds, fluorescence is not an issue affecting their appearance.

Clarity Affects Apparent Cloudiness

One common misconception is that lower-clarity lab diamonds appear cloudy simply due to having more inclusions. In reality, diamonds with prominent clouds, twinning wisps, and large feather inclusions can face up slightly hazy or milky.

But this effect is due to the inclusions diffusing light, not the diamond losing stability. Even with significant inclusions, the lab diamond remains structurally sound. Carefully review clarity details like plotting diagrams when selecting SI clarity diamonds.

Low-Quality Lab Diamonds May Change

While rare, some exceptions exist where lower-quality lab diamonds with structural flaws may exhibit minor color changes under UV lighting. These diamonds usually have significant impurities and are treated to improve poor initial color.

Reputable lab diamond retailers like Brillistar reject these kinds of inferior stones, so you can shop confidently, knowing your diamond will not alter over time. When properly manufactured, a lab diamond is optically and chemically just as stable as a mined counterpart.

Caring for Your Lab Diamond

While a quality lab diamond holds its optical properties permanently, you should still clean your diamond jewelry regularly. An annual professional cleaning and occasional cleaning at home will keep oils and residue from building up on the surface, which can reduce shine.

Clean with gentle dish soap and water only, and avoid ultrasonic cleaning of softer ring settings that could get damaged. Also, store your diamond jewelry safely, as hard knocks and blows can chip even the hardest diamonds. With basic care, your lab diamond will sparkle forever.

Caring for Your Lab Diamond


While most reputable lab diamond jewelers like Brillistar offer exceptional stones, always verify a diamond's quality before purchase. Review lab certification, scope images, videos, and origin details carefully. The highest-graded diamonds from ethical providers will remain optically perfect and brilliant for future generations.

In conclusion, lab-grown diamonds offer impressive stability and shine for diamond lovers who value ethics and sustainability. Take the time to find a high-quality lab diamond from a trusted source, and your investment will stay brilliantly dazzling forever.
