Lab-grown diamonds are top of mind these days, particularly among consumers who appreciate transparency and contemporary innovation. The question that gets asked the most is a simple, but important one: Do lab-grown diamonds change color over time? At Bliss Diamonds, we believe clarity is confidence, so here’s the guide to answer your question!
Understanding What Lab-Grown Diamonds Really Are
Contrary to some enduring myths, lab-grown diamonds are not imitations or simulants. They are genuine diamonds that have identical chemical, physical, and optical properties to mined ones. The only difference is that they are man-made in a lab instead of originating in the depths of the earth.
Because this structure is the same, lab-grown diamonds react to time, light, and wear just like natural diamonds do.
Do Lab-Grown Diamonds Change Color Over Time?
The Short Answer: No
Lab diamonds don’t discolor over time. They do not fade in colour for a lifetime. An artificial diamond, a lab-grown gem used in jewelry, or a mined diamond; once formed, has its atomic structure set. And in terms of structure, light passes through the stone, so color is also involved. And everyday sources of sunlight, household lighting, or wear don’t change it.
Why the Color Stays Stable
Color in diamonds is caused by impurities or structural defects produced while the diamond is forming. All these conditions are strictly controlled in lab-grown diamonds, and color has always been a predictable outcome. When the diamond has been cut and polished, there’s nothing under normal day-to-day circumstances that can affect what it is internally. In other words, a lab-grown diamond graded today will resemble one decades from now.

What Can Affect Appearance (But Not Color)
The diamond, of course, is not changing color, but some external factors could cause it to temporarily appear different:
-
An accumulation of dirt and oil can cause a diamond to become dull or darken somewhat
-
Metal settings can affect the perceived warmth or coolness
-
Brilliance can be increased or decreased depending on the light source
A gentle cleaning will bring the diamond right back to its original sparkle with absolutely no long-term effect on color.
Lab-Grown Diamonds vs. Natural Diamonds: Color Stability
In terms of color retention, lab-grown and mined diamonds are on equal footing. Both are graded with the same colour grading scale, and both keep that grade forever. This is of particular significance for pieces like Eternity Rings & Eternity Bands, where seamless matching color throughout every single stone is critical to visual integrity.
Clearing Up Common Misconceptions
Some people have confused lab-grown diamonds with cubic zirconia or moissanite, which can look different over time. Lab-grown diamonds are completely different materials and do not yellow, fade, or blemish with time. Awareness of this makes it easier to separate notions that are no longer valid.
Final Thoughts: Color You Can Count On
So, do lab-grown diamonds change color over time? The answer is a clear no. They are also just as durable and permanent as mined diamonds, so you can treasure them for a lifetime. When treated with love and respect, a lab-grown diamond will always be the same as it was on day one; sparkling, clear, and true to its natural grade.
