Do lab-grown diamonds fade?

We often hear questions about whether the color of lab-grown diamonds will fade, will it change over time? Some consumers remain skeptical about the long-term stability of lab-grown stones. Let’s separate fact from fiction when it comes to color stability of lab-grown diamonds.

Understanding the Creation Process

Modern methods for growing diamonds in labs allow for precision control during the manufacturing process. The ability to carefully regulate factors like heat, pressure, and growth times enables producers to cultivate stones with consistently reliable qualities. Diamond growers incorporate stringent quality testing throughout production to verify color properties. The result is lab-grown diamonds engineered to exhibit stable color within their target grading range.

While trace impurities may be incorporated to assist growth, reputable diamond manufacturers carefully control their levels to avoid excessive defects that could impact color stability. Advanced technology has truly elevated lab diamond production to an art form that allows their optical qualities to rival those of mined diamonds.

Assessing Color Grading Standards

High-quality lab diamonds are graded on the same GIA or AGS color scale as mined diamonds, ranging from D (colorless) to Z (light yellow/brown). Those awarded the top D-F colorless grades by these labs have passed the rigorous spectrometer testing to confirm complete absence of color. The lab’s extensive protocols and instrumentation allow for extremely precise color assessment, far beyond what we can detect with the naked eye alone.

A diamond certified D-F colorless should remain within that colorless range permanently, with little discernible fading even after decades of wear. When a respected grading lab certifies the color grade, it provides assurance that the diamond exhibits no detectable elements that could lead to future color change.

Exceptions Are Possible, But Rare

There are always tolerances in any manufacturing process, and extremely rare outliers can occur. Some lower quality producers may grow diamonds with higher impurity levels or structural defects. In even rarer instances, subtle color change over many years may be noticeable in stones with medium to lower color grades. 

However, among the top fabricators that most jewelers source from, instances of excessive or rapid fading are exceptionally uncommon in our experience. Given the microscopic tolerances achieved by advanced lab-grown diamond manufacturers today, significant fading should not be a concern for most stones.
