Do lab grown diamonds glow under uv light?

Lab-grown diamonds, much like natural diamonds, can exhibit fluorescence when exposed to UV light. This means they can glow or emit light under UV conditions. However, the glow is only visible when the diamond is exposed to UV rays and will not persist in the absence of a UV source.

It’s important to note that not all diamonds fluoresce, and the intensity of the fluorescence can vary. Only about 25% to 35% of diamonds show some degree of fluorescence when examined with a standard long-wave UV lamp.

If you’re considering purchasing a lab-grown diamond, it’s recommended to view it under both UV and normal lighting to understand how it may appear in different environments.
