Do lab grown diamonds glow in the dark?

Lab-grown diamonds, much like their natural counterparts, can exhibit fluorescence when exposed to UV light, meaning they can glow under certain conditions. However, they do not inherently glow in the dark without a UV light source.

The glow is influenced by the diamond’s structure and impurities, and not all lab-grown diamonds will display this trait. It’s also worth noting that fluorescence does not significantly impact the value of a diamond; it’s more of a personal preference whether you’d like your diamond to have this characteristic.

If you’re interested in whether a specific lab-grown diamond exhibits fluorescence or phosphorescence, a professional gemologist can help determine that.
