None glow though with all other light sources off they do exhibit a faint bluish colour nothing as bright as a normal black light glow from something white under ir. Sunlight or black light. Be aware that while the majority of diamonds on the market will have a blue glow under uv light high quality diamonds will not.

Fluorescence refers to a diamond s tendency to emit a soft colored glow when subjected to ultraviolet light such as a black light. It is estimated that around 50 of all diamonds have fluorescence that can be seen in special conditions e g. Roughly 30 of diamonds fluoresce to some degree. If the diamond reflects a blue fluorescence it is most likely authentic.

Under a long wave uv lamp while around 10 fluoresce strongly enough to make a noticeable difference to the colour of the diamond when viewed in sunlight or incandescent low uv light. Fluorescence is the tendency of a diamond to emit a soft glow when exposed to ultraviolet light uv light. Hold the diamond in question under a long wave uv light also called a black light.
