Diamond fluorescence

There is common misconception that a diamond exhibiting fluorescence under ultra violet light has some kind of colour defect or transparency issue.

This NOT true at all. The naturally occurring fluorescence phenomenon is a unique completely hidden feature, which is present to some level in approximately 30% of all diamonds.

The effect is seen in Diamonds which have Carbon bonds which include boron.

Boron causes the diamond to glow when held under a powerful ultra violet light also known as blacklight.

The amount of boron in the Carbon bond making up the diamond will determine the level of fluorescence.  Fluorescence is rated by the Laboratory as Very Strong, Strong, Medium, Faint, None. This relates to the strength of the fluorescent glow under ultra violet light.
