Diamond fluorescence is a fascinating, natural phenomenon where diamonds glow when exposed to UV light. This is where our extensive knowledge and supplier network can assess the diamond by hand and determine if the fluorescence is positive or negative, thus ensuring that you make a worthy purchase. The presence of fluoresce can significantly affect a diamonds price, especially if the reaction is negative. At Tok Jewellers, we recommend that if a diamond has a Medium, Strong or Very Strong fluorescence grade, it should be inspected before purchasing to ensure that the fluorescence is positive. Diamonds with no or faint fluorescence can be purchased without hesitation, provided all other quality factors are ideal.
