No Fluorescence Natural Diamonds

Diamonds with no fluorescence emit no glow under ultraviolet light. They are considered the purest option by traditional diamond buyers and carry a slight premium over fluorescent equivalents.

No-fluorescence diamonds are the safest choice for D–F colourless grades, where fluorescence could theoretically cause a faint hazy or milky appearance in rare cases. For buyers who want the cleanest possible light performance with zero variables, "None" fluorescence is the gold standard.

At MOH London, you can filter our entire natural diamond inventory by fluorescence grade. Every diamond below has been independently certified with "None" fluorescence by GIA or IGI.
