5 Carat Old Mine Marquise Very Strong Fluorescence Diamonds

Very strong fluorescence creates an intense blue glow under UV light and has a higher likelihood of causing a hazy or oily appearance in normal lighting. For a 5 carat old mine marquise, always inspect the stone carefully since the broad facets can make any haziness more apparent.

Very strong fluorescence offers the deepest discounts of any fluorescence level, making a 5 carat old mine marquise more accessible. If the individual stone remains transparent with no milky effect, it can be an exceptional value, especially in warmer color grades where the blue glow offsets yellow tones.
