5 Carat Old Mine Marquise Medium Fluorescence Diamonds

Medium fluorescence produces a noticeable blue glow under UV light but rarely affects appearance in normal indoor or outdoor lighting. In a 5 carat old mine marquise, the effect is subtle enough that most wearers never notice it during daily use.

Medium blue fluorescence can actually help diamonds in the H through J color range appear whiter in daylight, since the blue glow counteracts faint yellow tones. For a 5 carat old mine marquise with warmer body color, this can be a smart value play.
