Princess Cut Medium Fluorescence Lab Grown Diamonds

Medium fluorescence is generally not a concern in a princess cut lab diamond. The brilliant-style faceting of the princess cut produces such intense light dispersion that any subtle fluorescence effect is overwhelmed by the stone's sparkle. GIA research indicates that fluorescence-related haziness is rare at the medium level. A well-cut princess cut with medium fluorescence will display normal brilliance and fire.

Yes, medium blue fluorescence can benefit a princess cut lab grown diamond in warmer color grades (G through J). The blue glow counteracts yellow body color when the diamond is exposed to UV-containing light sources like sunlight, making the stone appear up to half a color grade whiter. Combined with the princess cut's light-scattering facets that already minimize color perception, medium fluorescence can provide a meaningful whitening boost.

The princess cut's brilliant-style faceting scatters light into many small flashes, which disperses any fluorescence effect across the entire stone rather than concentrating it. This means that even if medium fluorescence creates a subtle blue tint under UV light, it appears as a gentle, even softness rather than a localized haze. The princess cut's faceting pattern is one of the most forgiving shapes for fluorescence.

Princess cuts can appear up to 15% larger than rounds at the same carat weight, and Do Amore's selection lets you maximize that size advantage across every quality grade. Do Amore offers a 60-day return policy with no restocking fees.
