Round Cut No Fluorescence Diamonds

No fluorescence means no UV-reactive properties, ensuring completely neutral behavior in all lighting. The round brilliant's optimized faceting produces the most intense sparkle of any shape without any fluorescence interaction. In the natural market, non-fluorescent rounds may carry a slight premium (5% to 10%) at higher color grades.

No fluorescence is the safest default for colorless rounds (D through G). For near-colorless grades (H through J), faint to medium fluorescence can improve perceived whiteness and comes at a lower price in the natural market. So no fluorescence is optimal for higher colors but not necessarily the best value for every round buyer.

No. Sparkle is determined entirely by cut quality. A round with Excellent cut and no fluorescence sparkles identically to one with medium fluorescence and the same cut. Fluorescence only affects UV-light reaction, not light performance under normal conditions.
