FAQs

No fluorescence means the diamond shows zero UV-reactive glow. At 3 carats, this ensures the larger face-up area displays clean, unaffected light without any risk of haziness. The bigger the diamond, the more any fluorescence effect would be visible, making no fluorescence the safest choice at this substantial size.
More so than at smaller sizes. The larger face-up area at 3 carats means any fluorescence-related haziness is spread across more visible surface. No fluorescence eliminates all risk and ensures the diamond's substantial presence is defined by its cut quality and color, not by UV-related effects.
Yes. Fluorescence effects, when present, become more noticeable in larger diamonds because there's more surface area displaying any haziness. At 3 carats, which is about a carat above the average engagement diamond, fluorescence sensitivity increases meaningfully. No fluorescence provides the cleanest performance at this size.
When looking for 3 carat natural diamonds, look between 2.9 to 3.3 carats so that you give yourself the best selection which will help find the best value. Searching within this range across different no fluorescence options gives you the widest selection to compare cut quality, proportions, and overall value. A well-chosen 3 carat no natural diamond at the lower end of this range can look identical to one at the exact 3 carat mark while costing less.
