Medium Fluorescence Diamonds

Medium fluorescence means the diamond emits a moderate blue glow when exposed to ultraviolet light. Under normal lighting, medium fluorescence rarely has a noticeable impact on appearance. In some cases, it may create a very subtle soft effect in strong UV environments like direct sunlight. Medium fluorescence is common in natural diamonds and generally not a concern for the appearance of a well-cut stone.

In the vast majority of cases, medium fluorescence does not make a diamond look hazy. The association between fluorescence and haziness is often overstated. GIA research has shown that fluorescence-related haziness is rare and primarily occurs at Strong and Very Strong levels, not at Medium. A well-cut natural diamond with medium fluorescence will typically display the same brilliance and clarity as a non-fluorescent stone.

Yes, medium blue fluorescence can noticeably improve the face-up whiteness of warmer color grades (G through J) in natural diamonds. When the stone is exposed to UV-containing light like daylight, the blue fluorescence counteracts the yellow body color, making the diamond appear up to one color grade whiter. This makes medium fluorescence a potential asset rather than a drawback in near-colorless diamonds.

Do Amore carries medium fluorescence diamonds that can actually benefit warmer color grades like I and J by counteracting faint yellow tones. Each purchase provides clean water access to one person in need.
