Diamond fluorescence can influence the appearance and cost of a diamond, varying from beneficial to potentially detrimental:Beneficial: For diamonds that possess slight yellow tones (graded I color or below), medium-strong fluorescence can counteract yellowish hues, making them appear whiter and more desirable in certain lighting conditions.Detrimental: In diamonds of very high color grades (D-F), medium-strong fluorescence may result in a milky or hazy appearance, especially under UV light, which can detract from the stone’s clarity and overall sparkle.Budget-Wise: Nearly-colorless diamonds with faint to medium fluorescence typically do not show any noticeable effect on the beauty of the diamond to the naked eye but are often priced lower than those without fluorescence. This can be a cost-effective choice for budget-conscious shoppers, allowing you to purchase a larger stone or allocate funds towards other diamond attributes like cut or clarity without compromising the visual appeal.
