What can affect a diamond's sparkle beyond its cut quality?

The sparkle of a diamond, often referred to as its brilliance, is significantly influenced by the interplay of factors beyond just its cut quality. In this case, both the quality of the rough diamond material and the presence of fluorescence contribute to the overall sparkle.

The quality of the rough diamond material is critical because diamonds that originate from higher-quality rough tend to have fewer inclusions and better clarity. This enhances the ability of light to pass through the stone and reflect off its facets, increasing its brilliance. If a diamond is cut from lower-quality rough, it may have more visible imperfections that can detract from its overall appearance.

Fluorescence, which is the phenomenon where diamonds emit a soft glow when exposed to ultraviolet light, can also play a role in a diamond’s visual appeal. In some cases, fluorescence can enhance the diamond's sparkle, making it appear more lively under certain lighting conditions. However, it can also lead to a milky or hazy appearance in some diamonds, which can impact their brilliance negatively, depending on the intensity and nature of the fluorescence.

By recognizing that both the quality of the material and the presence of fluorescence can affect a diamond’s sparkle, it becomes clear that these factors are integral to understanding and evaluating the beauty and light
