Consider the diamond’s certification
When buying a diamond, it’s important to ensure that it comes with a certification from a reputable gemological laboratory such as the Gemological Institute of America (GIA) or the American Gem Society (AGS). This certification ensures that the diamond has been graded based on the 4 C’s and is a genuine, natural diamond.
Consider the diamond’s fluorescence
Fluorescence is the diamond’s reaction to ultraviolet light. Some diamonds may appear milky or hazy in direct sunlight due to their fluorescence. While fluorescence can sometimes have a negative impact on a diamond’s appearance, it’s not always a bad thing. In fact, some people prefer diamonds with a faint to medium fluorescence as it can make the diamond appear whiter.
