“In general, the results revealed that strongly blue fluorescent diamonds were perceived to have a better color appearance when viewed table-up with no discernible trend table-down.

Even the experienced observers did not consistently agree on the effects of fluorescence from one stone to the next. “For the average observer, meant to represent the jewelry buying public, no systematic effects of fluorescence were detected. Participants in the study included: trained diamond graders, trade professionals (e.g., jewelers), and average observers (general jewelry buying public). The GIA study selected a group of similarly graded diamonds with varying degrees of fluorescence to be observed and commented on by study participants. Given the results of a 1997 GIA study on the effect of ultraviolet fluorescence on a diamond’s appearance, we tend to toss the first half of that theory out the window and give slightly less credence to the second half. The “theory” has been that: 1) fluorescence has a negative impact on colorless diamonds (making them appear cloudy) and 2) a positive impact on faint yellows (blue fluorescence supposedly counter-balancing the yellow color and making the diamond appear whiter). It is common to find that diamonds with colorless grades (D-E-F) or near colorless grades (G-H-I-J) are lower in price when they exhibit fluorescence and faint yellow grades (K-L-M) are higher in price when exhibiting fluorescence. In the diamond industry, the existence of fluorescence in a diamond (caused by the natural mineral properties of the diamond), has caused many debates and has, in many instances, influenced the pricing of diamonds. When we speak of Diamond Fluorescence, we are referring to the diamonds tendency to emit a soft colored glow when subjected to ultraviolet light (such as a “black light”).īefore going into the details of fluorescence, here’s our overall opinion: the simple existence or absence of fluorescence should not influence your decision to purchase a diamond.ĭiamond Fluorescence is a hotly debated topic in the diamond industry, but a 1997 study by the GIA suggests fluorescence makes very little difference to the appearance of the diamond. While most gemologists prefer diamonds without this effect, some people enjoy it. Under most lighting conditions, this fluorescence is not detectable to the eye. The Isadora Collection gives you the freedom to pair classic rings with earrings, bracelets, and necklaces that together create a unique statement that is simply gorgeous.Fluorescence is an effect that is seen in some gem-quality diamonds when they are exposed to long-wave ultraviolet light (such as the lighting frequently seen in dance clubs).
