Unless there are diamonds with strong fluorescence in the summer sunshine with strong ultraviolet rays, we can see the existence of fluorescence with the naked eye. Fluorescent diamonds have no effect on diamonds. Based on the optical angle of diamonds, the fire color of diamonds with weak fluorescence is higher than that without fluorescence, and diamonds with weak fluorescence are more shiny. Therefore, the price of two diamonds with the same weak fluorescence effect of 4C carats will be higher! The fluorescence of bare diamonds is divided into five grades according to GIA standard. None/none, weak/weak, medium/medium, strong/strong, very strong/strong.
In fact, the choice of diamond fluorescence is a more personalized problem, which is chosen according to personal preference, but there is still one thing to pay attention to. If the fluorescence is too strong, the price will be greatly reduced, because too strong fluorescence will greatly affect the fire color, so be wary of buying diamonds with strong fluorescence at high prices!
Fluorescent diamonds, like eight hearts and eight arrows, are all propaganda means, and these effects may not be observed at all in normal life.
