Diamonds light in the uv!

Fluorescence, or the glow of a diamond in ultraviolet light, is normal for this gemstone. But not all diamonds are. Hence, there are many points about the fact that a real diamond is only fluorescent, and vice versa, as if fluorescence is a flaw in a diamond.

Both theories are wrong. Fluorescence is just a property that some diamonds have. By the way, if a certificate is attached to a stone – usually a diamond ring is sold with a certificate from 0.25 carats – then this characteristic is spelled out in it. For example, the GIA certificate indicates the degree of luminescence as Strong/Very Strong or Faint, Slight, Medium (minor). If there is no glow, in the certificate it is also indicated as None.

In this case, jewelry stores often overestimate the price of diamonds without fluorescence – they are caught less often, and their properties of luster and glow are allegedly better. However, GIA (Gemological Institute of America) claims that the difference between diamonds is so minimal that discounts on diamonds with fluorescence are absolutely not justified.
