What does “florescence” mean on a diamond certificate?
Florescence is a natural property of some diamonds. If you hold a florescent diamond under a black light, it will glow purple! It will also glow in a discotheque. This property makes a yellower diamond look whiter, so that can be good. It can also make a whtie diamond look milky. If the cert says it has strong florescence, the price will be cheaper, so if you don’t go to discos, the diamond will be a great deal!
