I have always heard that a real diamond (in a setting)has to have holes behind the stone so it may breathe and this is also a way you can tell if it is real…they say fake diamonds if you look at the band under the stone,if there are no holes for it to breathe it is fake…So you tell me true or false?…..thank you,Donna
When a jeweler talks about a diamond needing to breathe, he is referring to the light needed to sparkle. If the diamond is too covered up, it has no air and will not sparkle. Diamonds don’t always have holes and cz’s are not always covered up. Each diamond or cz maybe different.
