just had a conversation with a former ny diamond dealer i met at the gym. he says that the lab grown diamond industry is so wild right now that there are a flood of supposedly "mined" diamonds that are so good they are probably black market lab grown.

everyone is doubting all diamond these days due to black market labs creating amazing stones and destroying diamonds as "forever store of value"

traditionally lab groom diamonds needed to have a LG inscription buried in the stone, but so many of the diamonds now flooding the market are missing this subscription and seem too good to be true

he thinks that there are some Chinese labs that have created lab grown diamonds with boron so they fluoresce blue unlike lab grown, which fluoresce red or green. Apparently many diamond dealers have vaults of these questionable diamonds that are passing spectrometer testing originating from chinese dealers
