Doubtful, but I also think it depends on how large the stone is.
2.5 ct
So many questions....
First one- how old is the observer?
Plenty of spots that I could see when I was 25 are now invisible now that I'm 165 years old....The truth is- there's NO way to reliably tell if a stone is eye clean based on those pics. No matter how old the observer.
Late 20's, so likely to be detected
