How can I distinguish laboratory-created and natural diamonds?

Hi,
How can I find if the diamond is ethically sourced or created in lab

I think they have to be marked as man-made on the stone itself.

Please make sure you are not buying a lab-created diamond you are wasting your money unfortunately if they don't tell you then you don't know I think TJC diamonds are mine diamonds. They have to tell you if they are lab on the telly but people have gone to jewellers and think they have a earth mined diamond and found out it's lab when sent for valuation, people are getting letters that have knowingly bought lab diamonds like of de beers saying saying Thank you for buying your Lab created diamond but sorry to say from now is your purchase depreciat in value
