There are very few people selling fake goods now! To survive! The real goods market is very competitive! Major brands will not permanently damage their brand reputation for temporary benefits!
No matter where you buy jewelry, you must buy a certificate! GIA certificate is preferred! International certificates such as IGI and HRD are better! At least have a certificate of national inspection! And can make you re-examine!
Don't covet too much cheap! It's a truth to get what you pay for! If the price is too cheap, be careful not to be a pie but a trap!
I hope to solve the problem!
