Expert jewelers and gemologists advise customers to buy rings with AGS or GIA diamond ring certification. The Gemological Institute of America (GIA) is regarded as one of the most consistent and respected grading entities in the world. So, if you wish to stay away from faux or fake diamond rings, it is best to look for an AGS or GIA certified diamond ring.
GIA certified diamonds are to be trusted, mostly because a well respected organization has signed off on the idea that they are quality jewels. GIA also makes a habit of putting micro-laser inscriptions on the gems it grades.
