Our Grading Scale and Process

We only employ experienced GIA Graduate Gemologists, this is because we believe that the standards established by GIA are the most prevalent and reliable in the diamonds and colored stones industry. 

​

This results in us certifying the diamonds and/or colored stones used in jewelry using the GIA Scale 1-1. This means that we as a laboratory are not imposing our own standards, but instead relying on the established GIA standards. 

 

Examples of the GIA diamond scale can be seen below:
