Diamond Grading
 

In order to grade the clarity of a diamond, it is necessary to observe the number and nature of any internal characteristics in the stone as well as their size and position. This analysis is carried out using the IGI scope and a loupe 10x under the experienced eye of laboratory gemologists. A diamond is said to be "Internally Flawless" when it presents no internal defects under 10x magnification.
