Diamond Reports, also known as Diamond Certifications, are documents that define the unique characteristics of individual diamonds in a universal and understood "language" helping individuals understand the grading of a diamond and its features. These documents are assigned by many laboratories that employ teams of gemologists to examine each individual stone with advanced techniques and equipment.
While diamond certification doesn't neccesarily dictate the value of an individual diamond, it does effect the conceived perception of the diamonds actual quality, which depending on the particular laboratories consistency and reputation can mean a large difference in actual value.
The "language" utilized today to describe the unique characteristics of a diamond were developed by the Gemological Institute of America (GIA), allowing professionals and consumers the ability to understand the factors that may effect the overall look of the diamond, as well as to understand whether or not any treatments are present and whether or not the diamond is natural or synthetic.
Many major laboratories exist in many countries around the world, and while most practice and operate by solid ethics and standards, certain laboratories who struggle to find a place in the industry, have been known in the past to bend the standards of diamond grading and gained a reputation for over-grading diamonds.
