What are GIA, AGS, IGI and EGL Diamond Certificates? A diamond certificate (also known as diamond grading report) is an important document that tells the quality and authenticity of your diamond. It adds value to the price you pay for the precious piece of stone. A certificate rules out whether your diamond is natural (mined) or artificial (created in a lab) by terming it as GIA, AGS, IGI and EGL certified loose diamond. It is not only a validity report for your diamond but also a value-enhancement document. What Are The Diamond Grade Certification Labs? There are several gemological institutes in the market you can pick when you buy loose diamonds online. They serve the same purpose; they certify the diamonds you purchase. They follow a systemic and scientific procedure to evaluate the gems in the form of certified loose diamonds.
How Diamond Grade Certification Labs Differ? They differ depending upon the type of evaluations they do and several factors they take into consideration for the assessment. Some labs are rigorous in their evaluation metrics. Others have relaxed standards and show inconsistencies. You may try testing the same diamond in more than one of these labs with substandard evaluation metrics.
