ThatвЂ™s why itвЂ™s vitally important to understand your diamond grading report. Diamond grading is opinion and there isnвЂ™t one consistent diamond grading standard that defines what a G color grade is or what a VS1 or VS2 clarity grade looks like. Because they are the leading labs, most of the certified lab-grown diamonds that you see on the market will have grading reports from one of these two labs.Д«ut these two labs donвЂ™t grade lab-grown diamonds (or mined diamonds) the same way. The two leading laboratories for diamond quality grading are the International Gemological Institute, most commonly known as IGI, and the Gemological Institute of America, known as GIA. Lab grown diamonds are graded in the same way as mined diamonds by the same diamond grading laboratories. Insurance companies use diamond certificates to determine the quality of replacement diamonds.

Grading reports also ensure you will receive the same quality replacement if your diamond is ever lost or stolen. Diamond certificates help you to identify your diamond if you ever have to repair or sell it.

Today, laboratories also confirm diamond origin, which is important because jewelers often canвЂ™t tell if a diamond is mined or lab-grown with ordinary gemological testing.Д«uying certified diamonds levels the playing field between retailers to help you compare diamond prices while you are shopping for a diamond ring, engagement ring, or other jewelry with significant diamonds. ItвЂ™s an educated assessment of a diamondвЂ™s exact quality characteristics, known as the 4Cs: color, clarity, cut and carat weight. A diamond grading report, often referred to as a diamond certificate, isnвЂ™t an appraisal, so it doesnвЂ™t include your diamondвЂ™s value. If you are buying a significant diamond or a diamond engagement ring, a grading report from an independent diamond grading laboratory is important because it gives you all the information you need to know about the quality of your diamond.
