What Defines Diamond Quality? Understanding the 4Cs with Giliarto!

February 16, 2019

diamond

Each diamond is a special gemstone, a miracle of time, place and change. And each of them has unique qualities that determine its value.

Up until very recently, there was no official standard for diamonds' quality. The institution called GIA has come up with the first and globally accepted system of standards for describing diamonds: Color, Clarity, Cut and Carat Weight. Today, these are known as 4Cs of Diamond Quality and they are the universal method for assessing the quality of any diamond internationally. The establishment of the Diamond 4Cs ensures that diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.

As a creator of the Diamond 4Cs and the International Diamond Grading System™, GIA is not only a global authority but the world’s trusted source for an unbiased assessment. For more information on GIA and 4C's, please visit their website.
