Caroline Savoie Joaillerie Diamond Burst Wedding Ring 18k It is my pleasure to present to you the globally recognized diamond grading standards. First, some information about this beautiful precious stone that is the diamond. The diamond is the hardest natural material on both the Vickers and Mohs scale. Legend has it, that diamonds have been mined for over 6,000 years, but historically, the first diamonds were officially mined 3,000 years ago, in India. The four basic criteria determining the value of a diamond are: CARAT CLARITY COLOR SIZEThe “4Cs” are all important and interrelated.CARAT = Weight of the diamondCLARITY = Internal purity of the diamondCOLOR = Tint of the diamondCUT = Size and proportion of the diamond CARAT / WEIGHT The weight of the diamond is measured in carats and in hundredths of a carat. When talking about small stones, they are often said to weigh 10 points (0.10 ct), 15 points (0.15 ct), 25 points (1/4 carat), 50 points (1/2 carat), etc… Large stones being much rarer, the larger a diamond, the higher its relative price. CLARITY / PURITY The clarity of a diamond is defined by the relative inclusions discerned by an expert and specialist using a glass magnifying 10 times (10x). Here are the purity categories: F = Flawless, Completely without inclusion and external feature IF = Internally Flawless, Completely without inclusion, but has some external characteristics VVS1 and VVS2 = Very Very Slightly Included, Very very small inclusions hardly visible with a 10x magnifying glass VS1 and VS2 = Very Slightly Included, Very small inclusions visible under 10x magnification SI1 = Slightly Included, Small inclusions more easily visible under 10x magnification SI1 and SI2 = Slightly Included, Small inclusions easily visible under 10x magnification I1 = Included, Imperfect with difficulty with the naked eye I2 and I3 – Included, Imperfect easily visible to the naked eye COLOR / TINT The classification of shades begins with the letter “D”. The most wanted diamond is colorless or “D”. Seen with the naked eye, diamonds classified D – E – F are colorless. Diamonds graded G–H are white. Diamonds graded I – J are slightly yellow. There are pronounced color diamonds like blue, green, champagne, cognac, etc. These diamonds are called fancy diamonds. CUT / SIZE If the size of the stone is correctly proportioned according to the dimensions studied scientifically, the rays of light penetrate the stone and are returned by each of the facets, giving place to this magnificent scintillation that we know from the diamond.
