Colour, Clarity, Cut & Carat


The first C of the 4C's of Diamonds. All International Gemmological institutes have established a scale of 23 letter grades indicating a diamond's colour. D,E, and F are the highest and rarest grades. G through J are nearly colourless. K,L and M are faint yellow. N through R are grades of very light yellow. And S through Z are considered light yellow. There are other fancy colors of diamond, such as blue, pink and yellow. We hope this has helped you to better understand diamond colour.


The second C of the 4C's of Diamonds. Using a jeweler's eye glass loop at 10 times magnification, a trained eye can detect identifying characteristics which affect a diamonds clarity. The most common are internal flaws called inclusions.Some diamonds have external flaws, which are called blemishes. The size and location of these characteristics determine how the diamond is graded on scale as: FL - Flawless, VVS - Very Very Small inclusions, VS - Very Small inclusions, SI - Small Inclusions. We hope this has helped you to better understand diamond clarity.


The third C of the 4 C's of diamonds. There are many different shapes of polished diamonds, such as Round, Pear, Marquise etc. But, while these are often referred to as cuts, this is not what is meant by the third C. From a gemologist’s point of view, the cut of a diamond is what determines its brilliance. Unlike the other three C's, a diamonds cut has no single defined standard. Rather it is a set of measurements which determine the relationship between its dimensions, finish and light performance. Whatever the diamonds shape is, its width and depth determine how light travels inside. The more successful a diamond cutter is in balancing these considerations, the more valuable the stone will be. Even a colorless and flawless stone can be significantly diminished by a poor cut, because it will lack visible brilliance. We hope this has helped you to better understand a diamonds cut.


The fourth C of the 4C's of Diamonds. Among all of the characteristics of a diamond, the carat is the most known and probably the most easily observed. A carat abbreviated CT, measures the weight of a diamond. One carat is one fifth of a gram, meaning a 5 Carat diamond weighs one gram. Since larger diamonds are rarer than smaller ones, the price per carat increases with its weight. In other words, two one carat diamonds will cost less than a two carat diamond of the same grade. Although carat weight mostly determines a diamonds apparent size, what really determines its appearance are the other three C's. So while a larger diamond might be more costly, it may not be as beautiful as a smaller one. We hope this has helped you to better understand a diamonds carat measure.
