CARAT Carat Stones are sized by weight. To ensure it is easy, feel of diamonds as with regards to a dollar bill. Every dollar can be broken down in 100 cents, and every carat diamond can be broken down into 100 points. As an illustration, a quarter carat diamond, popular in diamond stud earrings would be the same as 25 point diamonds. A one and 1 / 4 carat diamond would be like a diamond weighing 125 points exactly the same. COLOUR Once more viewing the necessity to get a universal program, the GIA developed the diamond colour grading scale, making use of the letters D - today Z, which is most widely accepted. Diamond are rated under very exact viewing conditions and often compared to diamond of a known color grade to ensure not many variations within a color grade. A diamond absent of color is grade 'D' and the more color that is contained in the diamond, the further along the alphabet it is grade journeys. Diamond with rank 'Z' will have a light yellow or brown tint, and hence will not reflect light as well as a colorless diamond. Elaborate coloured diamond, although most are irradiated and colour improved, do not follow this grading scale, and often are more beneficial because when naturally colored they are extremely uncommon. CLARITY Clarity is the last of the 4 c s and describes the lack of or presence of internal and external imperfections as seen under 10x magnification. Virtually all diamonds contain minute traces of non - crystallized carbon or small non - diamond crystals, because diamonds are crystallized carbon atoms under tremendous pressure and temperature. The number, size, place and nature of these imperfections found will decide the clarity level regarding the diamond. Regarding the appraisal of the particular stone, the less imperfections found, the more valuable it will be. CUT Cut Cut is of critical significance to a stone.
