More than white! What is the 4C+F of diamonds?
Diamond, the head of the five precious gems, symbolizes purity, innocence, eternal sparkle, and is the best symbol of love. The diamond ring has become the most important token of marriage. Diamonds are steadily increasing by 5%-10% or more each year, becoming a luxury that everyone loves. However, diamonds are valuable things. When people buy them, they are generally cautious. They shop around and think about it later. But, do you really know how to judge the quality of the diamonds you buy? As we all know, the internationally accepted diamond grading system is determined by the “4C†factor, which is the weight of the diamond (Carat), Clarity, Color and Cut. As long as consumers master the 4C standard of diamonds, they can greatly reduce the possibility of loss and deception. How is the 4C of diamonds judged specifically? Learn the following, you can also be a diamond expert. So, what is the 4C+F of diamonds? Carat carat weight is the weight unit of the diamond The international unit of measure for the weight of a diamond is "carat" and the English is "carat", often abbreviated as "ct". Carat weight is one of the diamond 4C standards. The weight of a diamond is the easiest measure of the 4C, and the carat weight is equivalent to the charm of a diamond. Diamonds of the same quality, the greater the weight, the more precious. During the cutting process, the normal loss rate of diamonds is about 50%-75%, that is, the diamond yield is only 50%-25%. The scarcity of diamond resources, the low output of large-grain diamonds, and the low yield of production and processing determine that large diamonds must have expensive value attributes. At the same time, in terms of jewellery use, diamonds must have a certain volume and weight to reflect the fascinating optical effects. Because small diamonds are too small to express their good brightness, they are often reflected in the process of grouping. Generally speaking, diamonds with a score of 30 or more can better reflect the brightness of the diamond. For the fire effect of the diamond, the weight of the diamond needs to reach 70 points or more in order to have a complete display. Therefore, the carat weight is the basis for the diamond to show beautiful optical effects. How many grams is 1 carat? What is the equivalent of 1 carat? How many grams is 1 carat? Now the standard 1 carat = 200 mg = 0.2 g; one carat is equal to 0.2 g. Diamonds weighing less than 1 carat are usually also measured in "Point", abbreviated as "pt". 1 carat = 100 points; 0.75 carats is also known as 75 points. "Carat premium" phenomenon The higher the grade of the diamond, the greater the effect of weight on the price. This is especially true for diamonds with a critical weight. In the case of the same color (color), clarity, cut, etc., as the weight of the diamond increases, the value increases geometrically, that is, the price is stepped. The price of the diamond = the base price of the carat square × carat. For the fraction of the integer, there is a "carat premium" between the prices of the diamonds. Even if it is only 1 point difference, the price of 99 points and 1ct is quite different. Diamond weight grading standard According to the habits of the diamond industry, below 0.05ct is a broken drill, 0.05ct-0.22ct is a small drill, 0.23ct-1ct is a medium drill, 1ct is a large drill, 10.8ct-50ct is a large drill, and 50ct or more is a registered name. Drill. Generally speaking, if it is not a rare color or other special places, only giant diamonds weighing more than 100ct will be eligible to be included in the history of world famous diamonds. National standards less than 0.2 carat are not graded. 0.2 to 1 carat can be graded either as a loose diamond or as a diamond, and diamonds larger than 1 carat must be graded in 4C according to the loose diamond classification criteria. COLOR color is the beauty of diamonds Diamonds can divide light into a colorful light and reflect it back to form a colorful flash. Just like through colored glasses, the color of the diamond acts as a filter. Thereby reducing the escape of reflected light. The lighter the color of the diamond, the stronger the color of the flash and the higher the color level. The color of the diamond is divided into two series, colorless series and color series. Common colorless series include colorless and transparent, nearly colorless and light yellow, and the color series includes dark yellow, blue, pink, black and so on. The diamond color grade is graded according to the color established by GIA of the American Gemological Institute, from “D†(transparent and colorless, starting with the first letter of Diamond) to “Z†(yellow). The color diamonds are ever-changing, and they are rare and expensive diamonds. The ordinary color grading system is not suitable for color diamond color grading. Colors of D, E, F, also known as transparent and colorless, are extremely rare and rare, and the difference between them depends on experts to distinguish. It is more common that the color is GJ, which is also called near colorless. Experts are easier to distinguish. The average person varies according to the individual color resolution. The color below K, also known as light champagne color, is easier to distinguish, and the same price is much cheaper.
