If you want to select an'affordable' 1 carat loose diamond from the low-clarity large diamonds, let's find out with the author. 1. How to calculate the price of a 1 carat loose diamond The price of a diamond is clearly divided in weight. For example, the price of 0.99ct is much cheaper than the 1.0ct diamond. For loose diamonds above 1 carat (including 1 carat), the price is calculated by multiplying the square of the weight by the price of the 1 carat loose diamond. 2. Specific analysis of specific problems It is quite abstract to talk about the price of a 1 carat loose diamond without specific objects. But we know that the value of a diamond is expressed through the '4C' standard. The price of two diamonds with the same weight of 1 carat may vary greatly due to the influence of other 3Cs. Therefore, the color, clarity, and cut of the diamond are also very important for the price of 1 carat loose diamonds. Therefore, when you face a 1 carat loose diamond, you must consider the weight, color and cut of the loose diamond, and finally determine the price of the 1 carat loose diamond. Third, how to price finished carat diamonds For a diamond ring that has been securely mounted, in addition to the cost of the loose diamond, the price also includes the metal used, production and management costs and profits, etc. Therefore, the cost price of the inlaid diamond ring u003d the price of the loose diamond + the cost of precious metals + labor costs. The choice of setting also affects the price of the entire carat diamond ring. At present, platinum and k gold are the most popular setting materials. Fourth, how to choose an'affordable' loose diamond from a low-clarity carat diamond The first key is to try to ensure that the big diamond has the most brilliant sparkle. The clarity of the diamond does not actually affect the sparkle of the diamond, as long as the cut is maintained at a standard. In the'GIA' diamond evaluation system, there are many items related to cut, but there are only three items that are really critical. These are'Cut (comprehensive cut index)','Pol (polishing index)' and'Sym (symmetrical). Sexual indicators)'. If the customer can ensure that the 'comprehensive cut index' reaches 'EX (excellent)' when purchasing carat diamonds, even if the other two cut indicators are only 'VG (very good)The diamond has a very good fire. The second key is to control the color, size and location of the flaws in the diamond. VS and SI grade diamonds can clearly contain 'slight flaws' in the standard. The smaller the flaws, the lighter the color. It should be an absolute choice. To prevent flaws from being amplified by reflection due to light refraction, it is necessary to facilitate effective concealment with prongs during inlay. The third key: Be careful not to let the selected carat diamond have fluorescence that affects the appearance. Diamond fluorescence is divided into white, blue, yellow, purple, etc. Among them, the strong fluorescence can be observed with the naked eye, while the low-level fluorescence needs to be exposed to ultraviolet light to show up. The fourth key: It is best not to buy carat diamonds with a stone weight below the lower limit of the grade. For example, in the 1.00 carat to 1.24 carat grade, it is best not to buy the 1.00 carat weight. Because carat diamonds are a commodity that is priced by grade, the price of a stone will rise a lot if it is higher. 5. The 1 carat loose diamond becomes the new favorite of investment 1.
