The most important parameter for determining the price of loose diamonds is the grade of loose diamonds, and the standard for determining the grade of loose diamonds is 4C standard, which means:
First, cutting, cutting is the most important factor in determining the price of loose diamonds, and it is also decided by the person in charge of cutting. Good cutting will create higher value. Cutting is mainly divided into excellent cutting and very excellent cutting. Good), good cut (good), medium cut (medium), medium cut (fair) and poor cut (poor).
2. Cleanliness is subdivided into IF (representing the cleanest and least visible defects) and VVS, VVS 1 and VVS2, VS 1 and VS2, SI 1 and SI2, and I1. Among them, the larger the subdivision value, the lower the clarity, and the easier it is to see the defects!
Third, the weight, regarding the weight, I think everyone should know that the heavier the diamond, the more expensive it is!
Fourth, the color is subdivided into D, E, F (D, E, F in the F(4C standard, also known as transparent and colorless, is also an extremely rare diamond in the world! )

Price reference and details are subject to the current market price (the higher the letter, the more precious it is).
G, H, I, J(G, H, I, J is also called nearly colorless, and there are many in the market), K, L, M(K, L, M is also called light yellow, which can be distinguished by careful observation with the naked eye).
No, no, ... to Z (from n to z, also called light yellow. The closer to z, the yellower the color. The international quotation sheet for loose diamonds only contains parameters from D to M! )
The price of loose diamonds is directly related to the color discrimination. In D to Z, the higher the ranking, the higher the price. The higher the ranking, the lower the price. Simply put, the closer a loose diamond is to colorless, the more transparent it is and the more expensive it is! On the contrary, if it is found to be a little yellow, the price will be much lower!
Ordinary consumers have never been exposed to the international quotation of the original stone before (if they are lucky, they can still see it online now), but today I will tell you a calculation method, which can also calculate the purchase price of this original stone. That is, diamond pricing = the unit price of diamond weight range and the unit price of color grade are coordinated with the unit price of clarity, x the weight of loose diamonds x the exchange rate (generally 6.550)X discount. The above is my brief introduction to the international quotation of loose diamonds, hoping to help you!
