What determines the price of loose diamonds? What is the difference between loose diamonds and finished diamond rings?

Diamonds have always been a very popular jewel, and the beautiful meaning of diamonds in love is recognized by everyone. When buying diamond rings, you will find that one type is customized loose diamonds, and the other is a finished diamond ring.

The price of diamonds is mainly determined by the 4Cs of diamonds. When looking at the overall score of a loose diamond, you cannot just look at the surface. This is the key to judging whether a loose diamond is good or not. The 4Cs of diamonds are the four factors of diamond color, clarity, weight, and cut. The weight accounts for 40%, and the rest accounts for 20%. The larger the diamond, the rarer it is. At the same time, the larger it is, the more valuable it is, especially diamonds over 5 carats, which are called pigeon eggs. The value is very high and costs millions or even tens of millions. When purchasing, you should understand the 4C parameters. Diamonds will have certificates that contain the 4C parameters of diamonds. It is recommended to balance the levels of each factor when buying, and not to have one factor too high or too low.

1. Price: Loose diamonds are cheaper than finished diamond rings of the same quality.

2. Style: Loose diamond styles are more personalized, while finished diamond ring styles are more in line with the public aesthetic, with more classic styles - the finished product can be obtained in 20 days.

3. After-sales service: Finished diamond rings can be replaced with ring settings and diamonds, which makes them easier to recycle. However, it is relatively difficult to recycle loose diamonds.

Generally speaking, the value preservation of loose diamonds is only 50 points or above. Before buying loose diamonds, it is recommended to think carefully before purchasing loose diamonds. The 4C standard is important, but the brand of loose diamonds is also very important. When buying, you must understand the reputation and reputation of the brand you are buying, the quality of diamonds, and other factors that determine the effect of the purchased loose diamonds. You must be discerning when purchasing. The grading of loose diamonds is very fine. If there is no big difference, it will be difficult for non-professionals to identify. Therefore, a loose diamond with an authoritative appraisal certificate is also purchased.

The price of a 1 carat loose diamond is mainly determined by the 4Cs of diamonds, namely the color, clarity, cut, and color of the diamond, as follows:

1. Diamond Color

Diamond color is like a filter. The more transparent and colorless it is, the stronger the light it reflects. Therefore, colorless and transparent is the best color. The grades are: D, E, F, G, H, IJ, KL, M, NO, PR, SZ. The later the color, the yellower it is. If you have high requirements for color, you can choose D, E, F, G, H, which is white and the color cannot be observed by the naked eye. If it is IJ or KL, it means a slight yellow color, and many people will still choose it, but if the diamond is large, you will feel the color. M, NO, PR, SZ are not recommended for purchase.

2. Diamond Clarity

Diamond clarity refers to diamond flaws, and the grade is determined by the size, number, and location of the flaws. The clarity grades are arranged from high to low as follows: FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, and I3. If you have high requirements for clarity, you can choose FL and IF, which are clean grades, while VVS1, VVS2, VS1, VS2, SI1, and SI2 are more popular choices. If the clarity is lower than I1, it is not recommended to buy.

3. Diamond Cut

Cutting is about symmetry and balance, which affects the fire and sparkle of diamonds. Excellent cutting can make diamonds emit dazzling light, so it is recommended to choose a better cut, ranging from "good" to "excellent".

4. Diamond weight

Weight is the main factor affecting the price, because the larger the diamond, the rarer it is, especially those above 5 carats. A 1 carat loose diamond is 0.2 grams, which is divided into 100 points, so a 1 carat diamond is also called a 100-point diamond.

In addition to the 4Cs of diamonds, it is also related to the added value of the brand. Different brands have different prices. Usually, a 1-carat loose diamond costs tens of thousands of yuan, and is accompanied by authoritative certificates such as IGI, GIA, EGL, HRD, etc. Some are national inspection certificates. Please pay attention to check when buying a 1-carat loose diamond.
