Diamonds - how to choose the right drill

A loose diamond is a diamond that has not been machined. Diamond is a very rare gemstone, and its noble temperament and gorgeous image are well recognized. In order to have a beautiful diamond, many people do not hesitate to spend a lot of money, thinking that it is very worthwhile. The price of loose diamonds sold by different brands in the market is generally different, and people have to re-examine whether the loose diamonds they purchased are “value for money”.

A diamond is actually a polished diamond. It is a simple crystal composed of carbon formed under the high pressure and high temperature of the earth. The diamond has a hard texture and is called the “King of Wanshi”. At the same time, it has a natural and pure color. The polished diamonds are bright and crystal clear. They are high-grade raw materials for making luxury jewelry, so they are expensive.

In order to maximize the "price" of the loose diamonds, many merchants will label the loose diamonds "Belgian cut" and "from South Africa". In fact, loose diamonds are an international standard commodity. They will not be produced by which company, and which company will produce the product.

South African diamonds are famous because South Africa is the world's largest diamond producer and is representative of diamond mining history. Diamonds were first discovered in India, others such as Angola, Zaire, Botswana and Namibia, and diamond production in China, Liaoning, Shandong and Hunan provinces. Belgium is a world-famous diamond cutting center. It is widely believed that the diamond cuts produced here are the best. The name of the “Belgian cut” is used by merchants to upgrade the grade of diamonds invisibly. Even so, as long as the loose diamond has a certificate issued by a professional testing agency such as GIA, it can be distinguished from the quality of the cut. And looking at the bare diamond itself, can not distinguish its origin and cut the city, but it is a means for businesses to attract customers.

To judge the price of loose diamonds, look at "4C" and see "certificate".

Diamond 4C is the weight of the diamond (Carat), clarity (Clarity), color (Color) and cut (Cut). To judge the value of the loose diamond, it is necessary to combine these four factors to evaluate. The value of the loose diamond is judged as follows: the weight of the diamond is proportional to the value. As the weight of the diamond increases, its value increases geometrically; the higher the purity of the diamond, the higher the value; in the yellow series, The closer the diamond is to colorless, the higher the value, the more rare the colored diamonds; the cutting, polishing and symmetry of the diamonds constitute the three indicators of diamond cutting, that is, the popular 3EX in recent years, the more perfect the cut, the higher the value of the diamond. The "eight arrows and eight hearts" diamonds, 99% are 3ex diamonds, but the 3ex diamonds are not necessarily "eight arrows and eight hearts" diamonds.

In addition to watching 4C, the diamond quality certification certificate is also an important factor reflecting the price of loose diamonds. In order to ensure the quality and authenticity of loose diamonds, it is necessary to have a certificate issued by a professional testing agency to avoid the loss of buying defective or fake diamonds. The internationally renowned diamond testing institutions have GIA, IGI, HRD, AGS, etc., while domestic certificates must have the CMA mark. With the guarantee of the certificate, the value of the loose diamond is truly realized.

In Greek, the diamond "adamas" has an unconquerable meaning and represents the eternal love fire. When modern people propose or marry, they will use diamond rings to represent the strong love, but the price of diamond rings is higher, while the price of loose diamonds is relatively real. Therefore, more and more people choose to choose loose diamonds.
