What does the diamond ring GIA certificate mean What does the diamond ring GIA certificate mean? Diamond ring GIA refers to the diamonds on the diamonds on the diamond ring with a GIA certificate diamond. The diamond ring certificate can be seen from the weight, color, clarity and cutting of the diamond. Now look at what the diamond ring GIA certificate means. Ip diamond ring GIA certificate meaning 1. What does the diamond ring GIA certificate mean GIA is the abbreviation of the American Gem Institute. Essence The GIA certificate issued by GIA, the weight, color, clarity, cutting of the diamond, 4C information, etc., is 4C information to conduct a comprehensive evaluation, so as to judge the quality of a diamond quality. . How to see the GIA certificate of the diamond ring The diamond ring certificate can be used as the weight, color, clarity and cut of the diamond. 1. The weight of diamond
The unit that measures the weight of diamonds is called "carat". Generally speaking, the conversion relationship between its units is 1 gram = 5 carats, 1 carat = 100 point. The greater the weight of the diamond, the higher the value, the more value -preserving and value. Especially for diamond rings above one carat, this value -preserving and value -added performance is particularly obvious. 2. The color of the diamond The color standards to measure the color of the diamond in the GIA certificate are only suitable for gem -grade white diamonds, which is not applicable for color diamonds. Generally speaking, the closer the color of the diamond is, the better the quality of the colorless. The more the color is closer to the pale yellow or yellow -brown, the worse the quality is. The GIA certificate divides the colors of these diamonds into 23 levels from D to Z to distinguish the quality differences between them. D Glass: The completely colorless diamond is the best in the jewelry industry. The quality is very high, the quantity is scarce and extremely precious. E -Class: The color of the diamond is second only to D -level. Only professional instruments can be detected to detect trace elements. F -grade: For a small amount of jewelry appraisal experts, some trace pigments can be observed with the naked eye G — H level: The naked eye observation cannot notice the hidden pigments. When coming to compare, the color contained in the color will appear. I -J: The fine color can be observed through the naked eye. K — Z: The color contained in it can be obviously observed with the naked eye, which is a diamond with poor quality. 3. The clarity of diamonds
The clarity of the diamond refers to the amount of impurities or flaws inside or surface of the diamond. According to the rating principles of the GIA certificate, we can divide it as FL, IF, VVS1-2, VS1-2, SI1-2, I1-3 in total 11 levels. FL level: completely flawed diamond. IF level: There are no flaws inside the diamond, and there will be small flaws on the surface of the diamond. VVS level: Use ten times the magnifying glass observation, there are extremely small flaws inside. VS level: When using a ten -fold magnifying glass observation, there are small flaws inside. SI level: When using a ten -fold magnifying glass observation, there are obvious obvious flaws inside. I: Use a normal magnifying glass or the naked eye to obvious internal impurities, which is a poor quality diamond. 4. The cutting of diamonds A good diamond cutting allows the diamond to fully play its sparkling and fire color, so that the diamond overall looks light. The more inferior cutting work will make the diamond's dim light losing the original glory. The GIA certificate is divided into five levels of diamonds. E -Class (ideal cut): Diamonds can almost reflect all the beams that enter the diamond. VG grade (very easy to cut): Diamonds can reflect the beam that enters the vast majority of diamonds. G -grade (good cut): Diamonds can reflect most beams that enter the diamond. F -grade (generally cutting): Diamonds can reflect the beam that can be acceptable in the diamond. -level (differential cut): Most of the light beams of the diamond will slip away from the bottom of the diamond, making the overall diamond look dull and dull. In addition to the GIA certificate, there are other appraisal certificates for the quality of diamonds to refer to it. Everyone learns to see the diamond identification certificate and can easily know the quality of the diamond. Diamond ring GIA certificates What are the meaning of pure dry goods!
