Diamonds are very rare and expensive jewels. In addition to the diamond ring for marriage, many daily jewelry are inseparable from diamonds. Because of the rarity and high price of diamonds, many fakes have appeared, so many people who buy diamonds want to see the identification certificate of diamonds, among which EGL certificate and GIA certificate are two common ones.

E.G.L is the abbreviation of European Gemological Laboratory. EGL uses the most advanced tools and technologies to show the real data of diamonds. In the world, EGL appraisal has a certain professional status and popularity, and it is an authoritative diamond appraisal certificate. EGL certificate contains the physical characteristics of diamonds, such as weight, color, clarity, size, polishing and symmetry. EGL does not sell diamonds and precious stones, nor does it evaluate the value of diamonds.

From June 5, 2009 to 2009 10, EGL Asia Lab set up a business contact center in East China in Shanghai, China to further enter the Chinese mainland market. Since then, EGL has gradually flowed into the China market and started to be known to consumers with its internationally recognized status. EGL certificate is favored by small diamond retailers in this department because of its relatively cheap appraisal service and the title of "international certification".

The certificate of diamond appraisal has now almost become the ID card of diamond, and the certificate issued by an authoritative and reliable certificate appraisal institution has also become a necessity for diamond lovers to wear and invest.

Previously, many internationally renowned diamond appraisal institutions, such as American Gemological Institute (GIA certificate), American Gemological Institute (AGS diamond certificate), Belgian Diamond High Council (HRD certificate) and International Gemological Institute (IGI certificate), etc., starting from September, Rapaport Group, which established the international diamond price list, will no longer accept the EGL certificate of European Gemological Institute, and the price is1/kloc-.
