Proof of diamond is necessary when proof is part of every evaluation but buying diamond is different from jeweler's evaluation. Proof of many diamond diamonds is documentary evidence of diamond attributes. There is no warranty, purchasing diamond will only pay quality. Therefore it knows precise grading for each of 4Cs color, cut, clarity and carat weight and diamond value respectively.
It is the other diamond compared to the value of any diamond needed to evaluate the information you gave the certification. It also makes it possible to make an intelligent comparison with the same watchmaker or another diamond.
The diamond certificate is issued by an independent gemology laboratory, not a jeweler. There are several grading laboratories, most notably the International Gemological Institute (IGI), Gemological Institute of America (GIA), American Gem Society (AGS), European Gemological Laboratories (EGL) and GemEx Systems.
When purchasing diamonds, first ask the sales staff about the properties and attributes of the stone. Watching is to purchase diamonds accompanying diamond certification. If you do shopping for comparison, be aware that the quality of diamonds carried by each jeweler will change depending on the store.
Diamond certification is also an indicator and about the quality of other diamonds, such as fire, brightness, scintillation and also called return light. These qualities show how the light goes back to the viewer when it is held stationary or at times movement. Proof also gives measurements of stone fluorescence. It also affects these factors, with beauty and glowing diamonds.
