Before we use any diamonds, they must be certified so that we can understand they are real. Whether the diamond is synthetic or natural, a certification will determine that the diamond is original and that we aren't getting a fake one. Several labs provide grading for the diamond's quality to certify them for use.
Out of all these labs, we know that IGI and GIA are notable and highly reliable. They have a specific and strict system to grade and ultimately certify. It is evident then that they will use the 4c's diamonds policy for their certification. This will look at the reflection, cut, size, weight, and also color. Mostly, a 4Cs standard means the color, cut, clarity, and the weight in carat of a diamond that is accepted globally.
For the certification, the lab party analyses the characteristics and checks whether the diamonds follow the standards. So, the lab has to be entrusted to make such reviews and grading. The final verdict before the document is given should be unbiased, with no intentions of sales. Lab diamond certificates will have various elements to show the features. In addition, they also contain the findings after experimentation with necessary tools.
Before a seller wishes for official documentation for their diamonds, they can send them to any lab. However, each lab has different criteria for grading so it won't be the same. According to reports and systems, we see that IGI is a more preferred lab for making the certificates. But we still need to see the reports if taken from multiple labs and analyze them to make a decision. Only then we can understand whether the documents are authentic and reliable.
Even though each lab has a difference in grading, it is better to get a certified lab diamond than an unauthorized one. Such diamonds maybe half the price, but not trustworthy. We can't tell with our eyes whether a diamond is real or fake, and worth our money. In that case, we need to get reviews from authorized labs and decide which one is the most reliable by checking diamond 4 c chart.
