The diamond that we buy becomes all the more beautiful only after it has been well graded and cut and tested by labs of very high quality. After this lab testing is done, a proper gradation can be granted for that specific diamond.
Thus, diamond grading and certification and also the lab and rating are the perfect diamond guide to check and decide which diamond to buy and which to leave out.
From the time diamond started being marketed officially, its certification has become mandatory. This certification helps in deciding quality of diamonds and its final rates.
In this domain, much before GIA, if there is any organisation that holds place is the AGS, or American Gem Societys ratings. The AGS certified diamonds are best in quality and other aspects as well. Hence, one has to be very careful while choosing it since it gives a perfect standard for making that piece of rock all the more priceless.
