The Gemological Institute of America is a much renowned and revered institution since 1955 that has a lions share certifying loose diamonds. It started the 4Cs of diamond gradation that stands for Cut, Clarity, Carat weight and Color. It also provides the International Diamond Grading System that is another way of a comprehensive analysis of grading the quality and authenticity of loose diamonds from the color range of D-Z.
GIA issues reports that also include the 4C’s, additional treatment on the loose diamonds, shape and cutting style, measurement and weights, and the proportion and finish of the diamond.
For GIA certified loose diamonds from 0.15 carats to 1.99 carats there is a “Diamond Dossier” which features the contents of the GIA report in a compact manner. Additional security is ensured for the certified loose diamond with a security number crafted with the help of a laser inscription on the diamond.
GIA laser inscription service is also used to inscribe on the girdle of the diamond, the GIA Inscription Registry, personalized messages, symbols, logos, anniversary dates etc. This helps in the identification of the diamond, branding of the retailer, personalizing of the loose diamond etc.
