For these diamonds, the country of origin of the diamond is mentioned on the GIA certificate. To be able to trace a diamond from rough to cut, GIA collects and analyzes the physical measurements, spectroscopic data and imagery of the rough diamond before it is cut. An identification number is assigned to the rough diamond. The GIA later uses this data to scientifically match the cut diamond to the original rough diamond from which it came.

The price of the diamond is determined by the four main criteria, the "4C of the diamond": the weight, (carat), the purity (Clarity), the color (Color) and the quality of the size (Cut).
The weight (expressed in carats) is the factor that most influences the price of diamonds. The price of a 1 carat diamond is more than double the price of a 0.50 carat diamond of equal quality: in D IF quality for example it is worth about 6 X plus.
Our diamond price catalog allows you to familiarize yourself with the criteria determining the price of diamond, criteria that are explained in our diamond guide.
The diamond is the only precious stone to benefit from a standard system of universal graduation which makes it possible to establish diamond price tables according to its main qualities.
But every diamond, like every person is unique. A careful reading of everything mentioned in the certificate is necessary to be able to compare. "The best price is rarely the lowest price". The lowest price is often a hidden reason. To choose a diamond, you must understand its price.
The secondary parameters indicated on the certificate such as fluorescence, comments, mentions (example: size Good (Good), Very Good (Very Good)), the diameters with respect to the weight, also have their importance.
Our website i-diamants.com helps you understand the price of diamondsand make an informed choice. On each "Diamond Sheet" of our catalog, you will find the link to the visualization of the diamond certificate prepared by an independent gemological institute (GIA, HRD and IGI).
