The diamond review is a very delicate and complicated job. First of all, it requires that the hierarchical environment must be white and clean, and there must be too many other non -colored debris, otherwise it will affect the accuracy of the grades. Secondly, the hierarchical personnel must have a healthy and normal physiological condition, and they cannot be compared when they are sick and mentally poor, otherwise there will be deviations.
Third, the standard white light source (without fluorescence) is required. Other light sources or sunlight at different times, color grading is inaccurate.
Fourth, there must be standard sample stones. The size of the standard sample stone is generally required to be above 0.25 carats. It is best to have the same size as the diamonds to be graded. At the same time, the clarity of standard stones is generally above the SI level, and the cutting ratio is similar to that of the hierarchical diamond (the color of the standard stone is given by some authoritative gem mechanisms such as GIA).
Fifth, the diamond countertop is placed on the white paper on the white paper, and then the eyes are parallel to the waist of the diamond, perpendicular to the pavilion, and compare the color of the same part of the diamond as the style.
