European Gemmological Laboratory (EGL) is an independent international diamond grading laboratory responsible for certifying diamonds based on the 4Cs (cut, colour, clarity and carat weight).
A fancy diamond shape that has a step cut and is usually rectangular in shape with cut corners.
Refers to the proportions of a diamond’s cut. If ideal proportions and symmetry is achieved, the diamond cut will be graded as excellent meaning that there is maximum fire, brilliance and scintillation.
In clarity grading, an eye-clean diamond has no inclusions that are visible to the naked eye. In other words, the diamond will appear flawless to the naked eye. Diamonds that generally have a clarity higher than SI1 will appear to be eye-clean from inclusions.
