The way a diamond is cut and polished is vital to the brilliance of the diamond in your engagement ring. The precision and delicacy of the cut dictates the maximum amount of light the diamond will refract and reflect. The better it has been cut, the greater the brilliance will be.
When a diamond is cut to good proportions, light is internally reflected from one facet to another and then dispersed through the crown, or top, of the diamond.
When a diamond is cut too deep, some light will escape through the opposite side of the pavilion, or bottom, of the diamond.
When a diamond is cut too shallow, some light will escape through the pavilion, or bottom, before it can be reflected.
A well cut diamond is comprised of facets with the correct angles, which are perfectly placed to maximize the diamond’s brilliance. It is the quality of the cut and its final polish that unlock the hidden beauty.
There are many shapes and sizes of diamonds, but whatever the shape or size, the cut is the only human element. A diamond cut to good proportions will have more value than one which is not.
