The brilliance, fire and scintillation of a diamond is primarily determined by its cut, making it perhaps the most important, though most difficult, element of a diamond to evaluate. If a stone is cut too deep or too shallow, light will not be refracted back through the surface of the diamond, and the stone will lack luster. Properly proportioned stones will maximize a stone’s brilliance.

At Derco, we sell Gemological Institute of America (GIA) and American Gemologist Society (AGS) certified stones that give a full description of a stone's proportions, symmetry and polish. We also have a large selection of “Ideal” cut stones, which are cut to the most optimum proportions that maximize a stone’s beauty.
