When a diamond is exposed to light, it reflects white light toward the viewer. The visual effect is what is called diamond brilliance. The brilliance determines the sparkle and brightness of a diamond. A perfectly cut diamond allows light to be reflected by the viewer, while a diamond-cut at a shallow angle will reflect less light. Direct light and light obstruction determine a diamond’s brilliance

Determining Diamond Brilliance 


A round diamond has 58 facets, while a perfectly cut diamond will have plenty of light reflections. As the light enters the diamond, it is divided, and the physical facets reflect right from different directions. The size of the facets depends on the number of physical facets and the number of times light is divided. Therefore, it is safe to say that the optics of a diamond is determined by the size, number, and arrangement of virtual facets. 


The contrast in a diamond is the difference between black and white when light is reflected. The impact of contrasting detectable edges enhances diamond brilliance. A diamond with less contrast usually doesn’t have black patterns. On the other hand, a diamond with more contrast is likely to have more scintillation. 


A diamond’s cut will affect its brilliance. A poorly cut diamond will have the least degree of shine and reflection. A cut that is too deep or too shallow will not allow light to pass effectively and be reflected by the viewer. A diamond with a high cut will show the most brilliance. 


Scintillation is the play and contrast of light and shadows in a diamond. A quality cut diamond has a clear balance of light qualities in light and dark areas.
