GRUNBERGER PRECISION CUT®

LIGHT REFLECTION
The Grunberger Precision Cut® was created with the desire to bring out the best in what a diamond has to offer. Through years of in-depth research on the relationship of cut proportions and light leakage, the Grunberger Precision Cut® succeeded in establishing the maximum fire and brilliance in a diamond.

Light leakage is caused by uneven proportions and poor symmetry.
If a cut is too shallow, light leaks out from the bottom. If its too deep, light escapes from the side.
Higher light leakage leads to a darker looking diamond, which eliminates its fire and brilliance.

FIRE & BRILLIANCE

Brilliance, or the brightness of a diamond, is what you see when white light reflects off the facets of a diamond.
When light travels through the crown facets, the reflections create small white flashes that are visible to the naked eye.
A well-cut round brilliant diamond looks brighter than a poorly cut diamond, even if the two are the same in size, color and clarity.
When white light travels through a stone and disperses through the crown facets, it creates a rainbow of spectral colors. That’s how a diamond gets its fire.
Through its consistency and high precision cutting, Grunberger Diamonds brings unparalleled brilliance to a diamond.
