A finished diamond shows the skill of the cutter – who fashions the diamond to bring out the brilliance and scintillation – to make it sparkle from across the room. Technology can be used to assess the diamond’s light performance and hence the quality of its cut.

A diamond’s performance depends on the cutter’s decision of angles, placement of the facets, and the skill to place those facets precisely.

Once cut, getting a diamond to its full luster takes time and careful polishing. A poor polish can reduce the brightness and sparkle of a diamond.

The quality of the cut can increase (or decrease) the value of the stone up to 50% or more. When the cut is more precise, the stone is more captivating the eye.
