Cut

Brilliance, fire and
scintillation are expressively diamond.

Nothing flaunts the splendour of a diamond like its cut. Top to bottom a diamond is comprised of a crown, girdle, and pavilion. If the pavilion angle is cut too deep, the stone will look dark. If it is too shallow, a diamond will look watery.

Well-cut diamonds will exhibit a breathtaking performance of light.

Many diamond experts are convinced that the optimal brilliance of a diamond is determined by one specific set of proportions. But cutting a diamond to ideal proportions has a cost. In some cases half of the crystal's weight is sacrificed. Consequently the diamond is sold at a relatively higher per-carat price.

The standard round-cut is by far the most popular cut. It has 57- 58 small, flat, polished surfaces called facets which account for the breathtaking sparkle.

Up to 60% of a diamond's cost is based on the cut.
