The scale of a diamond might also be an element. Incredibly small (< 0.02 carats [4 mg]) diamonds—generally known as melée—tend to be given simplified cuts (i.e., with fewer aspects).

4°. Two observations is often made: In the event the pavilion is just too shallow, light-weight meets the pavilion aspects in the significant angle, and is refracted (i.e., dropped) from the pavilion base into the air. In the event the pavilion is simply too deep, light-weight is initially reflected outside the house the critical angle on a single aspect with the pavilion, but meets the opposite aspect in the important angle and is then refracted out the side in the stone.[four]
