Of the four C’s, the cut is perhaps the most important factor affecting the diamonds overall quality and beauty. A diamond’s brilliance is determined by how much light is reflected back to your eyes. Light enters the stone through the crown, which is the portion of the diamond which is above the girdle. The crown is made up of a table, which is the large flat facet on top of the diamond, and many crown facets. It then travels to the pavilion, The body, of the stone, which it is reflected from one side to the other and then back through the top and to an observer’s eye.
A well cut, well proportioned stone evenly reflects light within the stone, thereby producing an eye-catching, fiery spectrum of colour. A poorly cut diamond, on the other hand, allows more light to pass through or “leak” from the sides of the stone, which results in a lifeless appearance with reduced sparkle.
