The ideal shape for a diamond to attain the optimum light dispersion is the round brilliant cut. Quite simply put, the round shape is symmetrical, each facet is perfectly aligned. A Round Brilliant Cut Diamond has 58 facets, 33 on the crown(top) and 25 on the pavilion(bottom).

As the light enters the diamond, it refracts through the stone, reflects off each facet and disperses parallel to its entry path. Imagine thousand of beams of light entering the diamond and brilliantly emanating from the stone. This is called Brilliance or Scintillation
