Cut

 

The classic way to cut a diamond, is the so called "brilliant" a cut with 57 facets (58 with the cullet). This type of cut enhances the diamonds brightness and "fire" in the best possible way. This optic effect is known as the "brilliance" of the diamond.
Since most diamonds are cut in the form of "Brilliant", people tend to confuse the diamond with the "Brilliant" cut.

Diamonds are fashioned into a number of shapes, depending on the nature of the  rough stone. The eight most popular shapes are Round, Marquise, Pear, Oval, Emerald, Princess, Radiant, and Heart.

The choice is largely a matter of personal taste. Whatever your preference, a well cut diamond is the work of a master diamond cutter, since it is the cut that enables the diamond to reflect light, creating scintillation and sparkle.

Every diamond regardless of its shape gets it brilliancy and scintillation by cutting and polishing the diamond facets to allow the maximum amount of light that enters through its top to be reflected and dispersed back through its top.

 If you are having a diamond mounted, write down the measurements of your stone. Measurements never change.

 
  

 

Measure the stone after it is mounted and verify that it matches the certificate.
