triplex Triple Excellent Cut Diamonds

Cut ( Face up appearance - Brightness, Fire and Scintillation)

The first consideration in the Triple Excellent Grading.

 One of the most important elements of a diamond's appearance is the cut. The majority of diamonds are rarely cut to ideal proportions, but they have such high optical properties that most of them are still beautiful.

The way a diamond is cut will have the most significant effect on how the stone catches and interacts with light; what we generally think of as sparkle. A well cut diamond will reflect most of the light through the table (top surface) of the stone. If the diamond is cut too shallow or too deep then some of the light will escape out of the bottom or side.

Excellent Cut:   The diamond has high brilliance, sparkle and an even pattern of light and dark areas. Most of the light entering the diamond is reflected back through the table.

Polish (Craftsmanship)

The second consideration in the Triple Excellent Grading.

The facets of the diamond are polished to reveal the alluring sparkle that entices all of us. There are usually 57 or 58 facets on a diamond and each one must receive expert attention to ensure it reflects the optimum degree of light. Facets appear on the girdle, pavilion, crown and culet. The table is the top flat part of the diamond from where you see the alignment of all the other facets.

Symmetry (Craftsmanship)

The third consideration in the Triple Excellent Grading.

For a diamond to be graded symmetrically excellent, the  facets must be perfectly aligned. Symmetry marks the finish of the diamond. Any diamond in which the crown and/or pavilion facets are out of alignment would not be given an Excellent grading. In fact very few diamonds are graded as symmetrically excellent. The naked eye will not detect differences between good, very good or excellent diamonds as most are very beautiful. Only the highest quality grades of diamonds will be graded symmetrically excellent.
