http://www.thecanarydiamond.com - The Cut Refers to the facet proportions, symmetry and polish of a diamond surface. Each diamond that is precisely cut and defined as a diamond of ‘good make’ produces three key attributes : Brightness (Light reflections from a diamond), Fire (Dispersion into colors of the spectrum) and Scintillation (Light flashes when a diamond moves). It is a fine balance between cutting for maximum size or optimal brilliance. A diamond cut too thick will product unnecessary weight while if cut too shallow will allow for light dispersion through the sides. A standard round brilliant diamond will have 57 or 58 facets with the 58th facet being a ting flat facet at the bottom of the pavilion. This is different from the shapes of a diamond which includes Cushion, Emerald, Heart, Marquise, Pear, Princess, Oval  as they are often called fancy shape diamonds (See under Shapes). The Canary Diamond only accepts diamonds of the two highest grades for fancy shapes from the five classifications of diamond cuts, Excellent and Very Good. For Round Brilliant Diamonds, we only accept diamonds of the highest grade, Excellent.
