Diamond Cut

 Various Diamond Cuts'Cut' refers both to the number of facets of a diamond, and their relationship to each other.   Each facet is precisely cut and defined.  Without perfect precision, a diamond would hold light rather than bend and reflect it making the diamond not nearly as beautiful. The allure of a particular diamond depends more on cut than anything else.

While it can be very difficult to analyze or quantify, the cut of any diamond has three separate attributes.  The first, brilliance is a measure of the total light reflected from a diamond.  The second attribute, fire is the dispersion of light into the colors of the spectrum.  The third, scintillation is the flashes of light, or sparkle, when a diamond is moved.  At Powers Jewelry Designers,  you will see some of the most brilliant, exciting diamonds you will ever see at prices you won't find anywhere else.

An understanding of diamond cut begins with the shape of a diamond.  The most common shape is the standard round brilliant cut.  Other cuts are known as fancy shapes.   Fancy cut shapes include the marquise, pear, oval and emerald cut diamonds.  Hearts, cushions, triangles and a variety of others are also popular.

The proportions of a diamond refer to the relationships between table size, crown angle and pavilion depth. A wide range of proportion combinations are possible.  The proportions of Cut ultimately affect the diamond's interaction with light.

The distance from the bottom of the girdle to the culet is the pavilion depth.  A pavilion depth that is too shallow or too deep will allow light to escape through the sides or the bottom of the stone. A well-cut diamond will direct more light through the crown creating the sparkle that is the most desirable.
