The Modern Round Brilliant Cut Diamond:

	The modern round brilliant cut diamond has 58 facets. The top portion of a round brilliant cut diamond is called it's CROWN and consists of a large octagonal facet called a TABLE, which is surrounded by eight triangular STAR FACETS which point downward towards the edge of the diamond; eight kite shaped BEZEL FACETS which radiate from the table corners to the girdle edge; and sixteen triangular UPPER GIRDLE FACETS arranged in pairs which circle the perimeter of the crown.
	The GIRDLE is the edge of the stone that rests between the upper and lower portions of a round brilliant cut diamond.  The girdle resembles symmetrical ocean waves running in an upside down and right side up position aligned evenly with each other along the edge of the stone where the top and bottom section of the round brilliant cut diamond come together...  Girdle thickness can vary from extremely thin to extremely thick with our preference being from thin to medium or medium with a faceted edge...  To have a faceted girdle on a round brilliant cut diamond merely means that the cutter added extra facets (edges) on the girdle edge to reflect just a little more light...
	The lower portion (bottom half) of a round brilliant cut diamond is called the PAVILION.  A small facet located on the bottom of the diamond is called the CULET and finishes off what would otherwise be a sharp and brittle point. From the culet, there are eight elongated, kite shaped facets called PAVILION MAINS which radiate up towards the girdles' edge. Between each pavilion main is 1 of 16 elongated, triangular LOWER GIRDLE FACETS which are arranged in pairs.
