Step Cuts - Square, Oblong or Rectangle Diamond Shapes
Many Square, Oblong or rectangular diamonds are 'Step cut' or 'Table cut' which the cutting style is often used in Marquise, Emerald and Oval diamond shapes. The facets on a 'Step cut' are cut in steps. The crown, pavilion, and the table are all cut in rectangular facets. These diamonds are bright, clear and shiny in appearance as its facets usually span the length or width of the stone, the facets gradually decreasing as they approach the table producing Square, Oblong or Rectangle diamond shapes.
Fancy Cuts and Shapes
Fancy cut diamonds and other stones include the Emerald, Marquise, Heart, Oval, Pear and Princess cuts and shapes. Fancy Cuts and Shapes are all ways of cutting a diamond or other stone to maximize the carat weight. A rough diamond which might only yield a half carat in a Brilliant Cut might yield another 50% if cut into one of the above shapes. Fancy Cuts and Shapes allow the cutter to use the best attributes of a rough diamond and eliminate inclusions and blemishes.
