If you're all about glamour, this is your diamond. A rectangular shape with long, lean and elegant facets extending down the sides, it's the large table, which is the flat part on top shows off the clarity of the diamond better than any other shape. The emerald cut does not have the brilliance of a round or princess diamond but is exudes quiet sophistication and sleek confidence. Born in the art deco period, the emerald diamond shows off long, glamorous lines with its rectangular shape with cut corners that resemble stair steps. Step cut diamonds create flashes of light that reflect light like a hall of mirrors. This faceting creates light and dark planes within each facet or step. An emerald cut diamond is often called a step cut, and its name was taken from the most popular shape for emeralds in the 1920s.
