TECHNICAL SPECIFICATIONS AND GRADING
Emerald Cut diamonds are one of a family of step cuts, which are defined as stones with square or rectangular outlines whose facets are rectilinear and parallel to the girdle. Step cuts often have clipped corners. Emerald Cut diamonds don’t have a culet; instead, there is a keel which, like the keel of a boat, runs parallel to the longest edge of the stone and is the point where the two sides of the base meet.
Emerald Cut diamonds typically have 57 facets: 25 on the crown, 8 on the girdle, and 24 making up the pavilion. The table is a flat rectangle with rows of facets ‘stepping down’ from it.

BACKGROUND AND HISTORY
As the name suggests, the Emerald Cut was originally developed for cutting emeralds. With numerous naturally occurring inclusions, emeralds are easily damaged in the cutting process, so a cut with long, simple lines and truncated corners was needed to minimize chipping. The broad facets also allowed for greater depth of colour in emeralds and similar gemstones.
Following the introduction of the cubism art movement in 1925, jewellery styles started to reflect the geometric shapes and angular patterns we now associate with the Art Deco period. Gems were increasingly cut into triangles, pentagons and trapezoids, and step-cut styles such as the Emerald Cut made a refreshing change from the flowing, feminine, lacy designs popular around the turn of the 20th Century.

Emerald Cut diamonds can make stunning solitaire rings. They also often form the centrepiece of multi-stone settings. When choosing stones to accompany an emerald cut, avoid anything too sparkly which will make the central stone look dull.
Emerald Cut diamonds require a minimum four-pronged setting. For an Art Deco feel opt for a vintage style setting.
