Emerald Diamonds


Similar to popular square shapes, the Emerald cut is simply an older and more elegant precursor to the faddish modern squares. It holds a sophisticated air and comes with a history that was taken from another gem altogether.

The Emerald cut is a step cut technique common to Emerald gemstones but not widely preferred in modern diamond cutting. At an earlier point in time, when tools and technology limited what could be achieved in diamond cutting, the Emerald cut was a logical procedure to follow. Emerald cuts vary in shape from oblong to square, and always with the corners substantially mitred to protect the stone from chipping. The miter gives cause for minor confusion in the industry in that some sources will refer to an Emerald cut diamond as an octagonal stone, and with good reason. Emerald gemstones are always referred to as octagonal in shape so it follows that a diamond being referenced as an Emerald should also be referred to as octagonal. Regardless of shape description, an Emerald cut diamond has a large flat surface and absence of facet angle refraction.

There are reasons a modern day diamond cutter would choose to make an Emerald cut over a brilliant cut. First would be to retain more weight, in fact, sufficient extra weight to offset the lower per carat price commanded by Emerald cuts. Secondly, a cutter would chose an Emerald cut if the rough stone is of a colour rich enough to benefit from the colour purity of a non-faceted diamond.

The inspiration for cutting diamonds in the Emerald shape came from the popular green gemstone of the same name. Real emeralds are most always found in their rough shape as octagons and lend themselves quite perfectly to cutting in an octagon shape with little carat weight loss and good retention of colour saturation. This does not always make good sense for rough diamonds, even if it is a relatively quick and easy type of cut to make and polish. However, before technology paved the way for quality square cuts, diamonds were fashioned in the tradition of the emerald gem.

A diamond cut in this manner can run the risk of being too flat and may lack ability to reflect light, leaving a more dull and glassy impression. Imperfections and marks are more obvious on these because of a potential lesser colour quality.

Investors who enjoy vintage pieces or who appreciate the time-honoured method of Emerald cutting would best benefit from this choice. A buyer who is interested in diamonds that are created with these older cutting methods would surely appreciate the classic presentation. In essence, this cut is the original square and carries great tradition and antiquity.
