Round Briliant Diamonds
The round cut is the most popular shape for diamonds and accounts for approximately 75% of all diamonds sold. The round diamond’s mechanics make it generally superior in the proper reflection of light to more fancy shapes which maximizes its potential brightness and sparkle.
Princess Cut Diamonds
Princess cut is the second most popular cut for a diamond. It’s a relatively recent cut having only been created in the 1960s. Sometimes referred to as a square-modified-brilliant, the princess cut combines the high degree of light return possessed by a round-brilliant cut with a distinctive square or rectangular shape.
Emerald Cut Diamonds
The step cuts of its pavillion and its large, open table give the emerald diamond its unique look. Emerald cut diamonds create a hall-of-mirrors effect by interplaying light and dark planes. Inclusions or body colour are often easier to see in emerald cut diamonds than in other cuts.
Like virtually all round-cut diamonds, the oval cut diamond is a modified version of the Brilliant Cut and thus possesses a similar fire and brilliance. However, the oval cut diamond has the added advantage of an elongated shape which creates the illusion of a larger size.
Much like a pillow, the cushion cut diamond combines a square cut and rounded corners. This classic cut has been around for almost 200 years and during it’s first century of existence was the most popular diamond shape, much like the round-brilliant of today. Recent refinements in its cut have led to a resurgence of this vintage stone’s popularity.
First produced in 1902 by Holland’s Asscher Brothers, the Asscher diamond is a forerunner to the emerald cut. The Asscher diamond is somewhat similar to the emerald cut but it is square in shape and has larger step facets, a smaller table and a high crown. This combination often creates more sparkle than the emerald cut.
Heart Shaped Diamonds
Heart shaped diamonds are a unique and unmistakable symbol of love and as such are popular in solitaire pendants as well as rings. The defined heart shape is best seen at larger than .50 carats. At any smaller than this the heart shape can be harder to make out, especially after set in prongs.
The marquise diamond’s shape can be likened to an american-football. Long and narrow, it creates the illusion of a diamond which is greater than its size and carat for carat the marquise diamond has one of the largest surface areas of any diamond-shape. This makes it a smart choice when trying to maximise perceived size.
