Round Cut Diamonds
75% out of all the diamonds that are sold are represented by this category making it the most popular diamond shape. Round diamonds are generally considered better than fancy diamond shapes because it reflects light better and improves its potential brightness. Almost all round diamonds are brilliant-cut, which means that it has 58 facets and 57 when culet is absent.
Due to the following reasons round diamond cost more on a per carat basis than fancy shapes: The demand for round diamonds is very high, relatively low yield because during the cutting (rough diamond) process more of the rough stone is lost hence the cost of the retained carat is higher.
Princess Cut Diamonds
Betzalel Ambar and Israel Itzkowitz were the first creators of the princess cut diamond back in 1980. It is known as one of the most popular fancy cut, and is typically famous for engagement rings. Just like the round cut diamonds princess cut diamonds are favorable because of its flexibility and its versatility. Princess cut diamonds have a slight lower price per carat than round cut diamonds.
Asscher Cut Diamonds
The then famous for cutting the world’s largest rough stone (the Cullinan) Asscher brothers from Netherlands were the first to have produced the asscher cut diamond in 1902. This cut gained huge popularity in the 1920’s and eventually faded. However, it rose to prominence in the early 2000, a 100 years after it was invented only this time with some modifications like better cut which brought great brilliance to the diamond with this cut.
Radiant Cut Diamond

Emerald Cut Diamond
This shape was invented whilst cutting the gemstone- emerald that is why t is given this name. The emerald cut diamond is uniquely created by its large table which is open and the step cuts of its pavilion. The diamonds with emerald cuts produce a hall of mirrors effect rather than the sparkle of a brilliant-cut. The inter play of light and dark planes create this effect. Albeit it appears less fiery, the heightened lines and the theatrical flashes of light is what gives a graceful appeal to an emerald cut.
Marquise Cut Diamond
The name marquise is derived from Marquise of Pompadour. It is believed that the king of France Louis XIV had a diamond made which resembled the face of the marquise. These diamonds are long and narrow shaped due to which they tend to create an illusion of having a size bigger than it actually has. The marquise diamonds makes the finger of the wearer look slimmer and longer than it actually is.
