A diamond’s shape refers to its physical form. It is clearly not a part of the 4Cs but is one of the most important factors when choosing a diamond. The distinction between the diamond cut and the diamond shape might be confusing at first. The shape of the diamond is its physical appearance but its cut refers to its ability to reflect light, its facets, and angles. The most common shapes of diamond include asscher, brilliant, cushion cut, emerald cut, heart, marquise, oval, pear, princess cut, and radiant cut.
A pear-shaped diamond is a combination of the round and marquise cut diamond with a tapered point at one end. A pear-shaped diamond should be perfect in terms of symmetry. The point of the tapered end should match with the apex of the rounded end. The diamond contains 58 facets, allowing light to pass through it in the same way as the round shaped diamond.
This is a popular style known for its precision and beauty. The emerald cut is named so because it is cut in a shape that was originally a style for emeralds. It might not possess the brilliance of the diamonds cut in a kite or triangular shape but its pure ice-like clarity makes up for the brilliance. This style of cut is also called the step-cut.
It is a modified version of a brilliant cut diamond only with a cleft at the top. A heart-shaped diamond is unique and a symbol of love, popular in forms of solitaire pendants and diamond rings. Symmetry is an essential factor while selecting a heart-shaped diamond. The division between the two lobes should be evident. If you want a bigger stone, avoid going for heart-shaped diamonds that weigh less than 0.50 carat as they appear small and even smaller when set in prongs.
It is a modified brilliant cut diamond, long and narrow in shape considered ideal for engagement rings. Its long and narrow boat-like shape creates an illusion of it being greater in size. Marquise-shaped diamonds have one of the largest surface areas, which is a great option when one wants to magnify the appearance of a diamond.
