When earth-mined diamonds grew within the earth over 1 billion years ago, they were under intense amounts of heat and pressure. Over time, these crystals worked their way to the earth’s surface, later to be found via mining efforts. The natural shape of most diamonds is the octohedron, an 8 sided cube with pointed tops.
It is from this original form that most diamonds are cut. As you can see in this illustration below, diamonds are usually cut from the rough to maintain one large well-cut stone. The remnants are used to plan out other shapes and sizes to maximize overall value.
The most popular cut is the modern round brilliant, developed in 1919. This is the shape used in most traditional engagement rings and fine jewelry side stones. It has 57 facets (or cuts) all the way around the top and bottom of the stone. Prior to that, the single-cut was the norm, with a similar shape made of only 17 facets.
Any shape other than round is considered a fancy shape. The most popular shapes for engagement rings include Pear, Emerald, Square Emerald (Asscher), Radiant, Oval, Princess, Heart, and Cushion.
Over the past 5 years, diamonds that are not flat on top have gained popularity for a more alternative look. These are inspired by Rose cut diamonds from the 1800s, but with body shapes taken from traditional cuts such as ovals, rounds, and pears.
These shapes are often utilized with so-called “rough,” “salt & pepper,” or “icy” diamonds, which are diamonds with eye-visible inclusions or a noticeable body color.
The best way to decide which shape is right for you is to try each one on your hand. This will give you an idea of the size and dimensions that are most flattering to you.
