How Shape & Origin Increase Diamond Price

Diamonds are one of the most highly prized gemstones in the world, known for their beauty, rarity, and symbolism. However, not all diamonds are equal, and some are far more valuable than others. 

In this article, we will explore the factors that influence the price of a diamond, with focus on the role that shape and origin play in determining its value.


The shape of a diamond is one of the most important factors that influence its value. The most common diamond shapes are round, oval, pear, marquise, princess, cushion, emerald, and radiant. 

The round brilliant cut is the most popular, accounting for around 75% of all diamonds sold. This is because the round shape is the most luminous at reflecting light, making the diamond sparkle and shine.

However, other shapes can be more expensive due to their rarity and uniqueness. For example, the heart-shaped diamond is highly sought after by romantics and is considered one of the most difficult shapes to cut, which makes it more expensive than a cushion cut of the same quality. Still, rounds take the cake by being the most expensive cut.


Similarly, the emerald cut is highly valued for its elegant and sophisticated look, and is often used for engagement rings and other special occasions.


The origin of a diamond can also influence its value. Diamonds are found in various locations around the world, including Africa, Australia, Russia, and Canada. However, not all diamonds are created equal, and diamonds that come from certain regions are considered to be of higher quality than others.


For example, diamonds from Australia's Argyle mine are highly prized for their unique pink and red hues, which are only found in this location.

Diamonds that have a well-documented history and come from a notable source can also be more valuable. Diamonds that have been owned by royalty or celebrities can be worth a premium due to their history and provenance such as the Koh-i-Noor Diamond estimated between $10-15 Billion.

In conclusion, the price of a diamond is influenced by a wide range of factors, including shape and origin. 


The shape of a diamond can affect its value, with rare and unique shapes commanding a higher price. Origin also plays a role, with certain mines being more renowned than others.

The 4Cs may also affect price, with larger, clearer, and more colorless diamonds being more valuable — with the exception of fancy color diamonds.
