The cut of the diamond : its evolution

The cut of the diamond : its evolution

Although the diamond has been known for over 2000 years as a precious stone, the first cut only goes back to the 14th century. Only the overhanging of angular stones was cut in order to improve the optical effect. 

This cut has dramatically evolved over the course of the last few centuries. 

Evolution de la taille du diamant

The point cut, named after the shape of its crystal, it is the first authentic diamond cut. 

In the 15th century, the table cut appeared. 

In the middle of the 16th century, the “table cut” was improved through the evolution into a sided stone called old cut which has a polygonal table. The top and bottom surfaces are called facets and there are 18 of them. 

Around 1650, at the request of Cardinal MAZARIN, a new cut was created which had 34 facets : this stone was called the Mazarin cut

Towards the end of the 17th century, the Venetian Vincenzo PERUZZI managed to cut a diamond to 58 facets. The PERUZZI cut was close to the modern round brilliant cut, both because of its almost identical number of facets and its overall proportions. 

The diamond only reached perfection with the round brilliant cut also known as the modern cut. This cut was perfected in 1910 based on the old European cut developed during the previous century.
