Do you have more questions? In this article, we will delve into the history, technical characteristics, practical differences, and tips for identifying and valuing these unique jewels.
What is a diamond?
A diamond is a gemstone composed of pure carbon that crystallizes in a cubic system. This process occurs in the Earth’s mantle under extreme pressure and temperature conditions, making it one of the oldest and hardest substances on the planet.
Properties of a diamond
- Extreme hardness: It is the hardest known natural material, which means it can scratch any other material but can only be scratched by another diamond.
- Unique brilliance: Its high refractive index (2.42) makes it especially brilliant, reflecting light with great intensity.
- Rarity: Although diamonds are more common than one might think, gem-quality diamonds (clear, large, and free of impurities) are extremely rare.
- Composition: It is made exclusively of carbon, although small traces of other elements can alter its color.
History and symbolism of the diamond
The name “diamond” comes from the Greek “adamas,” meaning “invincible” or “unbreakable.” Since ancient times, it has been a symbol of wealth, power, and eternal love. Its use in engagement rings became popular in the 15th century and remains a widely accepted tradition.
What is a brilliant?
A brilliant is not a different stone from a diamond; it is the name given to the most popular and appreciated cut that a diamond can have. This cut was designed to maximize the diamond’s ability to reflect light and produce exceptional brilliance.
Origin of the brilliant cut
The modern brilliant cut has its origins in the 17th century when cutters began experimenting with cuts that optimized the play of light within the diamond. In 1919, Marcel Tolkowsky, a Belgian mathematician, developed a theoretical model that perfected the brilliant cut, establishing ideal proportions to maximize brilliance.
Technical characteristics of the brilliant cut
- Round shape: Its circular design is the most sought after in jewelry.
- Number of facets: It generally has 57 or 58 facets (including the culet, the base of the diamond).
- Facet distribution: Includes 33 in the crown (upper part) and 24 in the pavilion (lower part).
- Superior brilliance: The brilliant cut is famous for its ability to reflect almost all the light entering the diamond, creating a “sparkling” effect.
Difference between a diamond and a brilliant
The difference lies in the use of the terms:
- Diamond: Precious stone in its natural state or cut in any shape.
- Brilliant: Specific cut of the diamond designed to maximize brilliance.

Advantages of the brilliant cut
- Maximum light reflection: It is the cut that best optimizes the gem’s brilliance and sparkle.

Conclusions on the differences between brilliant and diamond
