Since 1945 quality, reliability and product performance have been a precise goal for the Longoni family to reach out to its customers all over the world.
A buyer needs the certainty of authenticity to live a rewarding experience of use especially when it comes to sports and performance.
Authenticity also means investment security and certainty of the quality of the materials, those chosen by Longoni for its products.
In 2019 the Longoni brand started a partnership with Certilogo, a leading Italian company in the sectors of authenticity and consumer engagement.
This company, based in Milan, has offices all over the world and assists numerous leading brands of made in Italy, in luxury and fashion.
The famous Blue Diamond billiard chalk was chosen by Longoni as the first product to use the brand protection solution developed by Certilogo®, applying an univocal identification code on each single package of 2 cubes.
BLUE DIAMOND CHALK
An icon in the world of billiards for over 70 years.
Blue Diamond is far more than just a cue chalk. It is one of the most iconic products in billiards history and a true symbol of the Longoni tradition.
Originally created in France in the years following World War II, Blue Diamond later became part of the Longoni family, which has preserved its heritage while continuously refining its manufacturing process. Today, it is produced in the United States using an exclusive formula and carefully aged in Italy to ensure the consistency, quality, and performance that have made it a worldwide benchmark.
Its distinctive smooth yet compact texture provides excellent adhesion to the cue tip, delivering a consistent chalk coating and reliable grip.
The result is enhanced cue ball control, greater confidence when applying spin, and the unmistakable playing feel that has earned the trust of players at every level—from passionate amateurs to world-class professionals—for more than seven decades. In an ever-evolving market, Blue Diamond continues to stand out thanks to its perfect balance of tradition and performance.
It is the ideal choice for players who appreciate the authentic feel of a classic chalk while demanding the consistency expected in modern billiards. Its exceptional value for money remains one of its greatest strengths. A box containing two cubes delivers hundreds of hours of dependable play, making Blue Diamond one of the best long-term investments for any player. Every cube is individually inspected to meet Longoni’s rigorous quality standards. True icons are often imitated. That is why every genuine Blue Diamond package is protected by the Certilogo® authentication system, allowing players to verify its authenticity online, and is presented in the new official Longoni packaging. Over 70 years of heritage.
Millions of games played.
One legendary name: Blue Diamond.
