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.
