Why Diamond Matters

For Ortofon, this choice is fundamental.
It is about achieving a level of precision and refinement that defines true high-fidelity sound,
whether in a listening room or behind the DJ booth.

“Diamond is the only material that meets our requirements for precision and refinement.
As the stylus traces the microscopic modulations of the record groove, it requires a material that is both exceptionally hard and capable of being polished to a highly refined geometry.
In this respect, diamond is simply unmatched.”
-Peter Wieth Hjordt, Product Director

The stylus must navigate the record groove with absolute accuracy and maintain consistent contact with even the smallest modulations. Over time, this demands not only precision but also stability.
While alternative materials exist, they do not deliver the same level of performance over time.

“Alternative materials, such as sapphire, can be used, but they do not offer the same level of precision and refinement as diamond. Sapphire styli wear significantly faster, which affects both performance and consistency over time. Diamond, by contrast, maintains its geometry and tracing accuracy far longer, ensuring a more stable and faithful reproduction of the music.”
-Peter Wieth Hjordt, Product Director

This ability to retain its shape and accuracy is essential.
It ensures that performance remains consistent, playback after playback, and preserves both the quality of the sound and the integrity of the listening experience. Ultimately, the choice of diamond is not only about durability or technical performance. It is about staying true to the music itself.

“Ultimately, the choice of using diamond is about preserving the integrity of the music. It enables a more precise reading of the
groove, reduces distortion, and reveals a level of detail that brings listeners closer to the original performance. The result is a sound that is more open, more dynamic, and truer to the artist’s intent.”
-Peter Wieth Hjordt, Product Director

Why Diamond Matters for DJ Applications

For DJs, the demands placed on a stylus are even greater. Techniques such as cueing, back-cueing, and scratching introduce significant mechanical stress and require both precision and robustness under pressure. In these conditions, material choice becomes critical. It influences performance, consistency, and reliability over time.

“For DJs, the stylus operates under particularly demanding conditions. Diamond provides the precision and robustness required to maintain stable tracking, even during cueing and scratching. It ensures consistent performance and helps preserve both the record and the integrity of the sound over time.”
-Peter Wieth Hjordt, Product Director

Diamond’s ability to maintain its geometry, even under these demanding conditions, supports stable tracking and minimizes performance degradation.

This is why every Ortofon cartridge is equipped with a diamond stylus.
It ensures the same standard of precision, durability, and reliability across both HiFi listening and professional DJ use.
