Diamonds, renowned for their exceptional hardness and brilliance, have captivated humanity for centuries. However, with the rise in synthetic diamonds and diamond simulants, the need for accurate and efficient testing methods has become paramount. One of the oldest and simplest methods employed by gemologists is the use of a scratch pen, more commonly known as a corundum pen.
Understanding the Corundum Pen Test
A corundum pen is essentially a stylus made of corundum, a mineral with a hardness of 9 on the Mohs scale. Diamonds, with a hardness of 10, are the only naturally occurring substance harder than corundum. By gently scratching the stone with the corundum pen, a skilled gemologist can determine whether the stone is likely a diamond or a different material.

- Diamond: Will not be scratched by the corundum pen.
- Simulant: Will likely be scratched, leaving a visible mark.
It’s important to note that while the corundum pen test provides a quick and preliminary assessment, it should not be relied upon as the sole method of diamond identification. Other testing methods, such as those involving specialized equipment, are necessary for definitive results.
The Importance of Gemological Expertise
Properly using a corundum pen requires a keen eye and extensive knowledge of gemstones. Misinterpretation of results can lead to incorrect identification. To ensure accurate diamond testing and grading, it is essential to seek the services of a qualified gemologist.
