Inspired by three precious stones.
In 1965, Platinum amazed the world by releasing the very first retractable fountain pen. Six decades later, the Japanese brand is celebrating that milestone with a very special limited edition of its CURIDAS model, now reimagined with inspiration drawn from natural gemstones.
After the return of the retractable fountain pen in 2020 under the name CURIDAS—quickly praised for its innovative design—this commemorative series arrives in three exclusive colors. Each shade channels the allure and energy of precious stones, giving the pen an elegant and distinctive character.
The shimmering, iridescent finish of each piece catches the light from different angles, revealing a dynamic play of colors. On the practical side, CURIDAS stays true to its focus on comfort: a nib length optimized for clear visibility on the page, paired with a compact clip that allows a flexible grip. Designed for active writers, it solves one of the most common issues with capped pens—the need to use two hands to open them.
A special sealing mechanism keeps the tip moist and ready to write at any time. And since it’s compatible with a converter, you can enjoy your favorite inks just like with any traditional fountain pen.
Sphene: The Sphene, also known as titanite, has intense colors, strong trichromatism, and a brilliance that surpasses that of diamonds. Although it is softer than many more popular gems, sphene can be a wonderful stone for jewelry if it is set and cared for properly.
A limited-edition retractable fountain pen in shimmering green Sphene. Opens and closes with one hand, always ready to write. Limited to 3,000 pieces worldwide.
