Special collections - Hidden diamond.

Why Want More.

Mastery is hidden in detail. You can expect it from the collection that combines the know-how collected over four centuries, the finest materials and craftsmanship.

Just as the KOH-I-NOOR diamond, which is part of the British Crown Jewels, has become a standard of excellence and inspired the emergence of the KOH-I-NOOR HARDTMUTH brand, today we aim to show the world the selected jewels from our production through the Hidden Diamond product range.

Don't save extraordinary equipment for more festive occasions. Turn your everyday life into precious moments, because life itself is the most precious thing that could have happened to us.

KOH-I-NOOR HARDTMUTH TIP: Your table will be beautifully decorated with a luxurious Retro Polycolor box, whose retro design is based on a successful collection made in the early 20th century.
