Amber (Square) — fossilised resin, in a calligrapher’s square form.
Warm, translucent amber set into a square seal — the form traditionally favoured by calligraphers and painters to mark their work.
Why this material
- Genuine amber with natural translucency and honeyed warmth.
- Each piece carries unique inclusions — no two seals alike.
- The square form sits firmly between the fingers, present and deliberate.
Who it’s for
For calligraphers, painters, and collectors — and a striking gift for those starting a personal creative practice.

KAMAKURA SIGNET — The Masterpiece Collection
Rare, time-honoured natural materials, hand-finished to last for generations. Every seal is finished by hand in our Kamakura atelier — practising the craft since 1898, across four generations of the Tsukino family — by masters holding Japan’s First-Class National Certification, in the Tsukino Kissotai script found in no other workshop.
hand-finished to endure, and to be handed down — a personal mark made to outlast the page it is pressed upon.
