Amethyst (Lab-Created) — the deep violet of amethyst, with consistent clarity.
All the visual character of fine amethyst, grown under controlled conditions to deliver an exceptionally even tone. A graceful, accessible entry into the Precious Stone Collection.
Why this material
- Deep, even violet with high clarity throughout the stone.
- Carries amethyst’s long association with calm, focus, and clarity of mind.
- Hard and lasting — an impression that stays crisp for decades.
A Case as Crafted as the Seal Within.
Made exclusively for us from genuine kimono fabric, each case is patterned with a traditional Japanese motif — animals, flowers, flowing water — a small work of art that honours the seal it holds.
Who it’s for
A thoughtful seal for new chapters — weddings, anniversaries, and those starting a personal practice that is meant to last.

KAMAKURA SIGNET — The Precious Stone Collection
precision-engraved in our Kamakura atelier — a workshop that has practised the art of the seal since 1898, through four generations of the Tsukino family. Each seal is precision-engraved by masters holding Japan’s First-Class National Certification in seal engraving — a distinction shared by fewer than one hundred artisans in the country — in the Tsukino Kissotai script that exists in no other workshop. Among the rarest materials we offer in a personal seal.
A one-of-a-kind work, carved once for a single name. Not a stamp to be used and discarded — an object to be owned, and passed on.
