Aji Project Aji Stone OT- Vase Sabo

AJI STONE · TAKAMATSU, KAGAWA

A Rare Japanese Granite Quarried Only in Takamatsu, Kagawa

Aji Stone is a rare and highly esteemed granite found exclusively in the northeastern region of Takamatsu City, Kagawa Prefecture, Japan. Known for its exceptional density and refined grain, this stone is prized for both its durability and natural beauty.

With a Mohs hardness rating of 7 — comparable to quartz — Aji Stone surpasses most decorative stones in strength (for comparison, marble ranks at 4). Its tightly bonded fine particles enable precise and delicate craftsmanship. Moreover, its low moisture absorption makes it highly resistant to weathering, ensuring long-lasting quality.

Hand-Finished by Stone Artisans in Kagawa

Due to the stone's remarkable hardness and density, working with Aji Stone requires a high level of expertise. In its place of origin, specialized artisans handle each stage of the process — from quarrying and cutting to polishing, engraving, and shaping. Their generational craftsmanship brings out the full character of the stone, transforming it into a piece of functional art.

A Cactus-Inspired Granite Vase with Sculptural Ridges

This granite vase takes its character from vertical ridges carved into the surface of Aji Stone, giving it a form reminiscent of a cactus. Available in three different heights, each piece has a compact, sculptural presence that works with a single flower or simply as an object on its own. Displayed individually or grouped together, the different proportions create a subtle rhythm within the space.
