The Stone Collection

Where Stone
Meets Soul

Two ancient Indonesian stones — volcanic black lava and verdant green sukabhumi — shaped by nature, specified by the world's finest architects, now exclusively through KAYU for the Indian market.

The Stone Collection

The Beauty of Stone
in Your Space

Stone is the oldest material in architecture — and the most honest. It carries the memory of the earth it came from. At KAYU, we bring you two of Indonesia's most extraordinary natural stones, each with a character that transforms walls, floors, pools and facades into living, breathing surfaces.

I
Bali Black Lava Stone
Volcanic · Porous · Timeless
Born from Fire
Walls That Endure
Formed in high-temperature volcanic conditions, Bali Black Lava Stone is porous, cool to the touch, and endlessly resilient. Its elegant grey-black surface carries the raw beauty of the earth — no two tiles are ever the same.

II
Bali Green Sukabhumi Stone
Zeolite-Enriched · Pool-Grade · Enduring
Nature's Pool Stone
Surfaces That Purify
Green Sukabhumi can only be found in Indonesia. Enriched with natural Zeolite, this stone purifies water, resists temperature, and holds its verdant colour for decades. The world's most iconic resorts specify it — now it's available for your home.

Proof of Concept

Both Stones,
One Facade

The KAYU flagship showroom in Indiranagar, Bangalore uses both Bali Black Lava Stone and Bali Green Sukabhumi for its perimeter wall cladding — a living demonstration for every architect who walks through the door.

Black lava frames the signage. Green sukabhumi accents the borders. Together, they create a facade that is unmistakably KAYU.
