Secret recipe of our Supremacy!

We’re enchanted by the earth’s raw charm and find ourselves basking in the treasure of perfect imperfections every natural stone offers.

Preserving the essence of nature, we toil every step of the way so the quality never diminishes and the authenticity never dies.

Our final goal stays unsmudged i.e. to provide seamless finish and polish to every stone and marble.

The third wheel to our vision and mission, unprecedented technological innovation is the rider between our target and us.

When the best processes meet the best technology a cajoling transformation is bound to take place. We extract and curate designs that last for a  lifetime and keeps the natural charm intact.

The novelty of our textures lie in them being more than about touch and feel of the product. It’s a 4-pillar game of classic thought, modern design, practicality and versatility.

As sturdy as the stone, yet opposite in opacity, the people and processes at
Ninety Degree Stone are as clear and transparent as a crystal.

Stones and marbles make it to home forever, they’re almost its definition. While our designs are contemporary they are quintessentially timeless in elegance and style.

It’s not just about building homes and buildings. It’s more about building trust in you and for your spaces. And that’s how we become a legacy together.
