Arumin offers a selection of high-quality Ceylon sapphires, sourced in accordance with strict ethical standards and backed by full traceability.
Our Purpose
Changing the way Ceylon sapphires are valued. At their origin, for their people.
The Ceylon sapphire trade has long prized rarity, but often overlooked the importance of origin, and the people and places behind each stone. Arumin was created to change that.
In Sri Lanka, sapphires are more than a natural resource. They are part of the island’s cultural and historical identity. Known as Ratnadeepa, the Island of Gems, Sri Lanka has quietly supplied the world with stones of remarkable quality. Yet the long-term rewards of this trade have rarely remained with those closest to it.
We believe there is a better way. Arumin is founded on the idea that rarity must be matched by responsibility. We are committed to sustainable sourcing, fair practices, and a model that strengthens the lives and economies connected to each stone.
Each Arumin sapphire is selected at source and cut to the highest standards. It carries not only rarity, but also purpose, provenance, and the spirit of its origin.

Collaboration for Progress
Arumin works in close partnership with local stakeholders in Sri Lanka to strengthen the sapphire trade and ensure that more of its true value remains within the country.
Our efforts focus on setting higher standards, promoting ethical sourcing, and building lasting global recognition for Sri Lanka’s gem heritage, helping the industry create lasting benefits for local communities and the nation as a whole.
