Norrstone is a premium diamond wholesaler dedicated to delivering exceptional quality, ethical sourcing, and absolute trust. Headquartered in the United Kingdom and rooted in Nordic values of integrity and transparency, we specialize in sourcing and distributing fully certified, high-grade diamonds to discerning clients across the globe.

Our diamonds are meticulously selected and verified by internationally recognized gemological laboratories such as GIA, IGI, and HRD. Each stone is backed by full certification, ensuring its authenticity, quality, and origin.

At Norrstone, we believe luxury should never come at the cost of ethics. That's why we only work with mines, cutters, and suppliers that uphold the highest standards of ethical labor, environmental responsibility, and traceability, in strict alignment with the Kimberley Process and beyond.

Whether serving private collectors, jewelers, or investors, our mission is to make diamond procurement transparent, efficient, and ethically sound — without ever compromising on brilliance.
