收藏: Rough & Uncut Gemstones
Directly sourced, naturally authentic
The majority of our rough gemstones are sourced directly, or just one supply chain away, from nearby mines in Thailand, Laos, and Cambodia. We also occasionally offer carefully selected pieces from other gem regions, including Africa. By collaborating exclusively with long-term, verified partners, we ensure authenticity, ethical standards, and exceptional quality.
Short supply chains, lasting value
Our approach reduces supply chain length, supports sustainability, and allows us to offer competitive prices per gram. Each stone is unique, carrying within it the raw beauty of its origin – and sometimes, treasures whose value may surpass expectations.
