Our focus lies in establishing strong, trusted relationships with miners, suppliers, and tender houses to ensure a consistent and reliable supply of responsibly sourced rough diamonds. Every stone we trade is handled in full compliance with the Kimberley Process regulation, reflecting our dedication to integrity, transparency, and accountability. Through these principles, OYL Rough Stones upholds the highest ethical and professional standards across every aspect of its operations.

The OYL Rough Stones management team comprises of skilled professionals with extensive experience in diamond grading, valuation, and trade logistics. Our founder and Director, Omri Yedid Levi, brings a wealth of hands-on expertise, having spent many years as a rough diamond evaluator specialising in marking, cutting, and polishing before establishing the BYL Diamond Group. Under his leadership, the team combines decades of collective knowledge and practical industry experience, enabling OYL Rough Stones to navigate the complexities of the diamond market while maintaining the highest standards of quality and service.

As OYL Rough Stones continues to expand, our vision is to become a recognised and respected leader in the rough diamond trade, synonymous with excellence, integrity, and innovation in every aspect of our business.

We aim to strengthen our presence across global markets, deepen our relationships within the diamond supply chain, and continuously elevate the standards of quality and service that define our brand.
