Best Practice Principles

Ethical business conduct, anti-corruption, transparency and compliance across the diamond pipeline. The Best Practice Principles ensure that every stage of a diamond's journey meets the highest professional and ethical standards.

Community upliftment, fair labour practices, education, health and welfare programmes in sourcing regions. CrownStone Diamonds invests in projects that reach people across the countries where diamond recovery takes place.

Environmental stewardship, conservation, sustainable practices and minimising the impact of diamond recovery. The Best Practice Principles help prevent unacceptable environmental practices across the diamond pipeline.

Responsible extraction, safe working conditions, Kimberley Process compliance and OECD due diligence. Every stage of the movement of diamonds must be assessed for potential risks under the Best Practice Principles.
