Sustainability and Transparency

For a number of years, there’s been growing public awareness relating to the ethical aspects of diamond mining. This has become a priority, directly impacting the way consumers shop and is one of the main criteria when purchasing gemstones. Ethical considerations necessitate full and accurate traceability to ensure the legitimacy in the sourcing and production of all diamonds sold on the market. Each ONEsolitaire diamond is certified and accompanied by detailed quality-related information regarding the number of carats, colour, purity and cut.

How are traceability and sustainability assured?
Our diamonds are sourced via a network of selected reputable dealers from Antwerp, which is the European centre of the diamond trade. Based on the information and certification provided by our suppliers, we ensure that our diamonds are sourced from legitimate sources.
