Why Jewellers Choose Orange River

With direct experience in gemstone sourcing, cutting and trade distribution, Orange River understands the practical realities of working with natural stones in a retail and manufacturing environment.

We prioritise:

• Clear disclosure of treatments and origin where known
• Reliable grading, accurate measurements and honest colour representation
• Consistent supply relationships and trade-focused service
• Ethical and responsible sourcing practices

In addition to dependable wholesale supply, Orange River offers short-term approval (memo) options for eligible jewellery professionals. This allows jewellers to present loose gemstones and diamonds directly to retail clients, facilitating informed decision-making and helping close sales with confidence.

Our memo service is designed to support real-world retail workflows, enabling jewellers to secure client commitment before final manufacture, reduce stock risk, and provide a higher-quality purchasing experience.

Orange River’s role is not simply to supply gemstones, but to act as a trusted trade partner, supporting jewellers with stones they can confidently present, sell and stand behind.
