NDC Supports New Indian Standard Aimed at Improving Consumer Clarity on Diamonds

The Natural Diamond Council (NDC) has welcomed the adoption of IS 19469:2025 by the Bureau of Indian Standards, a new framework aimed at bringing greater clarity and consistency to diamond terminology in the Indian gem and jewellery market. The standard is a modified adoption of ISO 18323 and focuses on strengthening consumer confidence through uniform disclosure norms. 

Under the new standard, the term “diamond” used without qualification refers only to natural diamonds. For laboratory-grown diamonds, the standard requires clear and immediate disclosure, permitting only the terms “laboratory-grown diamond” or “laboratory-created diamond” for commercial use. Certain descriptive or promotional terms that could create confusion are not permitted, while “synthetic diamond” may be used in import or export documentation where required by regulation. 

GJEPC, which initiated discussions leading to the development of the standard in coordination with BIS and the Ministry of Consumer Affairs, has said the framework aligns India’s diamond trade with globally recognised guidelines and provides clarity for consumers and the trade 

Commenting on the development, Richa Singh, Managing Director, NDC, said: “Consumer protection is central to everything we do at the Natural Diamond Council. Clear, consistent terminology is essential to maintaining trust. By eliminating ambiguity and mandating full disclosure, these standards protect industry integrity and ensure consumers can confidently distinguish between a natural diamond and a laboratory-grown diamond.” 

NDC said it will continue to work with BIS, trade bodies and industry stakeholders to support awareness and implementation of the new standard, with the objective of improving transparency and consistency across the diamond jewellery sector.
