What’s Changed in the New Standards
Under the newly notified IS 19469:2025 standard, adapted from ISO 18323:2015, the word “diamond” can now be used only for natural diamonds. Any lab-grown stone must be clearly disclosed using approved terms such as “laboratory-grown diamond” or “laboratory-created diamond.”
The standards also ban misleading or outdated descriptors like fake, artificial, synthetic, or cultured. Even commonly used short forms such as lab-grown, lab-created, lab diamond, or LGD are no longer permitted on labels or certificates.
Full Transparency on Production Methods
BIS now requires complete disclosure of production techniques, including Chemical Vapour Deposition (CVD) and High Pressure High Temperature (HPHT). Any treatments or post-growth enhancements must also be clearly stated, ensuring transparency from origin to final product.
A Comprehensive Disclosure Framework
Developed by the BIS MTD 10 Committee, following an initiative by the Gem and Jewellery Export Promotion Council (GJEPC) and consultations with the Ministry of Consumer Affairs, the revised framework standardizes terminology and disclosure for:
Natural diamonds
Laboratory-grown diamonds
Treated diamonds
Composite stones
Diamond imitations
Industry Impact
An industry expert compared the move to hallmarking, noting that the new standards will remove long-standing confusion caused by inconsistent certifications. Kirit Bhansali, Chairman of GJEPC, highlighted that these norms enhance credibility across both natural and lab-grown segments and reinforce India’s leadership in ethical diamond trade practices.
Market Context
India’s jewelry market, valued at nearly $80 billion in FY24, is projected to grow to $225 billion by FY35, supported by strong domestic demand. India is now the world’s second-largest diamond jewelry market, with current demand around $10 billion, expected to double by 2030. Similar labeling norms already exist in developed markets, making this step essential for India’s global competitiveness.
Why This Matters
Removes ambiguity between natural and lab-grown diamonds
Protects consumers from misleading claims
Aligns India with international standards
Strengthens trust in India’s fast-growing jewelry sector
What It Means for Industry Professionals
For gems and jewelry professionals, the BIS norms are both a responsibility and an opportunity. Businesses that adopt transparent labeling and compliance practices early will gain a clear edge as consumer awareness grows.
Key Takeaways
Stay compliant: Understand and implement IS 19469:2025 standards
Build trust: Transparency is now the backbone of sustainable growth
Career opportunity: Expertise in compliance and ethical practices will be in high demand
Industry readiness: Knowing the difference between natural and lab-grown diamonds is now essential
These standards are more than regulatory changes. They serve as a roadmap for building credibility, protecting consumers, and shaping a responsible future for India’s diamond industry.
