BIS reserves 'diamond' for natural stones, forces lab-grown disclosure across India retail
New BIS disclosure norms restrict the term 'diamond' to natural stones and mandate explicit labeling of lab-grown variants. Jewellers including NAC and Ranka are overhauling labels, catalogues and certification to comply, reshaping how India's diamond retail communicates value at the counter.
BIS has introduced disclosure norms for India's diamond retail industry, reserving the term 'diamond' for natural stones and mandating explicit labeling of lab-grown variants. Retailers are revising labels, catalogues and certification practices to align with the new transparency standards.
Why this matters
BIS continues expanding authenticity enforcement, following its DNA testing pilot for buffalo meat exports. The diamond ruling extends standards-led consumer protection from food integrity into high-value retail jewellery categories.
Retail-brand signals steady at 567 over 90 days, reflecting consistent brand-compliance activity.
