India Makes "Diamond" Mean Natural Diamond Only

Shopping for a diamond in India used to mean wading through confusing terms, vague descriptions, and inconsistent labels that left buyers guessing what they were actually purchasing. That changes now.

India's Bureau of Indian Standards just adopted a new rule that draws a clear line in the sand. From now on, the word "diamond" standing alone means one thing only: a natural diamond formed deep in the earth.

The new standard, IS 19469:2025, brings order to a market where digital platforms and jewelry stores had been using dozens of different terms to describe both natural and laboratory-grown diamonds. Consumers often couldn't tell what they were buying, especially online where shortcuts and abbreviations ruled.

Under the new framework, sellers can describe natural diamonds as "diamond," "natural diamond," "real diamond," "genuine diamond," or "precious diamond." All of those are fine because they're clear.

Laboratory-grown alternatives must now be called exactly that: "laboratory-grown diamond" or "laboratory-created diamond" in full, every time. No more shortcuts like "LGD," "lab-grown," or "lab-diamond" in official disclosures.

The rules also ban misleading language. Sellers can't describe lab-grown diamonds as "nature's," "pure," "earth-friendly," or "cultured." Using just a brand name without the full "laboratory-grown" qualifier doesn't cut it either.

The Ripple Effect

This clarity matters beyond individual purchases. India is one of the world's largest diamond markets, and the jewelry trade there employs millions of people from cutters to retailers.

Jewelers across the country have welcomed the change. Retailers say transparent terminology strengthens the foundation of trust their entire industry depends on, especially in a market where diamond purchases often mark life's biggest moments.

The standard helps preserve both the emotional and financial value of what people are buying. When someone saves for an engagement ring or celebrates a milestone with diamond earrings, they deserve to know exactly what they're getting without decoding abbreviations or second-guessing sales language.

The Natural Diamond Council, which supported the adoption, says the move protects informed choice. With clear definitions in place, consumers can make decisions based on what matters to them, whether that's origin, price, or personal values.

India's framework follows international standards, adapting ISO guidelines to local market needs. It puts consumer protection front and center in an industry that had been operating without formal terminology rules.

One simple word now carries one clear meaning, and that clarity protects everyone.
