BIS Sets New Diamond Rules: Only Natural Diamonds Can Be Called 'Diamond' Unqualified

• The Bureau of Indian Standards (BIS) has implemented new rules (IS 19469:2025) for diamonds to protect consumers and increase transparency.
• The new standard aims to eliminate confusion caused by misleading terms for diamonds and their alternatives, especially on online platforms.
• Under the new rules, the term "diamond" without a qualifier will exclusively refer to natural diamonds; terms like "natural," "real," "genuine," or "precious" can be used with it.
• Lab-grown diamonds must be explicitly labeled as "Laboratory Grown Diamond" or "Laboratory Created Diamond," with abbreviations like "LGD" no longer permitted in formal disclosures.
• Misleading terms such as "Nature," "Pure," "Earth Friendly," or "Cultured" are prohibited for lab-grown diamonds to ensure clear and honest information for consumers.

Why It Matters: BIS new rules clarify diamond terminology, ensuring only natural diamonds are called 'diamond' unqualified, boosting consumer trust.
