India’s New Diamond Rule Explained: Why Only Natural Diamonds Can Be Called “Diamonds”

India’s Bureau of Indian Standards (BIS) has introduced a landmark regulatory framework that brings long-awaited clarity to diamond terminology by reserving the term “diamond” exclusively for natural diamonds. This important update strengthens consumer protection and transparency across India’s gem and jewellery industry, particularly in digital and e-commerce platforms where misleading labels have often caused confusion. As an institution dedicated to diamond authentication and jewellery forensics, IIJF Global – International Institute of Jewelry Forensics welcomes this move as a critical step toward informed and ethical diamond purchasing.

Under the new BIS standard, all laboratory-grown diamonds must be clearly disclosed using only the full terms “laboratory-grown diamond” or “laboratory-created diamond.” Shortened forms such as “LGD” or marketing terms like “eco-friendly,” “cultured,” or “pure” are no longer permitted. Even brand names alone are considered insufficient disclosure without the approved qualifier. These guidelines align closely with the principles taught in diamond identification and grading courses at IIJF Global, where professionals are trained to distinguish natural diamonds from lab-grown alternatives using scientific and forensic methods.

The initiative has received strong support from industry leaders and the Natural Diamond Council (NDC), a global not-for-profit organisation operating across India, the US, UAE, Europe, and China. Jewellery experts have emphasized that transparent diamond terminology is essential to preserve consumer trust and protect the long-term value of natural diamonds. With India now adopting a single, enforceable standard, the role of qualified gemologists and jewellery forensic experts, trained through institutions like IIJF Global’s professional certification programs, becomes even more critical in supporting compliance, education, and industry integrity.
