Read Original ArticleKey Points
Lab-grown diamonds are emerging as a sustainable alternative to natural diamonds amid declining reserves and ethical mining issues. This matters for UPSC aspirants, especially for GS Paper 3, which covers environmental and economic topics. Last Updated: 07-08-2026
Key Facts About Lab-Grown Diamonds
- Definition: Lab-grown diamonds are synthetic diamonds created in laboratory settings, identical to natural diamonds in all properties.
- Objective: To provide an ethical and sustainable alternative to mined diamonds.
- Key Provisions: Manufactured using HPHT and CVD technologies.
- Numbers: India produced over 3 million LGDs in 2023, accounting for more than 15% of global production.
- Outcomes: Reduced environmental impact and ethical sourcing.
- Organizations: India Centre for Lab-Grown Diamond (InCent-LGD), established with a ₹243 crore grant.
India's Push for Indigenous Production
The adoption of lab-grown diamonds aligns with India's strategic goals for sustainable development and economic growth. As the world's leading diamond polishing hub, India is advancing its position in the global LGD market. The country processed around 90% of the world's diamonds and contributed nearly 75% of global diamond trade by value. With the establishment of InCent-LGD, India is poised to become a global leader in sustainable diamond manufacturing.

- GS Paper 2: International Relations - India's role in the Kimberley Process.
- GS Paper 3: Environment and Sustainable Development - Impact of LGDs on reducing ecological damage.
- Prelims Angle: Questions on the definition, production methods, and ethical aspects of LGDs.
- Mains Angle: Analytical themes on sustainable alternatives and India's economic strategies.
FAQ Section
- What are Lab-Grown Diamonds (LGDs)? Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds and are produced using HPHT or CVD technologies.
- Why are Lab-Grown Diamonds considered a sustainable alternative to natural diamonds? They reduce environmental degradation, eliminate concerns over conflict diamonds, ensure traceable sourcing, and have a lower carbon footprint when produced using renewable energy.
- What initiatives has India taken to promote Lab-Grown Diamonds? The Union Budget 2023-24 promoted indigenous LGD production, while IIT Madras established the India Centre for Lab-Grown Diamond (InCent-LGD) with a ₹243 crore grant to advance HPHT and CVD technologies.
- What is the Kimberley Process? The Kimberley Process Certification Scheme (KPCS) is an international initiative that certifies rough diamonds as conflict-free to curb the trade in blood diamonds, although regulatory loopholes still exist.
