We are deeply committed to responsible sourcing and maintains the highest standards of transparency and quality in its operations. Every diamond we handle is meticulously traced, ensuring its journey is fully documented from its origin to its final form.
Sourced through verified channels and produced within a traceable manufacturing framework, our natural mined diamonds reflect precision, transparency, and controlled standards at every stage.
We strictly adhere to the Kimberley Process Certification Scheme (KPCS), guaranteeing that every mined diamond we purchase is conflict-free. This unwavering dedication reflects our commitment to ethical practices and delivering only the finest, responsibly sourced diamonds to our customers.
We create positive environmental impact by using ethically sourced diamonds, 75% recycled metals, and renewable energy in every piece we craft. Our shorter supply chain results in a far smaller environmental footprint compared to other earth-mined diamonds.
Our lab-grown diamonds are cultivated using advanced technological processes within controlled environments. Each stone reflects innovation, precision, and modern manufacturing standards.
Responsibly produced using advanced tech in controlled environments, our lab-grown diamonds reduce reliance on traditional mining practices. Engineered for traceability and resource efficiency, they offer a transparent alternative aligned with evolving sustainability expectations.
Our commitment to sustainability extends beyond sourcing. Every stage of our lab-grown diamond production — from advanced technology to manufacturing and polishing — is powered by renewable energy, reducing fossil fuel dependence and lowering our carbon footprint.
As part of our dedication to environmental responsibility, we have set an ambitious goal to achieve carbon neutrality in all of our manufacturing activities by 2026. Through innovative solutions, energy-efficient practices, and strategic partnerships, we are actively working to minimize our environmental impact and contribute to a cleaner, greener planet for future generations.
Jewelstar Group takes a holistic approach to environmental responsibility, and these efforts reflect a disciplined commitment to environmental care that parallels operational excellence.
Jewelstar Group monitors and manages its environmental impact through a comprehensive Greenhouse Gas (GHG) Inventory & Carbon Offset Report, aligned with PAS 2050 and ISO 14067 standards.
Fuel combustion and refrigerant leakage account for 8.03 tCO₂e, representing 2.98% of total emissions, measured across diesel, natural gas, and refrigerant use.
Indirect emissions total 261.5 tCO₂e, driven primarily by purchased electricity, which constitutes 97.02% of overall emissions during the reporting period.
At 3.209 kg CO₂e per carat of polished lab-grown diamond, we focuses on lowering emissions per unit through energy efficiency, cleaner power adoption, and verified offset.
Sustainability at Jewelstar is embedded into how each diamond is grown, processed, and finished. By measuring impact at the base level and refining process efficiency, we ensure consistent lighter footprint.
Each CVD diamond is evaluated across its full production lifecycle—from growth and processing to polishing—capturing energy use, material inputs, and operational emissions.
With a verified footprint of 3.209 kg CO₂e per carat of polished LGD, we maintains one of the industry’s lowest emission intensities through optimized and efficient resource use.
Advanced CVD and HPHT systems, energy monitoring, and waste-reduction practices continuously refine efficiency, lowering environmental impact without compromising quality.
Water security is fundamental to livelihoods and dignity. The Group invests in long-term infrastructure, creating access that supports agriculture, communities, and future generations.
Jewelstar funded the construction of the Kalubhar Dam, Gujarat, designed to store water year-round, providing permanent irrigation and local access amidst unreliable supply.
The project now supports over 50,000 farmers across villages such as Chamaradi and Ratanpur, stabilising crop cycles, improving yields, and strengthening rural economic resilience.
Reliable water access has enabled education, local enterprise, and community collaboration, all while reducing hardship and creating conditions for long-term social development.
Every mined diamond we handle is sourced with responsibility, verified provenance, and respect for people and place—because trust begins long before a stone is cut.
All mined diamonds are sourced in full adherence to the Kimberley Process Certification Scheme, ensuring conflict-free origin through internationally enforced standards.
Each diamond is digitally tracked through integrated ERP and CRM systems, providing complete visibility, documented provenance, and accountable supply-chain control.
We prioritise ethical labour practices, safeguards, and long-term sustainability supporting a diamond trade that protects communities while preserving confidence in natural diamonds.
Jewelstar’s innovation framework integrates advanced manufacturing, lab-grown science, and digital intelligence to deliver precision, scalability, and future-ready jewelry solutions.
Large-scale tree planting supports carbon sequestration, improves air quality, stabilises soil, and restores natural ecosystems through carefully selected native species.
Working alongside local communities, NGOs, and government bodies, our plantations are designed for longevity—maintained, monitored, and grown to maturity for lasting impact.
Plantation is part of a wider framework that includes responsible resource use, waste reduction, and energy efficiency, reducing our ecological footprint at scale.
At Jewelstar Group, certifications are more than just accolades—they’re a testament to our unwavering commitment to sustainability, ethical practices, and creating a positive impact. Our production units adhere to the highest global standards, ensuring excellence across every step of the process.
