Key themes

LGD volume surge and AGL integration

How the narrative shifted

• LGD volume and capacity up cycle: LGD demand remains healthy; incremental grower capacity coming online widens the addressable market for independent certification, positioning IGI to capture volume growth.
• Natural diamond market share capture: Natural diamonds are a strategic priority; IGI is winning new customers and growing share of wallet, with LGD consumers upgrading to natural and already trusting the IGI brand.
• Coloured stone expansion via AGL: AGL acquisition brings coloured stone expertise and expands TAM; IGI will globalize AGL, starting with Jaipur, creating a new growth avenue beyond diamonds.
• One IGI retail-engagement model: The combined strength of India’s certification capacity and foreign subsidiaries’ retail outreach generates commission payouts but expands group margins, reinforcing the integrated model.
• Brand building and consumer marketing: Previously B2B-focused, IGI is investing in consumer-facing brand (IPL sponsorship, etc.) to build trust and recognition, with spends front-loaded and expected to moderate.
• AI and operational efficiency: AI/ML is being deployed to shorten turnaround times and improve service quality, with data being fed into models to optimize workforce utilization.
• Consumer trend: LGD acceptance and upgrade to natural: LGD affordability brings new consumers into diamonds, who then upgrade to natural stones; both segments benefit from IGI certification, reinforcing demand.

Operational commentary

• AGL consolidation begun contributing to revenue, expanding into coloured stone gemstones; plans to launch AGL operations in Jaipur and take the brand global.
• LGD grower capacity expected to double over next three years, driving sustained volume growth for IGI; India remains hub for 95% of diamond cutting/polishing.
• Strengthened leadership with appointment of COO Manu Sharma (ex-Reliance Brands) to drive brand management and business growth.
• Deployment of AI/ML models to reduce turnaround time and improve operational efficiency, feeding all certification data into machine learning.
• Commenced operations in Italy through Belgium subsidiary; US and other international subsidiaries gaining traction, driving consolidated growth.
• Invested ~₹5 Cr in IPL sponsorship (Gujarat Titans) and other consumer-facing marketing to build IGI brand awareness beyond B2B channels.
• India standalone margins temporarily lower due to commission payouts to foreign subsidiaries for retail leads, reflecting 'One IGI' model; group EBITDA margin expanded 270 bps YoY.

Analyst Q&A

• Q. Given LGD production capacity expansion, is there pricing pressure on per-report realizations?

  Certification is central to making LGD a diamond; price determines market expansion but IGI's role is to provide consumer confidence. The underlying wholesale price per carat has remained stable in the 80-120 range for two years.

• Q. What is the medium- to long-term thought process for AGL and its geographical expansion?

  AGL is a strategic move into coloured gemstones. AGL gets IGI’s global platform; they will start in Jaipur with collection windows and mobile labs, then expand to other regions where relevant. The intention is to take AGL’s coloured stone expertise globally.

• Q. Is there potential for further acceleration in ND loose certification growth in international markets?

  Yes, ND market share gains are a strategic priority. LGD is creating a new consumer base that upgrades to natural diamonds; these consumers are already exposed to IGI certification, benefiting ND loose growth.

• Q. How do you see the blended realization per report evolving, and what is the full-year expectation?

  Underlying pricing has been stable since the April-May 2024 correction. The 5% ASP improvement this quarter includes 3% from AGL and 2% from mix (higher caratage in LGD). Realization will depend on mix shifts (e.g., jewelry volume), but overall pricing is stable.
