Industry Trends and Strategic Outlook
The global diamond and jewelry industry is undergoing a transformation driven by evolving consumer preferences, technological advancements, and increasing demand for certification. Rising disposable incomes in India, an expanding middle-class, and the growing appeal of diamonds as a luxury investment continue to fuel market expansion.
A significant trend shaping the global industry is the rapid adoption of Lab-Grown Diamonds (LGDs), which are gaining worldwide acceptance due to their affordability and sustainability. LGD volumes are continuously on the rise, with most large manufacturers of LGDs adding new capacity and wholesale prices stabilizing. As independent certification becomes increasingly essential in ensuring authenticity and quality, IGI’s leadership in this space, positions it at the forefront of this evolving landscape.
Furthermore, the demand for certified diamonds, gemstones, and jewelry is expanding beyond traditional markets, reinforcing the need for transparency and trust in the industry. IGI’s multiple service delivery formats – including IGI Labs, In-factory Labs, and Mobile Labs – enhance customer relationships and provide a distinct advantage in this evolving market. By continuing to embrace innovation and expanding its global footprint, IGI is well-positioned to capitalize on emerging opportunities and reinforce its position as the preferred certification partner for the jewelry industry.
