GSI Open Gem Lab in Indore: In a strategic move that promises to revolutionise gemstone and jewellery certification in central India, Gemological Science International (GSI) inaugurated its new satellite laboratory in Indore, Madhya Pradesh, on January 24, 2025. This development marks a significant milestone for the region’s burgeoning jewellery industry, bringing world-class certification services directly to local jewellers and consumers.
For decades, jewellers in Madhya Pradesh relied heavily on sending their inventory to Mumbai, Surat, or Jaipur for certification—a process that was time-consuming and logistically challenging. The new GSI facility changes this equation entirely, offering same-day certification services that empower local businesses to serve their customers more efficiently while maintaining the highest standards of quality assurance.
This comprehensive guide explores everything you need to know about GSI’s Indore laboratory, its services, technology, and how it’s positioned to support the rapidly growing jewellery market in Madhya Pradesh.

Why GSI Chose Indore: Market Dynamics and Opportunity
The Shifting Landscape of Madhya Pradesh’s Jewelry Industry
The rise in customer demand for customized jewelry has spurred a shift toward local manufacturing in Madhya Pradesh, reducing reliance on sourcing from Mumbai, Surat, and Jaipur, according to GSI India Managing Director Ramit Kapur.
Growing Market Demand
Several factors contributed to GSI’s decision to establish a presence in Indore:
1. Local Manufacturing Growth
Madhya Pradesh has witnessed steady growth in jewelry manufacturing and trading operations. As consumers increasingly demand customized and personalized pieces, local artisans and manufacturers are stepping up to meet this need.
2. Certification Gap
While the state has always had a vibrant jewelry market, the lack of local certification services created significant operational challenges for jewelers. Sending pieces to Mumbai or Jaipur meant:
- Longer turnaround times (often 7-14 days)
- Higher logistics costs
- Risk during transportation
- Inability to provide immediate certification to walk-in customers
3. Consumer Awareness
Today’s jewelry buyers are more informed and demand transparency. They want certified pieces that guarantee authenticity, quality, and value—making local certification services essential.
India’s Booming Jewelry Market
The broader context makes GSI’s expansion even more strategic:
- India’s gems and jewelry market is projected to reach $130-140 billion by 2029
- The organized retail sector’s share is expected to grow from 37% in 2024 to 43-47% by 2029
- Branded jewelry now accounts for approximately 35% of the market
- Online jewelry sales are growing at over 8% annually

- Investment-grade pieces may lack proper documentation
Insurance and Resale Value

Bulk submissions often receive discounted rates. Contact the Indore laboratory directly for current pricing and any promotional offers for first-time customers or bulk submissions.
Can I get antique or heritage jewelry certified at GSI Indore, and what special considerations apply?
Yes, GSI Indore specializes in certifying antique and heritage jewelry, including traditional polki pieces. For heritage items, the laboratory takes extra precautions including non-invasive testing methods to preserve the integrity of the piece. The certification process includes documentation of craftsmanship, metal purity testing, and authentication of stones within their settings. For antique pieces, GSI can provide historical context where possible and identify period-specific characteristics. It’s recommended to bring any existing documentation, provenance information, or previous appraisals to support the certification process. The laboratory’s expertise in polki jewelry makes it particularly well-suited for traditional Indian heritage pieces.
How can I verify the authenticity of a GSI certificate I’ve received or am considering purchasing?
GSI certificates can be verified through multiple methods. The easiest is scanning the QR code printed on the certificate using your smartphone, which directs you to GSI’s verification portal showing the complete digital report. Alternatively, visit GSI’s official website and enter the unique report number in the verification section. Physical security features include holographic elements, special watermarked paper, UV-reactive elements, and microprinting that are difficult to replicate. If purchasing jewelry with a GSI certificate, always verify the certificate authenticity before completing the transaction. Be wary of certificates without QR codes or those that cannot be verified online, as these may be fraudulent.
What’s the difference between getting my jewelry certified at GSI versus having it appraised by a local jeweler?
Certification and appraisal serve different purposes. GSI certification provides an objective, independent laboratory analysis of the physical and optical characteristics of diamonds and gemstones—their identity, quality, and any treatments. It does not assign monetary value. A local jeweler’s appraisal typically provides an estimated market value for insurance or resale purposes, but may lack the independent verification and detailed gemological analysis that laboratory certification provides. For complete protection, many people obtain both: GSI certification to document the quality and authenticity of the stones, and a separate appraisal for insurance value. The GSI certificate can actually support higher appraisal values by providing independent verification of quality.
Does GSI Indore offer educational programs or workshops for jewelry professionals and enthusiasts?
Yes, GSI Indore provides educational workshops and training programs designed for retail sales teams, jewelry professionals, and serious enthusiasts. These workshops cover topics including understanding diamond and gemstone quality factors, interpreting certification reports, advanced sales strategies, identifying common simulants and treatments, and effective customer communication about certification. Programs range from half-day workshops to more comprehensive multi-day courses. Jewelry retailers can arrange private training sessions for their staff. Individual enthusiasts can inquire about scheduled public workshops. Contact the Indore laboratory directly for current educational offerings, schedules, and registration information. These programs are valuable for anyone wanting to deepen their gemological knowledge or improve their professional skills in the jewelry industry.
