    The Challenge

    GemHub needed a trusted marketplace for high-value gemstones where buyers and sellers could transact with confidence and verify authenticity. The luxury gemstone market faces unique challenges that traditional ecommerce platforms cannot address.

    Key Challenges

    • Building trust for $10K-$500K transactions between strangers
    • Verifying gemstone authenticity and certification from multiple labs
    • Protecting both buyers and sellers in high-value disputes
    • Providing visual confidence through professional product imagery

    Our Solution

    We built a secure marketplace with certification verification (GIA, AGS), escrow payments, and stunning product visualization. The platform builds trust through transparency, buyer protection, and rigorous seller verification.

    Certification Verification

    Every gemstone listing connects to major certification labs including GIA, AGS, and IGI. Buyers can verify certificate authenticity directly through the platform, eliminating counterfeit concerns and building immediate trust.

    360° Product Visualization

    Our custom Three.js viewer allows buyers to examine gemstones from every angle with professional-grade macro photography. The interactive experience replicates the in-person examination process that luxury buyers expect.

    Secure Escrow System

    High-value transactions are protected through our Stripe Connect-powered escrow system. Funds are held securely until buyers confirm receipt and authenticity, with built-in dispute resolution and insurance coverage.
