Where Global Certification Meets Thai Craftsmanship

Authenticity is everything when purchasing precious stones. At WBGEM, we operate as a Gübelin, SSEF, GRS, GIA, IGI, and AGS certified gemstone shop in Thailand, serving clients across the USA and Europe.

Each gemstone in our collection is examined and verified by world-renowned laboratories ensuring proven authenticity, natural origin, and accurate value assessment. Whether you’re a collector, jeweler, or investor, WBGEM guarantees certified gemstones with appreciation potential and complete transparency.

Why Certification Matters When Buying Gemstones

Certified gemstones command higher trust, liquidity, and long-term value. Each report acts as a passport for your gem, verifying:

Natural or treated status
Country of origin
Gem species and variety
Measurements, weight, and clarity
Laboratory-issued identification numbers
Buying uncertified gemstones exposes the buyer to uncertainty, while laboratory-certified stones safeguard authenticity and investment confidence.

Each gem within WBGEM’s collection is certified by one or more of these globally respected labs:
