How to Verify a Jeweler's Reputation in Thailand
Thailand is a world-renowned jewelry destination, but that reputation also attracts scammers. Here's how to identify trustworthy jewelers and shop with confidence.
Know the Signs
Green Flags
- Member of Thai Gem and Jewelry Traders Association (TGJTA)
- Provides GIA, IGI, or HRD certificates for diamonds
- Clear return and exchange policy in writing
- Physical store with established history (5+ years)
- Positive reviews on Google, Facebook, and Wongnai
- Willing to show diamonds under loupe/microscope
- Transparent about pricing and diamond specifications
- Offers proper receipts and documentation
Red Flags
- Pressure tactics or 'today only' deals
- No certification or 'in-house' certificates only
- Refuses to let you inspect stones closely
- Unusually low prices (too good to be true)
- Located primarily in tourist-heavy areas
- No physical store or meets only in hotels/airports
- Vague about return policies
- Cash-only transactions
5-Step Verification Process
Check Association Membership
Verify membership in TGJTA (Thai Gem and Jewelry Traders Association) or GIT (Gem and Jewelry Institute of Thailand). Members must follow ethical standards.
Visit verification site →Research Online Reviews
Check Google Maps, Facebook, Wongnai (Thai Yelp), and TripAdvisor. Look for consistent positive feedback over multiple years, not just recent reviews.
Verify Diamond Certificates
GIA certificates can be verified at gia.edu/report-check. IGI certificates at igiworldwide.com. Never trust unverifiable 'in-house' certificates.
Visit the Physical Store
Established jewelers have proper storefronts. Be cautious of sellers who only meet in hotels, airports, or tourist areas.
Ask for Documentation
Request a detailed invoice with diamond specifications, metal type, and all pricing. This protects you and is required for insurance.
Common Thailand Jewelry Scams
The "Government Sale" Scam
Tuk-tuk drivers or friendly strangers tell you about a special government sale or export deal. There is no such thing. Legitimate jewelers don't need touts.
The "Student/Local" Approach
Someone practicing English befriends you and coincidentally has a family member with a jewelry shop. Professional con artists work in teams.
Synthetic/Treated Stone Switch
Stones are switched between showing and setting, or heavily treated stones are sold as natural. Always insist on certified stones and verify certificates.
Inflated "Appraisal" Values
Jeweler provides an appraisal showing 3x the purchase price. These are worthless—legitimate appraisals reflect actual market value.
