Bangkok Gem Scam (Grand Palace Closed Version)
The Bangkok gem scam is possibly the most sophisticated street scam in Asia — it uses no direct threat, involves multiple actors playing roles, and has convinced doctors + lawyers + investment bankers to hand over $500-5,000 for worthless gems. The most common version is the "Grand Palace closed" gambit near the Old City. Despite Bangkok Tourist Police issuing warnings for decades, the scam continues because the victims are usually so embarrassed they don't report.
How the scam works
- 1You approach the Grand Palace early morning (07:00-10:00). A friendly local — usually well-dressed, English-speaking, sometimes claiming to be a teacher, professor, or off-duty policeman — approaches you
- 2They tell you "The Grand Palace is closed today for a Buddhist ceremony/royal visit" (it's not) but you can visit "some special temples" instead
- 3They hail a "special tourist tuk-tuk" (part of the scam) for the day at a suspiciously low price (฿20-50 for hours)
- 4The tuk-tuk takes you to 2-3 minor temples (real temples) as a set-up. At one, another "helpful local" — supposedly Indian gem merchant or Thai jewellery businessman — starts a conversation
- 5The businessman explains he's "wholesaling to the West" and can offer you rubies/sapphires at 50-70% below retail. He shows you a certificate of authenticity + arranges private taxi to his shop
- 6At the shop: high-pressure sales + fake gemological certificates + a promise to send the gems to your home country where they can be sold at a huge profit
- 7You buy $500-5,000 worth. The gems are worthless synthetic corundum or heavily-treated low-grade material. Value in your home country: $30-100 max.
Red flags — how to spot it early
- âš Anyone approaching you unprompted at the Grand Palace, Wat Pho, or Wat Arun with claims of closure
- ⚠A tuk-tuk driver offering hours of transport for ฿20-100 (real fares are ฿150-400 for the same journey)
- âš "Coincidental" encounters with gem/jewellery businessmen
- âš ANY claim about "wholesale prices" or "reselling for profit in your country"
- âš Certificates of authenticity issued by names you don't recognise
- âš Being taken to a private residence or "office" for gem viewing
How to avoid it
- The Grand Palace opens 08:30-16:00 daily EXCEPT for Coronation Day (Dec 5) and King's Birthday (July 28) and rare royal ceremonies. Check the official website (royalgrandpalace.th) before travelling
- Ignore anyone approaching you unprompted with information about "closures" or "special ceremonies"
- Never board a tuk-tuk for a full-day tour at implausible prices — real prices are ฿150-400/hour
- Never enter a gem shop that's not on your independent research list. Real Bangkok jewellery: Mahaesak Road (silver), Charoen Krung (fine jewellery)
- Never buy gems for "resale abroad" — regardless of country, this is always fraud
If it happens to you
- →If you've been sold gems: contact the shop within 48h claiming you want to return them. Some scam shops offer partial refunds to avoid escalation.
- →File a complaint with Bangkok Tourist Police (1155 or 02-138-5088) with receipt + shop address. Enforcement is inconsistent but reporting matters.
- →Contact your credit card company IMMEDIATELY to dispute the charge — success rate is 50-70% for gem scam disputes within 60 days
- →If gems are genuine but overpriced: get them independently appraised in your home country. If value is under 30% of what you paid: charge dispute
- →Report on the Bangkok Tourism forums + Reddit r/thailandtourism to warn future travellers

Frequently asked
Why do smart people fall for the Bangkok gem scam?
Multiple factors: (1) jet lag reduces critical thinking, (2) the scam uses respectable actors (teachers, businessmen) rather than obviously seedy characters, (3) the wholesaler pitch appeals to intelligence + investment instinct, (4) the victim gets progressively invested in the story over 2-3 hours, making it hard to back out. Doctors, lawyers, and finance professionals are documented victims.
Is the Grand Palace really closed for Buddhist ceremonies?
Almost never for tourists. The Grand Palace is open 08:30-16:00 daily except for coronation, king's birthday, and rare royal state ceremonies. Anyone telling you it's closed unprompted is running the scam. Check official website royalgrandpalace.th or call +66 2 623 5500.
Can I get my money back from a Bangkok gem scam?
Partial. Credit card dispute within 60 days: 50-70% success. Shop refund on return within 48h: 20-40% success. Legal action: very difficult due to complex chain of shops + weak Thai consumer protection. The single best action: dispute with your credit card provider immediately.
Where CAN I safely buy jewellery in Bangkok?
Real jewellery districts: Charoen Krung (fine jewellery), Mahaesak Road (silver), Chatuchak Weekend Market (costume). For actual gems: go to the Asian Institute of Gemological Sciences (AIGS) in Silom for authentic + certified stones. Never buy gems from a shop you were "taken to" by a stranger.
