The scam

A network of touts and con men present the mark with an opportunity to profit from buying discount gems from a jewelry shop. The mark is convinced that he can buy gems at duty free price and bring them overseas for a three-fold or more profit. Through a network of helpers, each of whom tells the mark bits of information, the mark is guided to the jewelry shop.

1. A tout will be on the lookout at popular tourist spots like the Grand Palace, Wat Pho, Khaosan Road, Siam Square, or other temples or tourist attractions in Bangkok. (Also, the scam may often be initiated by a tuk-tuk driver.) The tout will be dressed as a student or gentleman and will approach the mark to tell him the place he is about to visit is closed today because of some made-up holiday. The tout, taking advantage of the Thai people's reputation for friendliness, may strike up a conversation, asking where the mark is from, and if this is his first time in Bangkok. The tout will also tell the mark that a certain tuk-tuk waiting nearby is cheap or even free because it has been sponsored by the tourism ministry and can bring him to other temples elsewhere to visit. Sometimes this gentleman finds out which country the mark is from and informs the con man at the next layer about it.
2. If the mark gets on the tuk-tuk, the driver will bring him to a secluded temple in the city, drop him off, and wait for him to return.
3. When the mark walks into the temple, there will be a gentleman praying inside. That person will tell him about a scheme by the government which allows people to buy jewelry duty free and make a profit when the gems are shipped to their home country, adding that today is the last day of this scheme.
4. The tuk-tuk may take the mark to another temple, where another person (sometimes a Thai, sometimes a Westerner) tells the same story, building up the mark's confidence through a seemingly "independent" verification. If the mark is interested, the person will tell the tuk-tuk driver to take him to the jewelry store.
5. At the shop the mark will be pressured to buy jewelry. If the mark purchases the jewelry, the gem will be packaged and shipped directly to the mark's address in his home country so that he will not have a chance to get the gem appraised or return it for a refund. In the purchase process the mark may be told to go to a nearby gold shop to purchase gold to be exchanged for the gem - this money laundering ensures that any stop-payment on the part of the mark will not affect the gem store's profits.
6. The mark returns to his home country, only to find the jewelry to be worth far less than he paid for it.
