I was in Cairo last week on a business trip. My colleague in Cairo recommended a tour guide to see the sights for a day and lent me his driver. The guide was excellent, who not only explained the sights, but took me to a store when I told her that I wanted to buy some jewelry for my spouse (who didn't want me to take this trip, so I wanted to make it worthwhile for her). The guide told me that the merchant was registered with the Egyptian government and carried only high end legitimate pieces. I ended up buying a 18K gold necklace, ring, and bracelet for almost $4,000. The merchant told me that the items were below market value in the US. When I got home, my spouse was livid, saying that there was no stamp on the jewelry and that I had gotten ripped off. I called my credit card company, who urged me to contact the seller and come to an agreement before protesting the deal. I took the items to a jewelry store at home for an insurance appraisal (which I haven't received yet). I am sure that if the gold is less than 18K I can refuse to pay. But what if the value isn't as represented by the merchant? Has anyone had any experience with this problem?
