Rule of thumb — if you can’t imagine living without your grandmother’s wedding ring or your expensive Movado watch, it’s best not to cart it on your trip, where tourists are common targets for thieves and luggage often gets lost in transit. You may think you look like an icon of style, but to criminals and con-artists you appear as an icon of opportunity. It’s also wise not to look like a million bucks if you’re trying to bargain with the locals, and sparkly jewelry may set you apart from other folks on the street when you’re trying to fit in. If you must bring your jewelry, keep it in the hotel safe except for special occasions such as dinner in a nice restaurant, and be sure it’s covered by appropriate insurance. Most homeowners’ policies will not cover jewelry if it’s lost or stolen while traveling, so you may need to purchase a separate policy.
Pack any valuables you buy while on your trip (and any of your own that you decide to bring) in your carry-on. As we all know, checked bags sometimes disappear into the mysterious black hole of lost luggage.
