Buying and selling rough diamond takes substantial experience to understand the hazards and values of individual pieces. In foreign countries, especially third-world countries, be very careful of the scams that take place on a daily basis. Law enforcement in certain areas may be poor, so don’t expect a lot of help if you have been involved in a ruse. It is always best to travel with someone who knows the country and has previously dealt with reputable area dealers. Many so- called rough dealers are simply scam artists waiting for their next victim to arrive.
