I have a European jeweler friend who is interested in buying gemstones at better prices than he can get in Europe. He wants me to travel with him to Dubai as he has never been in the Middle East and is leery of it. I just want to make sure that we don't run afoul of national laws in Dubai when it comes to exporting gemstones in bulk (probably stones from Afghanistan, Madagascar, East Africa and/or Sri Lanka). Where can I find the rules and regulations that apply? Thanks.
