I have already read these two questions: If I don't declare a not-yet-used engagement ring at airport security, am I smuggling jewelry? and How do I get an engagement ring past security/customs in an airport without alerting my significant other?, and I saw some valuable advices, but now I want to ask specifically for Russia.
My friends and I are going to Russia, and my friend would like to propose his girlfriend there. What would be procedure so that his girlfriend doesn't find out of course. I have read somewhere that a person can import goods in a value of 1500 US$ and not to declare it, above that you have to declare goods. Ring is of value around 700 US$.
How to proceed?
