Using gold as an investment is one of the safest way to protect your money, and of course that store fine jewelry (as Menē's) adds extra value. If you are buying jewelry as investment you have to consider all the things listed in this post (even the divorce settlement) to find the best value.
I rather buy bullion coins, but that is because I don't wear jewlery, I have some but just as investment.
Just visited Menē's web site... great designs, simple and elegant.
