It's hard to say. Not the place of origin. It won't be too good. Who goes deep into these luxury goods markets? Some sell fakes, and some shoddy. Jewelry is also graded. For example, if you are a layman, you can't say that he sells fakes at the price of B-class goods sold to you. If you want the real thing, you should either find an insider to buy it or go to a big business. People who don't know the goods don't listen to the store's bluff.
