I have bought some incredible authentic things on real real at unreal discounts. I have a 10k amazing mikimoto south sea pearl that I remade into a pendant. My jeweler said it is on exceptionally high quality. $1200. I recently bought a very high end watch that retails for $11k. I got it for $6k, never worn and still has a manuf warranty. I am selective, I order things in newest condition or with tags. I have also bought ferragamo purses. Hermes scarves. And China.
They are great at returns. Never had an issue. But you have to read the description carefully and zoom in the pics.
