I made the mistake of purchasing a Cartier ring from Harrods online. When I received it, there were two areas of scratching I noticed, but they were so difficult to see, I wasn't actually that bothered. However, I returned the ring because it was actually too big, intent on ordering another size once my refund was processed. On receipt of my return Harrods wrote to me to say the ring was being sent for brand assessment, then a few days later, they wrote to me to say they were sending the ring back out to me because there were scratches on it and they couldn't resell it. Unfortunately I have no evidence that the scratches existed when I originally received the ring, but nor does Harrods have any evidence that the scratches did not exist when the ring was originally sent to me. All they can say is it went through quality checking and passed. I believe Harrods are being dishonest with me and that they sent me a ring that wasn't fit for sale, but are relying on their big name and processes to veil their misconduct towards me. On top of this, they just ignored my response to their email, and now I have the pleasure of paying a lot of money for a ring which is too big and has scratching on it. This business is behaving like crooked market traders, a mafia. Steer clear and spend your money in-store (but not at Harrods).
