I purchased this from Canal 4°C. I've included a photo of the sales certificate. Product number: 151924441002 I wore it for about a month. One of the stones has fallen out. I want to sell it quickly, so comments are welcome! There is no box. This is just the ring. I will send it via Yu-Packet Post Mini, so I will wrap it in bubble wrap and use simple packaging. (Waterproof packaging) Thank you!
