Tiffany & Co. diamond wedding ring

I purchased this, wore it once or twice, and have kept it in storage ever since. There is a slight dent on the case due to improper storage. I paid 6,250,000 KRW (Shinsegae Gangnam Branch). I have the receipt, so I can show it to you. The inner diameter of the ring seems to be about 1.6-1.7 cm. You can have the size adjusted at the store. Please consider this carefully and contact me. Condition: Almost brand new
