I purchased this at an exhibition for around 100,000 yen. It's a platinum and diamond ring. It has a pt900 1.00 stamp. I believe it's size 6 or 7. I want to sell it quickly, so please feel free to make offers, including price reductions. I will send it with simple packaging. Please understand that this is based on my personal assessment. Please purchase with the understanding that it is a used item.
