I don't remember exactly when I bought it, but I purchased it about 5 years ago at an Agete store in a department store. I believe it was K10 and cost around 35,000 yen. The stones are onyx, emerald, peridot, and labradorite. I don't remember the ring size, but I usually wear a size 12 or 13, and those sizes fit perfectly. I used it when I first bought it, but I've only been storing it recently, so I'm putting it up for sale. I threw away the box, so I will only be sending the ring itself.
