Nice to meet you! - ̗̀(ᵔ⌔ᵔ) This is an agate filigree ring. The purchase date is unknown. The material is K10, YG. I don't remember the size exactly, but it feels about the same size as my other size 9 rings, so I think it's probably a size 9 (*_ _)՞՞ A 0.008ct diamond is set in the center. The box is not included. If it doesn't sell in about two weeks, I plan to take it to a recycle shop.
