This is an Agate charm. The metal is K10. It's simple yet elegant. I've only used it a few times since purchasing it, and there are no noticeable scratches or stains, and it's in overall good condition. (Please note that there may be minor imperfections due to home storage.) Accessories: Sales certificate Number: 10183117056 I loved it, but I'm selling it to organize my accessories. If anyone is interested, please consider it.
