There's nothing to guarantee. I bought a ring and necklace at Tianhe store in Dalingshan three years ago and gave it to him for maintenance. They denied this and said it was not marked JY. Not when I said I bought it! Did you all sell fakes a few years ago, denying that you never sold gold without JY logo? You are speechless.

Gold leaf jewelry is of poor quality and easy to spend. I bought a ring necklace a few years ago. It looks like stainless steel. It's not bright at all!
