I purchased this at a department store about 10 years ago. Material: 926 I forgot the type of stone, but it's a lovely pink color♪ The actual color is pinker than in the photos. The size is approximately 16mm, so I think it's about a size 10, but I'm not certain. The silver has faded a bit, but I think it can be cleaned with baking soda, etc. Thank you very much!♡
