This is a single-diamond necklace made of silver. It has a ball chain, but instead of a plain round ball chain, it's a cut ball chain that sparkles, making the chain look very beautiful. I was fascinated by diamonds in my 20s and bought many, but in my 30s, I started wearing the ones my husband gave me. I'm now offering the ones I bought myself to someone who will wear them. I'm selling it very cheaply, so if you'd like to wear a diamond, please consider it.
