This is a clear stone design ring with a voluminous look. Although there is no hallmark, I was told it was silver925 at the time of purchase... Since there is no hallmark, the material of both the metal and the stone is unknown. *Although cleaned, please refrain from purchasing if you are concerned about scratches or unique blackening, as this is a used item. It's one of my favorites, but I have too many accessories, so I'm selling it to declutter. I may change my mind and cancel the listing, so if you are considering purchasing, please do so as soon as possible...
