This pools of light ring was purchased from Ruby Lane. It is so sweet. The rock crystal glows in the light. It is an older piece and the rock crystal has some nicks in the stone. You will not notice this while wearing it. I have a feeling they were in the stone prior to setting but I have no idea. Photo #4 shows what I mean - notice how the claw prong is hugging the stone where the nick is- it is as if it maybe happened when they set the stone or they set the stone with the prongs purposely hiding the area? The claw prong has a good grip there and I had no issues while wearing. All I see while wearing it is the wonderful glow of the rock crystal (natural from the earth). It is a lovely ring for someone that appreciates the glow of pools of light pieces. Very comfortable and sweet. 925 sterling Silver/size 5. Please write with any questions. Private seller, no returns.
