This is the ebine 3-way Studs Zirconia Ring (^^) The color is silver, and the size is size 13. I recently purchased this, but I'm selling it because the size didn't fit. From the official website: A versatile ring that can be used in 3 ways. You can use it as a stud ring, a zirconia ring, or even half & half. The material is surgical stainless steel 316L, so it is resistant to sweat and water, and you can wear it in the bath or while playing sports without any problems. It is also a material with extremely low allergenicity, so it can be used by people with metal allergies. (Individual differences apply.) I have disposed of the original bag, so I will put it in a waterproof bag and pack it with bubble wrap before shipping.
