You are looking at a sterling silver .925 Multi-Color Cubic Zirconium Slider. This shiny silver ball slider has an opening that is about 4mm in diameter. The ball is about 8mm across and there are 15 cubic zirconium set on the surface. The CZs are purple, green, amber, and blue. The approximate weight of the slider is 2.1 grams. This is a very pretty sliding pendant.
This pendant/slider would fit any chain that can be put through a 4mm diameter opening. It would be a great gift for anyone who loves these pretty sliding bead pendants.
