Each Metal Silver or Gold Crystal Sphere Stand measures ~2.07" Wide as measured from the outside of one prong to another, 1.17" diameter of interior ring as measured from the outside edge.

This listing does NOT include any of the pictured spheres.  Only the Sphere Stands themselves are included in the quantity and style that you select.  For reference the spheres pictured here are between 35.8mm(1.41") and 67mm(2.65") with the one largest Mookaite Jasper Sphere being 77.7mm(3.06"). This would be the recommended range to look best on this sphere stand.
