Madagascar agate also known as Sardonyx sphere. Comes with a small clear sphere stand. 

This beautiful agate sphere has great red and white banding and is polished to a mirror like finish. 

These smaller Madagascar spheres are getting harder and harder to find especially this quality. Most of the ones found now do not have the deep red with white banding anymore. I was only able to find 6 small spheres of this quality this year in Tucson. 

This sphere weighs 1.3 ounces

And is 1.1 inches
