Metal?,clay? But beautiful

I think these two pieces are beautiful and odd,I am not even sure if they are metal of some type since the inside of both are a beautiful gold bronze shiney color and the outside surface is roughly grainy texture,a place called Kennard and Franky were the company that does my aunt's interior design and I'm sure they were the company who purchased them but since my aunt is no longer here I will never know for sure.I have yet to see another pair this odd is about all I know about these two.there are no apparent markings,any information would be greatly appreciated
