It is heavy i would say easy 15 lbs the stone is marble tiles the internal is unknown but i am thinking ceramic. The arm stubs are brass. Yes it was purchased at a yard sale for 20.00. I paid 35.00 for it cause i thought it was neat. I may just mark it with a price of 100.00 and use it as a jewelry stand in the mean time. I have a upper scale thrift store so it will look good in one of my cases as such.

PS Thanks all for the input!! I welcome any new input as well.

I came across this via one of my yard sale pickers. It is made of stone, mother of pearl with brass inlays. it stands 19" tall

Here  are the pics of mine.
