Made of stone

Brief

<b>Submitted images must show things that have been made using stone, rather than simply stone itself, in nature or excavated. </b> That most fundamental of materials, which for millennia has been used for our good. We build walls to house us, carve it in commemoration of the dead, we grind spices in stone bowls, sculpt art from it, and in the past ground our crops between huge wheels of it.
