Natural stone window or man-made stone good?
Look at your usual use of the windowsill often put things on the artificial stone can be used most of the natural (but there is a gap between the natural particles oh)
I use the artificial stone. Feel good. The window is so narrow and do not put any weight
I installed a large flower black sand 350 a flat, two sides of the copper bar plus a meter of self feel good, in the window of the sun shining on the gold, and the wall foil can better reflect the effect of the 35.
