# Sandstone vs. CVD Diamond

Sandstone belongs to the natural stone classification, while CVD diamond belongs to the non-oxide engineering ceramics. There are 13 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is sandstone and the bottom bar is CVD diamond.
