Rusty Davidson (Black Diamond Gallery) has some incredibly beautiful furniture carved out of stone and teak, which apparently doesn't rot, and if it were buried in the ground, after 1000 years, it would turn to petrified wood. Check it out: http://blackdiamondgallery.com/subs/Furniture.html
Just finished checking the website and those carved stone and teak furniture pieces are amazing. The details are right on and love the rich dark palettes as well. Thanks for sharing.
