Just arrive from Madagascar this slice of fossil wood, from the ‘Araucaria’ or Monkey puzzle tree, is truly fantastic. Cut and polished on both sides to reveal the warm creams and golds. The preservation is so good that you can almost count the growth rings. The hole in the centre has, very unusually, been replaced by a stunning banded agate. Weighing in at over 10kg and 54cm across at its widest point this is a very impressive piece of 250 million-year-old fossil wood from the North West coast of Madagascar.
