This very special set of bookends was mined within the U.S. and derives from a bog. Green Bog Jasper features an amazing colorway in a stone formed in the Miocene age 11 - 14 million years ago. Wood, canes, cattails and creatures living in the bog were all petrified. The teal to lime green color of the material is caused by a combination of iron, aluminium, potassium, sodium and calcium.
