GRAF VON FABER CASTELL  LIMITED EDITION  PEN OF THE YEAR 2007 PETRIFIED WOOD  FOUNTAIN PEN XXXI  

Faber-Castell's legacy of transforming the living material of wood into the finest writing instruments reaches a new pinnacle of beauty in the form of petrified Brazilian deciduous wood. The dark colouring and hardness of this wood when refined presents a gemstone finish of the highest quality. Individual hues vary from light brown through anthracite to deep black, all with a characteristic sparkle. A platinum-plated frame encases eight "stones" of the precious material and the end of the cap features the material faceted as a diamond and polished to a mirror finish. The logo of the Herbert Stephan Gemstone Manufacturer, guaranteeing the genuineness of the fossil material, can be seen on the inside of the this end cap plate. The plunger-action fountain pen features an 18k bi-coloured nib and is enclosed in an exclusive wooden case with a brochure and certificate of limitation and authenticity.

Petrified wood comes about in a crystallization process lasting up to 360 million years. Wood covered by water or ash undergoes a unique metamorphosis when minerals, metals, lime, or phosphorus penetrate the wood through layers of sediment. The materials gradually replace the wood but leave some of the organic structure intact. In a silica-rich environment, the petrified wood begins to develop into the preliminary stages of semi-precious chalcedony or agate.
