The Tibaldi Fulgor Nocturnus (Latin translation for “Night Glowâ€) pen is based on Tibaldi’s Divina pen which embodies the ancient concept of the Divine Proportion allowing the pen to rest comfortably in ones hand. The pen is made of solid ruthenium plated eighteen karat gold encrusted with nine hundred and forty five black diamonds on cap and one thousand one hundred and thirteen on the barrel whilst one hundred and twenty three rubies decorate the ring around the clip and sixteen form the button of the cap. The pen has a gold nib which is partly plated with platinum and rhodium and uses Tibaldi’s innovative and highly precise filling mechanism, the pen is a unique creation.
