Featuring a sterling silver cap which has been engine-turned in the traditional way with a distinctive diamond-shaped engraved pattern that shimmers as you turn the pen in your hand. The tri-colour barrel is made by diffusion-bonding black, white and pearlescent silver-grey acrylic to complement the sterling silver cap. The 23 carat gold-plated Onoto chevron clip and the gold-plated Onoto cipher on top of the cap just add to the royal ‘feel’. There is also a real diamond embedded in the clip, just below the distinctive Onoto chevron.
