A pen is mightier than a sword, and a crystal-studded pen is bound to be a powerful tool for linking thoughts. We came across this beautifully crafted writing device recently at Alfred Dunhill is more than the conventional fountain pen you’ve resorted to before. Inspired by the British letterbox, the Sentryman Swarovski Diamond Fountain Pen sports 112 black diamonds set in the logo cap. With a barrel wrapped completely with Swarovski black crystal fabric, the Sentryman Swarovski Diamond Fountain Pen will be limited to just 112 pieces and is available in a lacquer box. Complete with a limited edition certificate included to portray the pen’s exclusivity, the Sentryman Swarovski Diamond Fountain Pen is priced at $5,000 apiece.
