There are some Montblanc customers who are extremely fond of gemstones and only want to buy and collect pens that possess gemstones. Boheme is a typical pen line in owning these valuable natural minerals.
The stone you are seeing is from the pen model. Bohemian Bleu, a fresh and peaceful blue sapphire. The special feature of the Boheme pen line is that the artisans will grind the gemstones to fit the pen clip perfectly, without using any glue or chemicals to attach it. At the same time, the selected stone is also of the highest quality with suitable size and clarity.
This pen line is now discontinued, so the Boheme Bleu pen is becoming increasingly rare. If you are still hesitating, decide now!
