It is the black Starwalker with a diamond in the acrylic dome of the cap; MSRP is 495 euros for the fountain pen and 395 euros for the ballpoint. Collectors report that the diamond "floats" beautifully in the acrylic body and shows off its facets, in contrast to the embedded diamond of the Solitaire Granit 1906 Edition. Delivery is expected in early April with the start of Montblanc's new business year. The silver-coloured Starwalker visible in the photo belongs to the 100 anniversary editions and is not identical to the black special anniversary edition.
