It is one of my favourites…
Visconti designed a fountain pen taking Insipiration from the golden number (phi) and the nautilus
The Golden number derived from the Fibonacci sequence (also known as golden ratio or phi/pi 1.618) was applied to this writing instrument , the relationship between the length of the cap and length of the pen (both open and close) respects the divine proportion ( probably this was the first time this logic was used in a writing instrument)
The really captivating feature of this pen is nautilus inspired spiral that beautifully envelops the pen.
The spiral is made of silver which is inlaid into the lucite made body of the pen (lucite is the purest or highest grade of resin)
Because of use of phi to design the pen (phi also called as divine proportion), the pen was named Divina.
Versions of Divina
1. The first one Divina black has been the best seller among the divina series which came in two sizes : midi and oversize.
2. Colours (blue, green, plum) were introduced in this model and were called divina excellence.
3. Limited editions in this model were very beautiful yet again made from celluloid, the divina desert spring and divina ‘divine proporzione‘.
4. A special divina black was released at G8 summit where president Barack Obama signed the G8 document with it.
Ink filling mechanism
Pull and Turn (as described by Visconti) is similar to a captive convertor.
Since these are modern production runs and some models still available, i am not putting a rarity quotient or collector quotient to it. However if you are someone who is fond of maths, science or Leonardo da Vinci, this pen is a recommended pen to be a part of one’s collection.
