The Sheaffer Imperial Sovereign, IMHO, as they say, ranks among the most aesthetically appealing pens ever made.
The Gold plated 'diamond' pattern is unique, and is echoed by the 14Ct. Gold diamond nib. The facets are sharply defined and act as individual mirrors to reflect the light at different angles. It is very hard to hold the pen and not turn it in the hand to admire the effect. It is a jewel of a pen.
