Aurora is a pen manufacturer based in Italy known for its luxury writing instruments. The company’s Diamante fountain pen is known for its smooth flow of writing delivery, though it may be hard to concentrate on your penmanship with this pen when it has around 2,000 diamonds encrusted all over its body. Yes, 2,000 diamonds, making this pen not just a writing instrument, but a veritable jewelry as well. To top off the statement of wealth that this pen seems to proclaim, the nib of the fountain pen comes in gold. Only one Diamante pen is created each year by the manufacturer, thus making it a rare collectible.
