If one is looking to indulge in the world of extreme luxury and refinement, the David Oscarson diamond fountain pen is a good starting point. The incredibly extravagant writing tool is crafted out of 18 karats yellow gold and 35 karats of precious stones that vary in hues to create a beautiful diamond-encrusted artwork of nine scallop-shaped shells. In addition, the David Oscarson creation boasts an appropriate 18 karat gold nib and an ebonite feeder.
The process of developing the pen took the designer about one and a half years. The seaside-inspired diamond fountain pen is also one-of-a-kind, which is yet another feature that aims to justify its mind-boggling retail price. The ultra-luxurious writing tool is currently being sold on eBay for $755,000 USD.
