Omas Marte Pen
The gorgeous pen shown here is the latest from Omas, a celebration of the red planet, Mars. The pen's rose gold surface has been crafted to serve as a map of the planet, with deserts, mountains and craters. The frozen caps of the planet are done in a cluster of two-carats-worth of diamonds clustered on the pen cap and the base of the pen. Four small rubies on the pen celebrate the four landing points of Martian probes. It also comes in a Mars-shaped box.
