This beautiful rose gold pen has been released by Omas, and comes in its own Mars-shaped box. The pen is named Marte, which is Italian for Mars, the red planet. It sports four rubies symbolizing the four landing points of the Martian probes. An artistic map of the planet, featuring craters, mountains and deserts has been etched on the surface of the pen. The spray of two carats of brilliant diamonds on the base of the pen and its cap stand for the frozen carbon dioxide caps.
