Hannis

Hannis (pronounced /hæˈnɪs/) was a terrestrial planet in the Gecher System, and one made almost entirely of diamond. Due to its location nearby the colonized Nantor and Nantor II, it was quickly mined to near depletion, mainly by the Vectassi Organization, its mass estimated to have been reduced by a quarter within the first few decades, at which point excavations were restricted to avoid gravitational planetary displacement. It is estimated however that by 3000AS it will become a satellite of Nantor and ultimately collide with Nantor II. Its accessability quickly and severely reduced the value of diamond in jewlery, especially to humans and other nearby species, however it was sometimes used it non-automated weaponry and tools for a while after.
