Antarcticite

Hardness: 3

Antarcticite is the gem assigned to winter duty while the others hibernate. Due to their crystal composition, Antarc "sleeps" in liquid form when it is above room-temperatures, and re-crystallizes when the temperature drops. The colder the temperature, the harder they become.

Antarc is a perfectionist who acts like a soldier, marching and speaking with extreme formality. They are used to working alone, as all the other gems hibernate during the winter. Despite their usual cold attitude, Antarc has a soft side, and they love Kongou more than anything, often breaking their usual icy demeanor around him. They do not like to openly show this softer side though, becoming extremely embarrassed when Phos sees them like that.
