A class and Gems

Gems are mineral life forms composed of inorganic crystals. They are human-shaped, approximately 150 centimeters tall, and have characteristics dependent on the material from which they are made.
There are 28 gemstones in the world, each of which is unique in composition and characteristics.
The Lunarians are the main enemies of the gems: they steal them to use as decorations.
Gems can be restored from fragments, but lost fragments lead to memory loss.
Mohs hardness determines the role of the gem: soft (2–5) perform peaceful tasks, medium (5–8) patrol, hard (8–10) fight.
