You humans cut stones to unlock their beauty... but trolls cut stones to unlock their POWER.
Vendel to Jim[src]

Gemstones are precious (or semiprecious) stones that are cut and polished materials.

While humans cut stones to find beauty within them, trolls cut them to unlock special powers. As such, Trollhunters often use these gemstones to acquire upgrades for their armor and claim new weapons.


Gemstones have been in existence ever since the formation of the Earth.

Trolls discovered gemstones much before humans did, and used them to grant themselves great powers. Later, humans discovered these stones, but instead of using them for their power, they used them for their aesthetic appeal.


Gemstones come in various shapes, sizes and colors. They have mystical properties which can only be unlocked by correct cleaving. They can also be cut to further enhance their natural beauty. They have varying degrees of rarity and the rarest ones are often very valuable.

List of Stones/Gemstones[]

  • Heartstones: These enormous stones are the very life-force of trollkind and the means that keeps them from perishing.
  • Triumbric Stones: These three ancient stones are tied to Gunmar's lifeblood as they each correspond to a specific action he has committed. When all three are brought together and cleaved, they unlock the Eclipse Blade, the only weapon capable of wounding or killing Gunmar.
  • Eye of Angor Rot: It is discovered that Angor Rot's own eyeball contains a gemstone within, which (if cut properly) can be used to counteract his magicks, including his cursed mark.
  • Eyestone: This stone is the final piece of the Killahead Bridge, which is able to partially open the portal to the Darklands, but not completely without the Amulet of Daylight and its master.
