Loralite

Loralite is the rarest and strongest gem on Lorien, only found at the planet's core.

It is used to make the Garde's pendants.

It can also increased Eight's range of teleportation, allowing him to teleport from continent to continent. He could only teleport to places that already have Loralite crystal, and he couldn’t control where he went though.

Eight had found Loralite in New Mexico, the coast of Somalia, Easter Island, and a few other places.
