Chimerium
Chimerium was a luminescent orange crystalline mineral. It was valued in a region of the Delta Quadrant, with a single large crystal sufficient to purchase a small starship. It could also be used to create a chimerium cloak.

Tars Lamora was rich in chimerium, particularly in the deep core. It was mined by slave labor at a prison colony ruled by the Diviner, who used it to pay the Kazon who brought him more slaves. After losing the  in 2383, he ordered chimerium extraction at the colony redoubled as he would need every speck to finance its retrieval. ()

Klingon cloaking devices required chimerium to function. ()
