Etymology
The carbunkel was a mythical creature reportedly sighted in the Americas by Spanish conquistadors. It is described as a small creature, either a bird or a mammal, that has a gem in its forehead crystallized from the brain of a dead dragon. According to superstition, it is good luck to catch a carbunkel.

Carbuncle is also an archaic term usually taken to describe any unfaceted and convex gemstone, particularly those red or garnet in color.
