Carbuncle \Car"bun*cle\, n. [L. carbunculus a little coal, a
bright kind of precious stone, a kind of tumor, dim. of carbo
coal: cf. F. carboncle. See {Carbon}.]
[1913 Webster]
1. (Min.) A beautiful gem of a deep red color (with a mixture
of scarlet) called by the Greeks anthrax; found in the
East Indies. When held up to the sun, it loses its deep
tinge, and becomes of the color of burning coal. The name
belongs for the most part to ruby sapphire, though it has
been also given to red spinel and garnet.
[1913 Webster]
2. (Med.) A very painful acute local inflammation of the
subcutaneous tissue, esp. of the trunk or back of the
neck, characterized by brawny hardness of the affected
parts, sloughing of the skin and deeper tissues, and
marked constitutional depression. It differs from a boil
in size, tendency to spread, and the absence of a central
core, and is frequently fatal. It is also called
{anthrax}.
[1913 Webster]
3. (Her.) A charge or bearing supposed to represent the
precious stone. It has eight scepters or staves radiating
from a common center. Called also {escarbuncle}.
