Carbuncle (heraldry)

A carbuncle or escarbuncle is a heraldic charge consisting of eight radiating rods or spokes, four of which make a common cross and the other four a saltire. The ends typically terminate in a fleur-de-lis or some other decorative form. Frequently the centrepoint is adorned with a jewel; the name may therefore be a reference to a carbuncle gemstone.
