The municipality’s arms might in English heraldic language be described thus: Below a chief countercompony azure and Or, Or a bend gules between a torc and a Gothic letter C, both sable.
The chief with the countercompony pattern (that is, two horizontal chequered rows) is a reference to the village’s former allegiance to the “Further” County of Sponheim and the Amt of Kirchberg.
The black torc (of the Wendelring type) refers to the wealth of archaeological finds made in the grave field from the Hunsrück-Eifel Culture near the Eichelberg.
