A brooch is an item of jewelry, a large ornamental pin or clasp. In period armory, it takes the form of a “closed brooch” or “ring brooch”, with the pin piercing the field as though it were fabric, as in the illustration. It is found c.1370, and again in 1605, in the arms of von Zedlitz [Gelre 53v, Siebmacher 71].
Of the brooches unique to Society armory, the most common is the “penannular brooch”: a semi-circle of metal, with a sliding pin. The penannular brooch has its opening to chief by Society default. It may be found “closed”, with the pin overlying the brooch, or “open”, with the pin through the gap; closed is the default.
Other brooches have been blazoned by their general description: e.g., the “Celtic triquetrum brooch”, a description of the metalwork’s design; or the “Moorish hair-brooch”, an adornment for the hair. These brooch variants are no longer permitted in Society heraldry, being insufficiently documented.
