This is my own design, made for Björn Segerblad, a journalist in Stockholm.
An English blazon would be as follows: Shield: Gyronny argent and azure, a wreath of laurel counterchanged.
Crest: A pair of eagle's wings displayed gyronny azure and argent. (In this rendering shown in profile, because of the position of the helm.)
Helm wreath: azure and argent. Mantling: azure, lined argent.
(Thanks to the rec.heraldry community for their input!)
These arms are made for a friend of mine as a slightly modified version of the arms recorded in Siebmacher's Wappenbuch for her family, Gellert.
Siebmacher includes three different arms for the Gellert family, the arms used by Mag. Christian Gellert (1671-1759), a vicar in Hainichen, those used by his son, the famous author, Professor Christian Fürchtegott Gellert (1715-1769) in Leipzig -- neither of which is heraldically particularly satisfactory -- and the arms illustrated here, which are designated as "the original arms of the family" citing as the source information from the family and quoting an unverified reference to unspecified "alten Wappenbücher". The German blazon is as follows: "in B. einen s. Balken begleitet von drei (2, 1) 'gehlen' (redend!) oder g. Rosen. Helm: r.-bekleideter Arm mit g. Aufschlag und b. Bausch, einen Zweig mit einer g. Rose haltend. Wulst: b. g. Decken: r. b. - b. g."
Whatever the age of these arms and the correctness of the cited information, they had clearly been assumed by the family by the time this volume (5. Bd, 3. Abt., Nürnberg 1888) of Siebmacher's Wappenbuch was published.
The mantling has here been rendered entirely in azure and or, in spite of the quoted blazon.
