Diamond rod
A diamond rod is a straight or curved rod with inlaid or protruding cut gemstones ( goldsmith's art ) or with decorations in the form of cut gemstones (architectural ornament).
Occurrence
Diamond bars are a typical element of ivory and goldsmithing. They are also used as architectural ornaments in the architecture of the Romanesque period in Western and Southern Europe. In the Gothic architecture and Baroque they hardly play a role; they reappear only in the art of historicism .

meaning
Diamond rods clearly have sovereign-representative implications and can therefore be found on particularly valuable jewelry or on church portals, etc.
Others
In the architecture of the Renaissance , entire facade surfaces are occasionally covered with stone spikes (e.g. the Casa de los Picos in Segovia , the Casa de las Conchas in Salamanca or the Palazzo dei Diamanti ) in Ferrara .
