The Sarma or Serma is a cone-shaped metallic headdress that originated in Algiers.

[1] The Sarma was mostly worn by Algerian women during the Ottoman period in Algeria.

The Sarma is composed of two parts, the first being a truncated and hollow half-cone which is held against the head by thin scarves or bands and resting on the forehead.

[1] The second part is used to contain the hair and consists of a thin silver plate pierced with arabesque motifs.

[1] Stephen D’Estry observed that the headdress of the Jewish women of Algiers, the Sarma, resembled a cone shape and was adorned with a transparent veil enriched with embroidery.
