In the history of jewellery, the technique used in the manufacture of this type of piece confers on them a singularly Portuguese aspect. They are cut from gold sheet and invariably worked with leaf motifs over which other elements, formed separately, are overlain.
Throughout the 18th century it was common practice to set these items with diamonds. From the 19th century, a more popular interpretation appears, maintaining the form and ornamental themes, but, for reasons of cost, the precious stones were replaced by imitations or by studs of faceted gold.
