Labbe necklaces made of applied filigree, being open and airy like the interlaced net of a spider's web, became more popular during the Ottoman conquest of Yemen in the mid-19th century, and were given the name labbat šabek in Sana'a, after its technique. Until then, most were prepared by using casting techniques, and embossing and fashioning from solid pieces.[1] Only a few were made from silver.[13] The labbe is traditionally made from dozens of components arranged in horizontal rows, or storeys (projected lines). The top row forms the base of the necklace, with connecting parts (usually serial pendants) densely strung upon a cotton or silk thread, extending downwards lengthwise, in identical columns forming the horizontal lines.
