Some parts of the Touareg crafting are performed by specialists; this also includes the manufacturing of upper arm bracelets.
Stone plates of different colours are broken into the fitting size and the raw form of the bracelet is worked out with a how-axe, until the inner core of the bracelet is falling out. After the finishing with a file, the bracelet gets greased or blackened with soot.
The Touareg men wear these rings at the upper arm; usually it is placed in a short distance to the elbow. The bracelets are said to have a protective effect against evil ghosts; and of course they are also worn due to their decorative effect.
Since several years, the stone cores, which are a by-product of the manufacturing, are used to create stone amulets similar to the silver Touareg-Crosses (also known as “Agadez-Cross”).
