The chevron beads or rosetta are beads whose section shows the drawing of a star, most often with 12 branches. They consist of several layers around a central axis. The number of layers varies from 4 to 9 depending on the type of beads and their age. In Africa, these beads had a magic value that would be due to the 12 branches of the star. Allusion to the 12 signs of the zodiac, or the 12 solar houses? Nobody knows. The largest were reserved for kings and notables. They could be part of the dowry of a marriage and can be found in the graves. Today, these beads are still highly sought after.
The most common are blue but you can find green, red and even yellow. Some contemporary glass artists are still inspired by them.
