Each bead is unique and can be very different from the picture.

The onyx belongs to the Chalcedony family. This stone can come in several colours: transparent, white, black with white or brown stains.
In order to give them a uniform black colour, black onyx beads and stones are dyed thanks to a long treatment process.
