The window balls made of black Onyx (gef.) have a diameter of 12mm.
The onyx strands are 40cm long and strung for transport. We recommend replacing the transport thread of the onyx strand with suitable knotting material.
The name Onyx is derived from the Greek word "onyx" meaning "nail"; presumably this name, which has been in use for many centuries, refers to the surface of the polished stone, which resembles shiny fingernails. Spellings like onix or onyk are therefore not correct.
