Packing unit with 0,5kg; this is about 140 - 160 black Onyx Tumbled Stones.

The name Onyx is derived from the Greek word "onyx" for "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.
Onyx (black chalcedony) supports assertiveness and strengthens the sense of responsibility. Other themes of black Onyx are logic, control and sober thinking.
