The beads in this onyx strand have a diameter of 8mm and a matte finish; the total length of the onyx strand is about 40cm.
Onyx (set) is one of the classics of gemstone jewelry, as the black color combines well with many other types of stones and the wholesale price is very reasonable.
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.
