feature of onyx is the alternation of black bands, or very brown, with white
bands. Other chalcedonies can mingle with onyx by forming layers of different
colors. The names of these varieties evoke their associations:

Confusions and Deceitful Appellations
black and white striped onyx sometimes takes the name of onyx “arabic or
arabica” or “oriental onyx”. But there are many misleading names
and confusions. For example:
- Black onyx is often called black monochrome chalcedony.
- The “onyx of Peru” is actually a pale pink stone
from the group of carbonates called manganocalcite.
- The onyx-marble also called “onyx limestone”
or “onyx-marble” consists of a mixture of calcite and aragonite, its
composition has nothing to do with that of onyx. No more than the spurious
“Mexican onyx” which is also similar to the marbles?
The onyx becomes scarce hence the temptation to
produce it artificially. Solutions of ammonium chloride and cobalt are used to
obtain a dark color, often unstable over time, on a chalcedony or a uniform
agate. A regular clear coat is then removed by removing the excess shade with
