II-Grade dark ochre, also known as onyx ochre, has a distinctive, shiny black surface that lends itself to ornamental uses. But the 5% higher mineral yield is what miners are really after. Like in all else, good looks are only an added bonus.

Isogen and
Mexallon inside it. Dark ochre also contains useful amounts of
Nocxium.
