Zincite crystallizes in the hexagonal system. |
In the New Jersey mines the zinc ores are the oxides zincite and willemite, and the zinc-iron oxide franklinite. |
It is never found in pure state but rather as zinc carbonate, zinc oxide, zinc silicate, as well as in minerals like franklinite and zincite. |
Despite its striking beauty, zincite remains a rare collector's item. |
