Green malachite is prized for its vivid green colour and unique banded patterns, both of which arise from its crystalline structure.

The subtle variations in hue are due to the fluctuations in the chemical composition–specifically, the copper content–where a higher concentration of copper results in a deeper green, while lower amounts produce a lighter shade.

The striking banded patterns themselves are formed during the crystallisation process, making each malachite dial visually unique.
