Nature provides many different green minerals. The hues of these ground minerals range from green to greenish gray. In general, the coloring effect of these powders is caused by iron-II-silicates. In case of Verona Green Earth, the color is a result of the mineral celadonite. In contrast to the frequently occurring ochers, green earths are rare and hard to procure.

Verona Green Earth can be found in the mountains north of Verona, its source being well-known since antiquity. However, the bluish, best quality of Verona is no longer available due to the landslide following the earthquake in 1922. The qualities accessible today, which lack the distinctive blue tint, are similar to the historical middle qualities. Verona Green Earth is a relatively warm greyish or olive green.
