This flat features Malachite and Hematite crystals from the Kyffhäuser region in Thuringia, Germany. The specimens show a wide range of structures and color tones: from intense emerald to blue-green malachite coatings and fine-grained aggregates to dark brown and metallic-black hematite zones. The characteristic green malachite contrasts strongly with the reddish-brown host rock, giving each piece a distinctive geological character. Several specimens display clearly recognizable microcrystalline textures typical for the oxidized copper and iron mineralisation of this classic Thuringian locality.
Geology & Origin
The Kyffhäuser region is a historic mining area whose mineral diversity largely originates from the oxidation zones of former copper- and iron-bearing veins. Malachite forms there through the weathering of copper-rich primary minerals within carbonate and silicate rocks. Hematite develops in the same environments through the oxidation of iron-bearing phases. The combination of both minerals – vivid green and metallic dark – is characteristic of the area and reflects the complex geochemical processes occurring during the transition from sulfide to oxidized conditions. This flat presents these typical mineral associations in a broad and visually appealing selection.
