Locality: Ilfeld, Harztor, Nordhausen District, Thuringia, Germany. Mineral: Manganite. A classic manganite from this best-of-species locality. Hopefully it is conveyed well enough in the video. An excellent example in this size range, in superb condition all around.
Material: Permineralized fossil wood with druzy mineralization. This is a substantial display piece with well-preserved wood grain, deep natural ridges and small druzy quartz crystals that sparkle across the surface under direct light.
