An old, well formed and crystallized Malachite from Rudebanya ex Charles Noll collection. The Malachite is quite lustrous and contrasts with the gossan matrix, but this is nearly all Malachite. This is also a well formed and fine Primary Malachite, not a pseudomorph. The luster is bright and satin like with clustered groups of prismatic crystals in spherical arrangements. In excellent condition, we do not know the vintage of this piece but the style is only seen in very old collections, and the locality has been mined since the copper age, it is one of the oldest mineral sites in Europe. Impossible to find specimens of this caliber today.
