This is a mounded, three dimensional Tsumeb Calcite specimen with internal Duftite and minor Hematite highlights that produce fantastic phantoms! The interlocking Calcite rhombs of this fascinating piece are asymmetrically zoned and all of them exhibit phantoms to some degree. Many let you look through them to a carpet of micro xls of duftite underneath for a really subtle but complex effect, visually. The interior of the crystals are dominated by scalenohedral Calcite phantom crystals in which the points have been beautifully accented by a pronounced dusting of pistachio green duftite (or perhaps it could be lightly colored Mottramite within). The cityscape-like rhombohedral overgrowths are ghostly transparent so the green phantoms are easily seen. Some select edges of the Calcite crystals are highlighted by sharply delineated white rectangular zones, making for very aesthetic crystals and a naturally artistic piece! The Calcite rhombs vary in size from 1 to 2.5 cm on edge. The thin Hematite is only visible on the Calcite crystals around the periphery from an earlier generation of Calcite. A sublime specimen from Tsumeb, an absolute classic rarely seen for sale, and thought to have come out in the 1960s era here. This is one of the better examples of this style I have seen over the years (starting in 1984 as a dedicated calcite collector myself, I always wanted one of these and never found one for sale I could afford at the time!). The best of this style is known as the "Miller Collection specimen" which is now locked away as the 6-figure pinnacle piece in a large private calcite collection. This is smaller, but not far off in quality, and is one of the better examples we have seen for sale over decades. Ex Rock Currier collection, although he had never cleaned it and we cleaned and trimmed it recently to make a balanced, beautiful specimen.
