Item Description

Ettringite is one of the signature species from the great N'Chwaning Mines. Like Sturmanite, it is so recognizable with its yellow color, as well as its form. Here, the crystals are a very soft, pastel-yellow with a slightly frosted luster. The tapered form is attractive, and it is a habit that you often see. The largest crystal is an impressive 3.7 cm, and the crossed-sword architecture, on matrix!, is extremely aesthetic. From a well known pocket of the mid-2000s years, and Previously in the private collection of Uli & Anka Baumann (who were local Namibian collectors). From our special collection sale, direct to auction, of choice material from the collection of Richard Rossi, East Coast collector and Mineralogical Record Fellow.
