An incredibly rare specimen of turquoise-sky-blue Willemite pseudomorphing after a group of vertically orientated Azurite crystals. Such a pseudomorph is hardly ever seen from Tsumeb and in this specimen, the Willemite crystals stand about 2.7 cm tall above a bed of blue and white Willemite which forms the base. The Willemite is quite heavily coated with cream and white micro-crystals of Calcite which give this miniature specimen an overall creamy-tan colour with patches of turquoise blue breaking through. Adding to the aesthetic are many pale lemon acicular Mimetite crystals to a few millimetres in length. An almost one-off pseudomorph of Willemite after Azurite from Tsumeb.

Regional guide
Willemite from Tsumeb, Namibia
Tsumeb willemite is the zinc silicate for collectors who usually think of willemite as a fluorescent-mineral classic from Franklin, New Jersey, and then discover that Tsumeb rewrote the aesthetic rules. Here, Zn2SiO4 appears not as massive ore but as glassy to sparkling crystal groups, botryoidal crusts, radiating sprays, delicate acicular “lawns,” and rare individual hexagonal prisms. The colors are equally un-Franklin-like: white, gray, yellow, green, blue-green, turquoise-blue, pale blue, reddish brown, and the much-loved champagne to honey tones. The best pieces have a crisp, jewel-like presence in daylight, often on white calcite or dolomite, with the color contrast that Tsumeb collectors prize.
