Tarnowskie Gory Smelter, Upper Silesia, Poland. 30mm x 25mm.
Out of stock
While exactly the same chemical formula as natural Zincite, these specimens "happened" in the 1970's when the smelter chimneys roof leaked excess oxygen into the system. The smelters have been upgraded since then and while these where a hit in Tuscon for a few years they are now incresingly hard to find. This specimen is a bright red one, very similar in colour to the Rhodochrosites of N'Chwaning 1 Mine here in South Africa.
