This large and dense aggregate of murky, camoflage green Pyromorphite is labelled as from Bad Ems District in Rhineland-Palatinate, Germany, but is reminiscent of the colour and form of Pyromorphite from the famous Mercur mine at Bad Ems. With very chunky (1 cm) hexagonal crystals as broad as they are wide, it is a very noticeable piece and the formation of black-lined (? manganese oxides) cavities with swirling layers of Pyromorphite adds considerably to its character. There is some damage to the more exposed larger crystals, but within cavities the crystals are in superb condition and it is so rare to see this particular colour and form of Pyromorphite in specimens larger than miniature in size. It is from the superb collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
