Harmotome

ID: CC18794
Translucent, colourless to milky-white Harmotome crystals cover the upper surface of a naturally etched plate of Calcite matrix. From the Samson mine, 0.5 k NW of St. Andreasberg, Harz, Germany, this old silver mine worked until 1910 producing a large suite of ore minerals together with some zeolites, including the relatively rare species Harmotome. The crystals are typically about 6 mm in length, are double terminated and form a dense mat of crystals over the Calcite.
Ex. the Mineral Collection of Archduke Stephan Franz Viktor of Hungary (1817 to 1867), with a historic Archduke (Erzherzog) Stephan label incorporating his coat of arms.  This large label measures 9.9 x 8.1 cm and is complete (untrimmed) and is numbered 260/9.  A small label bearing this same number is glued beneath the specimen and a Carl Rumpff label, dated 1889, is attached to one side.  The specimen comes with one of the unique green card boxes which the Archduke had specifically made to house the specimens.
