- Ilfeld, Harz, Germany
- 6 x 4 x 4 cm - Sm Cabinet
An old time classic European locality, Ilfeld, Harz Mountains, Thuringia, Germany is most famous for it's highly lustrous Manganite crystals. Thomas Moore, authored the most recent work on Ilfeld in the Mineralogical Record (v. 41, n. 6). Ilfeld is a mining district which extended over two centuries between the 1700's and 1922. The Manganite from Ilfeld has yet to be surpassed in quality to this day. Numerous examples of Manganite illustrations have been figured by Mohs and many others over the years.
This specimen shows incredible, highly reflective luster to which Ilfeld Manganites are famous for. The columnar, shiny black prismatic crystals of Manganite reach 2cm. Each crystal is terminated showing no damage except one crystal on the far side which is broken off at the base. Further, the terminations show several prismatic forms in combination with numerous parallel columns, which, I believe, classifies them as a type II crystal as described by Moore (pg. 495).
