- Toenail, 3.1 x 2.3 x 2.3 cm
- Manganese deposit, Ilfeld, Nordhausen, Harz Mts, Thuringia, Germany
A BEAUTIFUL and AESTHETIC cluster of diverging, brilliant, black manganite crystals from Ilfeld, Germany. This is NOT just a "black rock" by any means. It displays very dramatically and impressively. These old pieces came out in about 1886-1888 (per Bancroft's book) .
