Please see photos for beauty, color and condition. This has been in storage for many decades. From an estate sale. Originally part of a larger specimen sample collection. The box is labeled as “Psilomelane” and I have concluded this sample could be identified as Romanechite based on images and information on the internet. If this is incorrect, please let me know and I will revise listing. From Mineals.net. “Psilomelane describes barium manganese hydroxides that do not form invisible crystals. Originally recognized as an individual mineral species, Psilomelane was discredited by the IMA in 1982. However, the name is still in use today, describing manganese hydroxides such as Romanechite and Hollandite that are not specifically identified and sometimes even admixed together" See my other listings for more from this old stock collection.
