This specimen, from a specific find by a local field collector between 2008 and 2011 in a mineral locality that has remained little known until now, shows a group of Quartz crystals, one of them clearly dominant, elongated, with an extraordinarily flattened habit and with Japan-law twinning distinct on the terminations that are shiny, between transparent and translucent and with reddish tones in some areas due to the presence of oxide inclusions.
