“This is the richest, most deeply-colored example of this old material I have sene on the market. It has almost glistening lustre, very rarer for the locality. The botryoidal growth is thick, and rolling. It is obviously a very old specimen just from the label, but it most certainly was mined even earlier (certainly prior to WWII and perhaps even early 1900s or later 1800s). 9.1 x 8.1 x 2.4 cm
