One of my best roweite matrix specimens, it shows perfect flower like structures of the orange roweite found only around 2016. Roweite is a very rare borate mineral that before this find had never been found in crystals, anywhere, Also on close inspection of this piece you will find olshanskyite, calcite, andradite, magnetite, white cahnite and a few white johnbaumite crystals.
