Babanekite is the copper member of the Vivianite group. It's fun to look at these minerals as they all look the same just different colors. Babanekite was described in 2012. The crystals on this specimen are less than 0.3mm and are pink, not green as you would think. It probably contains small amounts of cobalt. From Dr. Hyrsl Jaroslav's stock.
