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.

Bobcookite is a relatively new IMA mineral named after my good friend Dr. Bob Cook. It is easily observed as it is highly flourescent green and occurs as yellowish green glassy crystals with white silky Pickeringite. This is the fourth occurence, but all are in the same district. It is not found anywhere else.
