Childrenite on Quartz monoclinic and take my word for

and take my word for it

"sword"-shaped crystals of Vivianite with white bladed Barite and minor metamorphosed Sandstone

If you’re a collector of Cassiterites or Bolivian minerals

Childrenite on Quartz monoclinic and take my word forSome of the best crystallized phosphates from Bolivia are found at this locality. Childrenite is a relatively rare, hydrated iron aluminum phosphate and some of the better and more unique specimens of this mineral come from Llallagua. There are only a few localities in the world where this mineral is found. This specimen features several excellent, rare, sparkling, brownish color spherical aggregates (comprised of dozens of triangular bladed crystals)
