Vivianite

VivianiteThis specimen was collected in 2000, when Huanuni had a short, but prosperous boom of specimens. I personally obtained this piece at the mine on one of my first trips to Bolivia. I kept it as a memento of those early years visiting Bolivia, but its time for it to find a new home. The piece features a very sharp, GEM quality, rather lustrous, rich emerald green, sword shaped crystal with a beautiful termination on Pyrite matrix. The accompanying

very well-crystallized

but to find non-pseudomorphic native Copper is rather rare

Specimen # AMBER51707

The “cogwheel” is essentially undamaged

The upper right corner is contacted

and to the best of my knowledge

Specimen # BOL711B277

black to very dark golden colored cyclic twinned crystal group which is associated with small acicular crystals of rarely seen greenish-brown Tourmaline

From the impressive find of 2004

it is truly only known from a handful of localities in well-crystallized display specimens

This species belongs to the only group of minerals that forms in naturally "round" or "cylindrical" shaped crystals

rarity and the fact that it is literally one in several thousand
