JN2201 Vivianite with Ludlamite
Cabeca do Cachorro, Sao Gabriel da Cachoeira, Amazonas, Brazil
24.5x 20.5x 7.0 cm
$980

A large specimen with a vivianite spray, and little ludlamite accents scattered around on the iron rich matrix.  This comes from the same locality as the ludlamites in my previous update. While the majority of the production has been vivianite,  particularly well balanced pieces haven't been nearly as common. This one does have some the surface alteration (it will look like bits of limonite film not he crystals) and splitting that virtually all of them do, though the size, position and shape of the spray set this one aside in my mind-- most of what I have seen are just densely packed, matrixless clusters, shards, and the better ones tend to be rather aimlessly oriented in vugs.  Please note: the green color comes out with strong lighting (I photographed this is a lightbox).

 It's worth noting that a comparable piece from Bolivia, the country that pretty much monopolized the output of good vivianite for the last couple decades-- would be priced at least a few thousand dollars.
