Lamy Azurite Fountain Pen Ink Review

Lamy's line of new ink is called "Crystal Ink". In Azurite at least, it looks like it is a well deserved name. When it is poured under water, it exhibits a completely different color: copper! Being that the mineral azurite is purple blue, like the ink, and it often occurs with green malachite, like the ink's sheen, and it is associated with copper ore, like the ink's copper color--did someone at Lamy actually try to make an ink that deserves it's name? If you are aware of what causes this phenomenon, can you comment on what it is? Does anyone know if other inks are that way? I've tried a few, but I haven't found another one that does it yet.
