2.4" Pink Amethyst Geode Half With Grey Calcite - Argentina

This is a half of a pink amethyst geode from the Choyique Mine in Argentina. There is grey calcite crystals growing on top of the pink amethyst.

The material has been analyzed at the California Institute of Technology and was described as "purplish pink amethystine quartz additionally coloured by microscopic hematite particles". They are not rose quartz or pink quartz as classically defined".

So, it's formed by the same processes that give amethyst its purple color, but by definition amethyst is purple not pink. So, we are left with a conundrum of what to call it, but since the majority of people seem to be calling it "pink amethyst" we will stick with that label.
