3" Sparkly, Pink Amethyst Geode Section - Argentina

 
This is a beautiful find out of Argentina, featuring true pink amethyst crystals from the Choique Mine. It occurs in geodic formations or cavities lined with crystals.

This geode section is 3" wide and comes with an acrylic display stand.

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.

Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
