Quartz
Quartz is the second most common mineral in the Earth's crust and can be found nearly everywhere in many different variations.
Here in Germany on the banks of the river Rhine, we mostly find milky quartz.
The white colour of the milky quartz is caused by inclusions of gas or fluid and it is the most common variety of quartz.
But even those common milky quartz pieces can show astonishingly beautiful structures and colour variations and often contain parts that are crystal clear.
