Natural Crystal - Clear quartz
Clear quartz crystals have an incredibly long history of use in all sorts of fields.
They are one of the most famous crystals in the world, and have been significant to cultures on every continent, as well as being the base for many other crystals, including extremely precious ones like amethyst.
Quartz crystals are made of silicone and oxygen, but frequently contain other trace minerals and metals, which can give them a wide variety of colours. The beautiful clear quartz crystal is by far the most famous, but they come in every colour of the rainbow, including rose and smoky quartz, which also play major roles in many traditions surrounding crystology.Note:
