Let's start simple
What is smoky quartz?
Smoky quartz is ordinary quartz that has been exposed to natural radiation in the earth, which, together with traces of aluminium, turns it brown to grey. It grows as six-sided points and clusters like clear quartz. It is Scotland's national gem, where it is called cairngorm. Some smoky quartz on the market is clear quartz irradiated in a lab.
Its earthy colour links it with grounding, steadiness and quietly letting go.
"Smoky quartz is the exhale after a long day."
