Also known as Cairngorm Quartz after the Cairngorm Mountains of Scotland where it was once mined, Smokey Quartz is the national gemstone of Scotland
It is believed that Smokey Quartz helps to build a strong relationship and instill peace and harmony. It is thought to transform negative energy and is reported to be effective at dealing with anger. Most Smokey Quartz coming out of the ground is not very consistent in colour and is therefore often heat-treated.
In addition to Scotland, the required gem has been discovered in Brazil, Germany, Australia, India, Madagascar and the USA. See also Quartz.
