Smokey quartz, also known as Smoky quartz and Cairngorm, is a variety of quartz crystal found in the Cairngorm Mountains of Scotland. It usually has a smokey yellow-brown colour, though some specimens are a grey-brown.
Like other quartz gems, it is a silicon dioxide crystal, with a small amount of ferric oxide impurity which gives it the characteristic colour.
It is used in Scottish jewellery and as a decoration on kilt pins and the handles of ceremonial knives (worn as part of the modern Scottish Highland dress along with the kilt). The largest known cairngorm crystal is a 52 pound specimen kept at Braemar Castle. |
