A bit more info from here:


Cairngorm is a variety of quartz crystal originally 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 sgian dubhs (more widely known by the anglicised version skean dhu). The largest known cairngorm crystal is a 52-pound (23.6-kilogram) specimen kept at Braemar Castle.

Cairngorm (the gemstone)

I realise that this thread is now rather old (2006), but thought that forum members might be interested to know that I have recently completed a project to research the minerals and gemstones of the Cairngorms, and the associated social history of the people who once sought them in the harsh mountain environment back in the 1700s and 1800s.

The results have just been published as a book, illustrated with lots of colour photos of the minerals, gemstones, jewellery and landscape. I have set up a website where you can learn more and also watch a video of the fabulous Cairngorms scenery British Mineralogy | Welcome to the home of British Mineralogy

Hope you find it of interest!
