![]() ![]() The most effective way of establishing the presence of a genuine Cairngorm crystal within a specific piece of Scottish Pebble Jewellery is to gain knowledge of where the other materials (agates) in the specific piece originated, since agates are fairly location specific in Scotland.Īlthough not completely definitive, it is a way to discover if the crystal (usually at the center of the piece) is of genuine Scottish origin. Prior to all this, all quartz material including smokey quartz and rock crystal was described simply as ‘crystal’. It is rare to see clear rock crystal and most of it seems to have been mined from the east side of Loch Aven in the Grampian range of mountains in Scotland. The central crystal in the center of this brooch is clear rock crystal. These three descriptions are thought to be relatively recently adopted and only came into widespread use in the early part of the 19 th century. These three are widely found through the Grampian and Cairngorm granites. Within the jewellery trade, the most commonly occurring colours are described thus Light yellow are described as citrine, golden to darker brown are known as ‘Cairngorm’ and the darkest stones are known as ‘morion’. Scottish quartz comprises crystals varying from completely colourless through light yellows and darker browns, to almost black and in some very rare cases, red. ![]() Although this material can be found in other places in the world, it was in Scotland that Cairngorm collection and use in Scottish Pebble Jewellery was generally first associated. It is in these fissures that quartz crystals grew. When the granite was originally formed, masses from volcanic magma included material known as pegmatite which enclosed many gas cavities. ‘Cairngorm’ or smoky quartz is a crystalline material produced within granite rock, of which the Cairngorm Mountains in Scotland (4 miles high) is a prime example.
