CAIRN GORUM CRYSTALS. 49 
Europe from India and Ceylon. These, although they 
are with truth denominated oriental, must be carefully 
distinguished from the true oriental amethyst (55), 
which is a much more valuable gem. The amethysts 
next in esteem are found in Brazil, and are procured 
in the mining districts of that country. Siberia, and 
various countries in Europe, especially Germany and 
Spain, also furnish very beautiful amethysts; and in- 
ferior stones of this description are even found in the 
mountainous districts of some parts both of Scotland 
and Ireland. 
80. FALSE RUBY is a crystal of red colour, and found 
in Bohemia, Silesia, and Barbary. 
81. FALSE, or WATER SAPPHIRE is a dine crystal, 
which does not differ much in appearance from the 
true sapphire, but is considerably less hard. This 
kind is found in Bohemia, Silesia, and some parts of 
Switzerland, but it is not so valuable as the last. 
82. FALSE EMERALD is a green variety of crystal, the 
scarcest and most valuable of all the coloured kinds. 
It is chiefly found in Saxony and Dauphiny. 
83. YELLOW, or TOPAZINE CRYSTAL i$ a stone of 
wine-yellow colour. It is found in Brazil and Bohemia, 
but has no other alliance with the true topaz than its 
colour. 
84. CAIRN GORUM CRYSTALS are obtained in va- 
rious parts of Scotland, but particularly from a mountain 
of that name in the county of Aberdeen. They are 
usually of smoky yellotv or brown colour, and are, at this 
time, so much in request for ornamental articles of 
dress, that several lapidaries have been induced to settle 
in Aberdeen, who are constantly employed in cutting 
them for seals, rings, necklaces, brooches, and other 
trinkets. When these crystals are of deep and good 
colour, they are nearly as estimable as topazes ; and, 
if clear and large, they are sold at a high rate. The
