rial crown. It is well adapted for seal engraving, and on it 
coats of arms, crests, cyphers, &c. appear to great advantage. 
There are said to be in many of the European museums, some 
very fine cameos and intaglios, which have been cut on this 
stone. It forms a pretty connecting link between the pink topaz 
and the deep rich maroon of the carbuncle. Sunlight and heat 
are very injurious to its beauty, by causing it to fade, appa- 
rently extracting its color, and diminishing its lustre, as ex- 
posure for any ‘length of time in’ a window has fully proved. 
This stone too is mentioned in -and was appointed in = 
Exodus for the ninth stone or third in the thi v of the phot 
priest’s breastplate. It is also freq ) 
up of posy or acrostic jewelry, as <aenee In England; when _. 
making a present of a ring or brooch, they have © a delicate way 
of expressing a sentiment, that of arranging the stones in setting,

This together with some word or name, is made up into a 
half-hoop finger ring. When a sentence is desired, the stones 
are either set entirely round the finger, or a large centre stone or 
glass for the hair, or for a breast pin. 
The imitations of this stone are so perfect as readily to deceive ; 
but upon close examination small globules of confined air can be 
readily perceived; the best method for the unpractised is to have 
recourse to the file; this is at all times the only unerring test, all 
imitations of gems being scratched by that instrument. 
3. Cairn-gorm, (Citrine, Yellow Crystal or Quartz, Bohe- 
mian Topaz, §c.) This is one of the beautiful inferior gems, 
passing insensibly from a pale straw to a bright yellow and deep 
orange color, and is held in much esteem on account perhaps of 
its close resemblance to the topaz; it however possesses a suffi- 
cient individuality whereby one of small experience in these mat- 
ters may be able to distinguish the difference. It rarely or never 
exhibits the delicate though rich tinge of fawn or buff, which is 
the general characteristic of this gem. It is very transparent, and 
in constant demand for seals, cane tops, ear rings, breast pins, finger
