THe CHaLcEeDony of Jewellers is a pale variety, it is the 
“patra dura ’’which the Italians use for the stone cameos. 
CHRYSOPRASE.—Of rich apple green colour, is found 
in the Logan and Yaamba districts, also about Springsure. 
This stone, which until recently, was only procured from 
one locality in Bohemia, is said to ensure good luck, and 
was formerly used for green and white cameos, it is far 
superior in richness and colour to the New Zealand green- 
stone. 
It owes its peculiar soft hue to nickel oxide. 
AmETHYST.—Crystals of amethyst are found in many 
districts in this State, including Stanthorpe, Kilkivan, 
the Burnett, Bowen, Anakie and Herberton; they are 
simply quartz crystals coloured purple; they are very 
beautiful, and those of good rich colour, clear and free 
of flaws, have considerable value. 
The amethyst is another of the ecclesiastical gem 
stones, and is even now worn by nearly all bishops. 
In ancient times it was valued on account of its 
mystical properties and as an antidote to drunkeness. 
THE CAIRNGORM is another of the varieties of quartz 
crystal, it ranges from yellow to deep brown, and is found 
practically throughout the State. 
JASPER.—Is found on the Gympie goldfield, Stan- 
thorpe, Oxley, and other districts. 
Moss Acate.—Found on the Burnett Water-shed, 
at Stanthorpe, and many other places; in appearance 
it is as though moss had been imprisoned in the clear stone. 
Morion.—A variety of banded smoky quartz crystal ; 
is very handsome, and found on many of our gold and tin 
fields. 
Rose Quartz.— Quartz of rosy hue is frequently found 
in the State. 
SAGENITE.—Sagenitic quartz, sometimes called grass 
stone by the miners on account of its appearance, which 
is peculiar owing to the inclusion of asbestos fibres in the 
crystals ; on some of the fields these grass-stones have con- 
siderable local value. 
This stone was formerly known as the Venus’ hair 
stone. and also as Cupid’s arrows, Marmor’s hair, etc.
