Lapis Lazuxti.—Has been found near Herberton. It 
will be well-known as the chief constituent of the genuine 
ultramarine. once so much used by artists. 
MoonstonE.— The moonstone is invariably associated 
in the minds of Australians with Ceylon, as the whole of 
the moonstones sent here are from Ceylon. 
Moonstones have been found in Queensland, near 
Nanango. Moonstones are the milky and _ transparent 
varieties of several species of felspar, remarkable for the 
pearly reflection of light. They are generally looked upon 
as lucky stones by the natives of India. 
The hardess is about 6, specific gravity about 2.6; 
composition is silicates of alumina with silicates of alkali 
and silicates of lime. 
The colours of gem stones in Queensland are quite 
a revelation to the popular mind, and in order to show the 
wonderful range of colour which our gem stones possess, 
I attach the following list of stones arranged under different 
colour headings. By these it will be seen that the 
sapphire, which popularly is a blue stone, is in this State 
found of every hue of blue, green, yellow and orange. 
I also exhibit a colour star diagram of Queensland 
gems, which proves that practically every colour and every 
shade and tone of colour is represented by the gems of 
this State.
