OCCURRENCE OF PRECIOUS STONES IN N.S.W. 241 
have been cut to weigh two carats; but the great bulk of the 
stones that might be purchased were under one carat when cut. 
As regards the quality of the stones, the mine has yielded some 
gems that realised as high as £10 per carat; of course the ordinary 
run of the stones realise nothing like this figure, being rather 
light in colour, approaching rather to aquamarine than emerald. 
The proprietors of the mine state that 40,000 carats of emerald 
were yielded in eighteen months. Although the mine is not 
working at the present time, there is no doubt that a large 
quantity of emerald is still available. It may be noted here that 
this is the only occurrence of emerald in Australia in a true fissure- 
lode, associated with the minerals already enumerated. The 
Siberian emeralds as is well known, are found in mica-schist. 
But emeralds are known in pegmatite lodes some five feet wide 
near Bakersville, Mitchell County, North Carolina.’ 
Although the above mentioned is the only known instance of 
emerald occurring in a matrix in this Colony, beryl has frequently 
been noted in situ. The greenish coloured beryls mentioned by 
Professor Liversidge from the Shoalhaven River could not have 
travelled far from their matrices. Some eight years ago, beryl of 
Sood “quality was found abundantly in the Elsmore Tin Mines. 
But the stretch of granite country between Emmaville and Tenter- 
field, known as the Mole tableland, is the most prolific locality 
for beryl in this country. The detrital matter from this granite 
almost invariably contains beryl. As the same detrital material 
is often washed for the tinstone it contains, bery] is a well known 
and common mineral amongst the tin mines of that part of New 
England. Some magnificent crystals have been found, some of 
the best of which have, to the writer’s knowledge, been acquired 
by foreign museums. Beryl has undoubtedly been found at Ophir 
near Orange. Good hexagonal crystals of this gem are found in
