Some of the brown varieties found at Lachute, Calumet Island, 

 and other places, might contribute small gems. 



Zircon is of frequent occurrence in Ontario and Quebec, and 

 constitutes such gems as the Hyacinth, Jacinth, and the Jargoon. The 

 latter variety has not been met with in Canada. It comes principally 

 from Ceylon, it is perfectly transparent and almost colourless, and 

 on account of its peculiar smoky hue is sometimes passed off for a 

 Diamond. At the Colonial and Indian Exhibition in London speci- 

 mens were shewn under the name of Ceylon or Matara Diamonds. 



In the Counties of Renfrew, in Ontario, and Ottawa, in Quebec, 

 magnificent crystals of the brownish-red variety have been found from 

 time to time, but with the exception of a few very small hyacinth 

 coloured crystals from Sebastopol, not fit for cutting. 



Independent of the cutting qualities of this mineral, and partly on 

 account ot its crystalographic forms, single and twinned, it has been 

 greatly sought after by mineralogists. Forty dollars has been paid for 

 a single crystal from the Township of Brudenell. Small crystals of an 

 inch and under have no value, but large and well-defined crystals 

 command a good price. 



Spinel is thought to have been included under Carbuncle by the 

 ancients, and even to-day it is often sold in Ceylon for the Ruby. This 

 mineral is known to jewellers and others under various names, such as 

 Spinel Ruby, when of shades of red ; Balais Ruby, when pale red or 

 rose-pink ; Almandine Ruby, when red bordering on shades of blue ; 

 Sapphirine, when blue, and Pleonast, when black. 



In the Township of ^^'akefield large cubical crystals of a dark 

 green and purplish colour occur in a vein cf Calcite, and at times 

 afford small dark green and blue transparent gems. In the same 

 neighbourhood octahedral and cubical crystals of pink Spinel (Balais 

 Ruby) occur sparingly, sometimes three-quarters of an inch across, and 

 although marred with numerous cleavages, afford small pieces from 

 which fair transparent gems may be cut. The blue variety is said to 

 occur in limestone in the Seigniory of Daillebout. Black octahedral 

 crystals, often grouped together, are mentioned in the Geology of 

 Canada as occurring in Burgess in flesh-red limestone.
