Discussing the Identification of Rough Diamonds
by Kelly Ross, A.G. (C.I.G.), Lethbridge, Alberta
The Canadian Diamond industry is in its infancy, however, the size and relative value of this industry may soon be among the largest in the world. Aside from scattered small deposits, there are no other known valuable gem deposits in Canada. The mine to market chain for diamonds has many steps including the original mining of the rough gem material. The sale of the rough gem material to large buyers. The cutting of the rough diamond into consumer material. The sale of the cut diamonds to wholesalers and then the sale of diamonds from the wholesalers to retailers. Lastly the sale of diamonds from retailers to consumer. Until recently, the diamond industry in Canada virtually existed in the last two steps of the chain. With the mining of diamonds in Canada that is changing and all the steps of mine to market chain are evolving.
In order to deal effectively with diamonds, one should be well educated in the identification and evaluation of the cut and polished diamonds. A good working knowledge of diamonds in their natural form, known as ìroughsî is very desirable. With the growth of the diamond industry in Canada this knowledge will be increasingly more important to Canadians in the gem trade.
