Found this paper on the process of identifying rough diamond. A good read...

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 roughs 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.

In this area of the world it is known to have a high mineral concentration and so the separation of materials is paramount. We have such fine grit in the cons one can easily find here that it make it rather hard to separate from the pay dirt. Is there a relation of hardness to Ph and specific gravity of 3.52 of the water you mention? How does one produce the right specific gravity to suspend the diamond particles? I wonder if gold in the same cons will fall out or rise? Does graphite float in the specific gravity of this type water? It would make separation a truly wonderful experience for the average prospector.  Wink Wondering as well if there is an easy way to control or alter the specific gravity for ones needs?
If you cant answer these questions could you please pass this on to someone who may know and give us a good incite
 Many thanks Pan

Hi, Dose any one know if a Geochemical Meter would give you a indication that there is carbon in the water sample or in the soil. Had a placer claim on Maus creek and had a fellow phone me asking if I had ever found any . Not wanting to be too dumb to the fact that I had only seen one sticking out of a block of stone and that was at Butte MT. ( Ming Mus em ). Hell we were having enough trouble finding Gold.
         Take care , Pasty

Geochem meter would not be able to tell you what the chemistry is that is changing the conductivity - I am assumping you are referring to the Action Mining Geochem Meter.
Carbon would not really be a help in diamond search I think. Too many other carbon sources and easy to take them into solution.

Here is another useful PDF with images. Although it is based on material found in Colorado and Wyoming, it may still be relevant to Canadian Diamonds.

Dan Hausel and I both take folks on field trips. The state line district in CO/WY may well be the largest field of kimberlite and lamporite on the continent.
Basicly the diamonds look like a wadded up piece of chewing gum wrapper. They come in many colors, yellow and chocolate, and regular ol white around here.
