In answer to your question if the sample was salted with foreign diamonds it would not be obvious to the average Canadian lab worker. the deposits are not clearly typed and diamonds vary so much it is very hard to type them anyway without expensive inclusion and irradiation tests.

As I pointed out it could even be drill bit diamonds that go up to 5 carats. Southernera had a great run thinking they had coloured fancies a few years ago and no less lab than Lakefield research had detected these deep yellow diamonds, which were fairly large. They turned out to be diamonds from the drill bit. Contrary to what some may think, drill bit diamonds these days are not carbonado but clear yellow or red artificial diamonds and are exceptionally high quality with no inclusions and are made a great deal in Russia. Remember these went to a brand new test facility and their experience is quite green.
