You are wrong. I called TSL (306) 931-1033 and they do not do testing on core samples for diamonds. He said the SRC (306) 933-6932 out of Saskatoon does and gave me the gentleman who is in charge of testing for diamonds....whom I will call WHEN THEY REOPEN JANUARY 5TH....they are closed down for the holidays until monday the person told me at TSL like most Labs are. So Walter was right and no wonder you said, "Don't worry about it." This give you less credibility in my eyes. I have been wondering on the last few posts of your's as too whether they hold any water since I could not verify with my intense research nor the office knowing anything. I wish you would have your information more secure and in depth before you post.
