Hey Loser. Mr McCallum did say many of the stones have the same signature its in the release . Go pack some fudge with your boyfriends.

The parcel of diamonds recovered from the two 100 tonne kimberlite samples
obtained from the NW dyke comprises 1,387 diamonds. A study of 1,291
diamonds from this parcel was undertaken by Dr. Malcolm E. McCallum, a
recognized international expert with considerable experience in this field. The
remaining 96 diamonds that were not studied in detail represent the smallest
screen-size of diamonds recovered. Because plant recovery in this small size range
is inefficient, these diamonds were considered to be unrepresentative of the size
class and were omitted from the study. Although the small size of this diamond
parcel precludes rigorous statistical treatment, Dr. McCallum considers that the
observed distribution of the physical properties is statistically relevant. The main
conclusions of his report are as follows: The various physical characteristics exhibited by the three large gem diamonds
(10.82, 8.42, and 6.04 carats) recovered from the kimberlite are completely
consistent with those observed in smaller stones from all size fractions.
There is a strong correlation of morphological characteristics between diamonds
recovered from each of the two sample sites.
The number of large stones recovered from this sample is unusual but not
unprecedented. Based on the high concentration of large diamond fragments in the
+9 and +11 size fractions, as well as evaluation of size-frequency distribution
curves, preferential breakage of larger, poorer quality stones appears likely to
have occurred either by late magmatic or induced processes.
Dr. McCallum subsequently has commented that some of the overgrowth features
present on many diamonds in this population have not been reported from other
localities in NWT and may provide a unique signature for diamond parcels from
the NW dyke at Snap Lake. Winspear notes that kimberlite of the NW dyke is
also unusual in its intrusive form and compositional characteristics of its indicator
minerals.

<They therefore were not looking for evidence in inclusions and growth planes to determine if all the stones came from the same location.>

Can you not read? See the last NR!

In other words, an independent expert has looked for evidence of different signatures and found none. Your concern is no longer an issue.....
