Fixer,
This will help explain why perhaps Winspear chose Tahara's plant... it has a reputation for high recovery with VERY LOW STONE BREAKAGE....

Subject: On th subject of valuation

Apart from the comments, reportedly from diamontaires,
refering to the color as good as "Russian White"-the DeBeers
term is "Finest White":-), an important aspect of valuation,
given similar color and grade is the SHAPE of the
crystals.....The most important factor in the value of a cuttable
rough diamond is its shape. For example, a ten carat flat
macle may yield only a few carats of baguettes, but a well
shaped octahedron of ten carats may yield two well
proportioned stones of perhaps 3.5 and 1.5 carats each. Thus
two crystals of equal weight and color and imperfection grade
can have a value relationship in which one is worth at least ten
times as much as the other, on the basis of shape
alone.......you may recall pictures of the diamond recovered
from the MPV pipes.....lots of broken crystals..... the
comparatively violent emplacement process of pipes (in
comparison to dykes and sheets) leads to a much higher
proportion of broken crystals and lower average values per
carat....My question for you Will, is are you aware of the
percentage of crystal with a octahedron shape for the plus
one carat size fraction recovered from Snap Lake? I assume
it must have been high. Have you factored this into your
guestimates of the range of percentage of gem diamond one
might expect from the 6000 tonne bulk?
