I appreciate the replies from all parties given in the past year. I
read every one and make notes.
The answer to my main question about “crystallography profiles” (for
want of a better expression) which are as affordable as conventional
assays, so far the answer is NO. The best I can find is at Acme Lab
in Vancouver (Googleable) the following under “Geochemical Whole
Rock Major and Trace Element Analysis”
Acme will work with .1 gram samples and give back a profile of 11
mineral oxides.with lower limits usually of .01% and upper limits of
100%. This plus a few others which includes C (organic + inorganic I
assume) in a 20 parameter profile for an affordable $26.70. So that
is Group 4A, “Whole Rock by ICP”.
Now 4B (Total Trace Elements by ICP-MS) requires .6 grams but it
yields a profile of 45 elements including Be.
I just gathered 500 lbs of samples and guestimate they contain about
1,000 tiny “intensely” green crystals, some quite transparent and
some more opaque. I’ve seen a lot of local jade and crysoprase and
neither is even close in being as intensely green. The largest is
about 1/10 mm. With a lot of painstaking work, I could isolate these
1,000 crystals with some of the matrix still clinging. So let’s say
I end up with 2 grams of which 90% is matrix. Acme can assay it as
above. What use is that Correct me if any of the
following is in error:
If I have green sapphire then I expect high Aluminum Oxide.
If I have green emerald then I expect a high Be assay.
With all due respect for those who have posted that dust-sized gems
are of no value, I disagree and IMO their error is because they are
gemologists but not prospectors. If I end up with proof that these
little gems are either sapphire or emerald then I expect the mineral
properties for this entire end of the Fraser Valley will be claimed
by the big mining companies. Likewise for diamonds.
But I do not think the Acme assays on their own are very close to
complete proof. So let’s say I follow up the Acme assays with sending
samples to a jeweller like yourself for RI and other tests like SG
and solubility and do get that complete proof. But first I would have
to know the tests.
What I have not been able to get a direct answer on is the size of
INDIVIDUAL microminerals which can be determined by a skilled
If I send you one gem in the “micro” range, ie one microgram and one
micrometre can you determine if it is diamond, sapphire or emerald?
If I send you one gem in the “nano” range 1,000 times smaller can
you do the same?
Granted you are not going to see these gems at Buckingham Palace.
You only going to see them in the crown jewels of Lilliput or maybe
the British Museum in London which I quite enjoyed, including the
entire oil rig from early days of oil mining. Remember Daniel Day
Lewis who won an Oscar for his performance in “There Will Be Blood”?
When he switches from silver prospecting to oil he is first
laboriously hauling buckets of goop to a storage pond. This is a
digression except that quick and cheap methodology which opens BC to
microgem prospecting and mining on a big scale might well get a
display in the British Museum.
From the standpoint of marketing, imagine a display in a downtown
Vancouver jewelry store with a projector and good resolution
equipment diplaying local emerald or sapphire microgems from a
display case onto a screen. Outside on the sidewalk there is my bad
twin and bag lady Penelope Dirtbag from the Vancouver Stock Exchange
with an organ grinder and a monkey selling shares in the Dirtbag
Mining Company. “Brother Can You Spare A Billion”? Us Dirtbags like
to think big.
If I find gold dust on the bar where River A meets River B that
points to gold upstream. That is its value. And it IS value even if
we do not know which stream at first.
Now as for my tiny micromineral crystals which may be diamond, I
have similar ratios of samples to material for assay. Acme assays can
determine organic C and inorganic C. But which is graphite? Is
diamond the only inorganic C?
PS - In high school my prospecting led to discovery of two species
of fossilized shell fish in sandstone of the Ottawa Valley. My HS chem
teacher said, Quartz is not soluble. But I had the 2 mm and smaller
quartz crystals in the shell fish to prove otherwise. I never told
her this. Her husband was an eminent PhD geologist. Maybe in those
days (50s) the theory of quartz solubility was as suspect as the
theory of plate tectonics or calaclysms in species development or
deep-dwelling microbes or the theory that some mantle rocks can end
up as huge surface formations, eg in Newfoundland. When did the
theory of micro-organism formation for microgold gain acceptance?
Even the QUESTIONS which challenge science dogmas are ridiculed at
first. Google on Yukon emeralds and read a team of eminent earth
scientists calling their etiology an “enigma”.
My HS chem teacher called water “THE UNIVERSAL SOLVENT”.
How soluble are diamond microcrystals?
Are there any micro-organisms which may ingest them, transport them
and concentrate them as is done for gold and platinum by tiny
Us Dirtbags like to think small.
