How much are "specks" of gold worth?, Trying to put a dollar value on a "speck" of gold Options

How much are specks of gold worth? I wondered, I googled to no avail, and so I'v tried to figure it out myself. "Specks" is a fairly loose term so I mean the stuff too small to pick up with a finger or tweezers, what some call "micron gold" or "fine gold", often only a sniffer bottle can pick up. Between 500 microns (.5 mm, or thick fingernail) and 30 microns(barely visible).

A cubic 1.6 cm troy ounce of pure gold is about $1200, with impurities reduce that about 25% of that value or about $900 for "nuggets", and per cubic centimeter of "nugget" which is seldom square, rather usually rounded or in flakes which would be even less, or would come out to about $200 per cubic centimeter. So 1 cubic millimeter of gold nugget would be worth about 20 cents on average, since it takes 1 thousand cubic millimeters to make a cubic centimeter, and that's assuming the nuggets are round, flat flakes would be worth half that or less. It takes 1 billion cubic microns to make 1 cubic millimeter, and 30 microns is the smallest thing our eyes can detect, a human hair is about 80 microns in width. So "micron gold" specks might fall between 30-500 microns or maybe 250 microns on average(thin fingernail thickness), also depending on how round or flat they are shaped. So it would take somewhere between 8 to 80 gold specks to make 20 cents worth of gold. A piece of gold that's just barely visible to the human eye is worth about 1/1000th of a penny. If all my numbers are right. Does this seem right?
There is more than one "worth" in a speck of gold though beyond dollar signs, fun per hour, indicators of increasing or decreasing gold concentrations, put them in crystal ball with a little miniature gold miner inside and watch them float around, idk what else?

Weight is the easiest way to see what you have with all the possible shapes and sizes but it doesn't count for impurities.

Wow, you've put a lot of thought in to this. Nothing readily available to actually weigh it, so your calculation is as good a guess as you're gonna get.
