gold dust 22 carats pure?
146759
Real (placer) gold dust is usually very pure, 18-22 carats. Dust which is filings from jewelry can be whatever alloy the gold was cut from, could be as low as 9 carat. Under a microscope, the placer will have rounded edges and the filings sharper ones.

Here are some questions that will help you:\n\nFirstly, are they natural or synthetic?  \nSome synthetics can look amazingly similar to heat-treated naturals.  \n\nIf they are synthetic, what kind of synthetics are they? Flame-fusion? Flux-grown? Flame-fusion synthetics can be had for a few cents a piece.  Some flux-grown synthetics cost over a $100/ct.\n\nIf they are natural, you'll need to judge their quality:\n\nColor - Is the color saturated? Is the tone balanced? Do they show undesirable brown modifiers? \n\nClarity - Are there inclusions? How distracting are they? Where are they located? Do they improve or adversely effect the aesthetics of the stones?  Do they affect durability? \n \nCut - Are the stones faceted or cabachon-cut? Are they transparent, translucent or opaque?  What shapes are they?\nAre they cut well? ie balanced & symmetrical, good length-width ratio, good polish and finish.  There is a premium for matched pairs and lots.\n\nCarat - 13 rubies totalling 50 carats makes each piece about 3.85cts.  Hmmm...that's considered large for rubies.  \nFine stones above 3 carats are considered rare.  Commercial & utility quality stones can be hundreds of carats in size and still not be very valuable.\n\nOrigin - Where were they mined? There is a premium for Burmese stones, especially from Mogok.\n\n------------------------------------------ \n\nBased on the information you have provided, it is not possible to accurately say what they are worth.  You could have a jeweller look at them, but it's probably better to send them to a professional colored stone appraiser.  \n\nAs a very rough estimate, here are some price ranges for faceted rubies in the 3ct range (in Bangkok): [Commercial/Good/Fine]\nRuby [25-300/300-1000/1000-6000]\nPink Sapphire (low saturation rubies) [50+/100-250/250-1500]\n\nBTW, 99% of all rubies available in the market are heat-treated.  A premium is put on stones that are not heated but only if they are of fine quality material.  All other things equal, washed out stones that have not been heat treated are never worth more than heated material with good color.

a 1 carat, D colour (the whitest), VVS2 (very very small inclusions 2, the 3rd best clarity after IF and VVS1), round, perfectly cut diamond, will be about 10-11'000 dollars\n\nbelow about 0.5 carat, the diamond will start to be a bit small for one to notice the clarity differences that much, or the colour differences by the way.\n\nwhich is why most jewellers will tend to offer slightly lower qualities on smaller diamonds, say not better than G (which is still quite white by the way), and no clearer than VS1 or VS2\n\nif you look around a bit, you should find one such 0.25 carat fairly white and fairly pure diamond for around 350-400 dollars.\n\nfor a piercing this may be enough.  for jewelry this is on the low-end, especially for an earring for a woman other than teenager (of course, even so the pair of earstuds, total weight 0.5 carat, would already set you back 800-900 dollars - the mount would typically be given away by the seller because it costs so little, relative).  for a ring this is too small, unless it is for a teenager.\n\nin general given that it is pretty much impossible for a non-professional to tell the difference between, say, D or F (or even G), or beween, say, IF and, say, VS1, either go to a reputable place (retailer such as Kays, online retailer such as diamondstudsonly.com), or else avoid the whiter colours and higher clarities if you cannot trust the vendor 200pc.\n\nhope this helps

Yes. But it's too soft to really make anything out of, hence the 18 or 10kt.\n\nIf an item is 24 karats, that means the item is 24 parts out of 24 parts, 100% pure. When it is 18 karat it is 18 parts pure gold and 6 parts some other metal used for strength, 75% pure. To calculate purity simply divide the stated karat weight by 24. For example 12 karat equals 12/24, which equals to 50% pure.

24k is a type of gold if u had a neckless it would not be as strong then say 10k 14k 18k

2 words come to mind.........GOLD and DUST!\nGood luck anyway!

That's about to change! The cost to manufacture synthetic diamonds is continually going down to the point now where the diamond mining companies are getting worried, especially since the "imitation" diamonds are more perfect than the real thing!\n\nBut we can't say the same thing about gold. Nobody knows how to make gold yet and it's currently over $600 an ounce and going higher.

Mostly, this is a bit of poetic license by the author of the song.\n\nHowever, it is founded in how you go about refining gold ore.\n\nWhen you're refining or working gold, the more pure the gold, the more desirable.  This is expressed in the karet figure - 10k, 18k, 24k, for instance.  \n\nSo, presumably, if it is God refining the gold, it will be as pure as it possibly can be, and therefore of the highest value.

White Gold\nWhite gold is an alloy of gold and some white metals such as silver and palladium. White gold can be 18ct, 14ct, 9ct or any karat. For example, 18ct yellow gold is made by mixing 75% gold (750 parts per thousand) with 25% (250 parts per thousand) other metals such as copper and zinc. 18ct white gold is made by mixing 75%Traditionally nickel was used in white gold, however, nickel is no longer used in most white gold made today as nickel can cause reactions with some people. We do not use nickel in our white gold gold with 25% other metals such as silver and palladium. So the amount of gold is the same but the alloy is different.\nWhen white gold rings are new they are coated with another white metal called Rhodium. Rhodium is a metal very similar to platinum and Rhodium shares many of the properties of platinum including its white color.\n\nPlatinum\nPlatinum is a white metal, but unlike gold it is used in jewellery in almost its pure form (approximately 95% pure). Platinum is extremely long wearing and is very white, so it does not need to be Rhodium plated like white gold. \nPlatinum is very dense (heavy), so a platinum ring will feel heavier than an 18ct gold ring. \nPlatinum is, however, very expensive. A platinum ring will be approximately twice the price of an 18ct white gold ring (excluding gemstone costs).

It's important to pay close attention to the metal that the earrings are made of, and that they be very clean (isopropyl alcohol) when they go in, and that they not be left in more than 24 hours without cleaning again.\n\nMost people find 14 ct. or higher gold to be the least irritating metal.  Of course, these earrings can be expensive.  Hypo allergenic studs should be good, but I think there's a lot of variation and don't know precisely what that means regarding each particular earring.  I've seen some that claim "surgical steel' and while that should be good, again, I'm not sure what the standards are, even if there are any.\n\nGo with the gold, either yellow or white (if they like a silver look).  And make sure they're very clean when they change them (clean hands too).

Something that is gold should have a stamp mark somewhere on the bottom.  As far as solid, there should be another stamp mark saying what the purity is.

If you mean pure gold from 6 ozs of 9 ct gold then roughly 2 ozs

Worth of course depends on how many people are wanting to buy it.  On of the best sources to get it out there and seen is to take a picture of it and sell it on ebay.  There is a huge huge demand for minerals/crystals of that nature on there.  I know because I buy alot of my crystals on there.  See if htat works for you.

"Carat" is the unit of mass to measure fine stones.  It's just like any other term of measurement.  Just happened to be named Carat.\n\n"Karat" is the unit of measurement for the proportion of gold in an alloy; 18-karat gold is 75% gold; 24-karat gold is pure gold

The answer seems to be to mix the gold with silver and wrap it in aluminum foil, thus eliminating the possibility of contamination.\n\nSee: http://www.gold.org/jewellery/technology/assay/

The higher the karat, the better. The higher, the closer to pure gold.
