Gold and Quartz fake gold nuggets.
There are bunches of these around as well. These are considered the worst of the fakes and easiest to spot, the reason for that is because they are a pathetic attempt at making a natural nugget by putting chips of quartz and other rocks in the gold. They are BLATANTLY OBVIOUS fake gold nuggets. These nuggets were all bought online in 2002 by some unfortunate people, they were sent to me to verify and test.
Above is a picture of the suspicious gold nugget and then below its shown at 15X magnification.
I know your an intelligent person and therefore I ask you this question? Why are some gold nuggets so smooth and pounded? Of course you know the answer to that is that because they have been in the creek or river! Now ask yourself this? What kind of rocks do you see near a creek or river? They are rounded and smooth, aren't they? Just like the gold!! So HOW IS IT POSSIBLE FOR A VERY SMOOTH GOLD NUGGET TO HAVE SHARP AND COARSE CHUNKS OF ROCK IN IT? Your right!! IT ISN'T!! You just answered the question for yourself!! The picture above shows sharp and jagged quartz and some other blackish colored rocks and the picture below shows an air bubble as well that popped as this fake was cooling.
As you will again see, there are a bunch of gold beads sitting on top of this mud stuff. The other thing you will notice here is that along the edges of where the gold meets the pseudo quartz the gold is mushed out, or rolled over, from polishing. And as I mentioned above, why is the quartz not rounded and smooth? like the rest of the nugget?!!Just a few more and you will be an expert!!
Nice Nugget!! And with a picture that is not quite as crisp as the one above one you wouldn't know any different but with this picture being very crisp you can almost tell...... the bright little spot? In the upper right area of mud, What is that? At 30X magnification in the picture below on the extreme right we see 5 gold beads and 1 of them is slightly mushed from polishing. The top arrow shows a nice round one sitting in the mud!! And the bottom one shows a very flattened BB. Not so nice after all HUH??
And now for the last 2.
This one is tougher to tell by just looking at this picture, but under 30 power......... The give away here is the little pools of brighter, and more yellow deep areas of the nugget. These areas have zero scratches and are not worn at all. There is no way for the manufacturer to polish these low lying areas, and therefore still retain the melted appearance. In nature these low lying areas DO get worn from the millions of particles of sand that travel over them in the creeks and rivers.
This nugget below is a hastily and not too carefully made fake gold nugget.
Ever see an aluminum can after its been in a camp fire? Or a piece of tin foil from a cigarette pack? Looks pretty similar to this top portion of nugget!! I guess he forgot to polish this one? In the picture above you can almost see it easily with just your naked eye, but with 15X magnification its REALLY easy to see as shown below.
Ok and finally how to test nuggets easily.
The top picture below is a nugget that I suspected to be fake. It was sent to me for testing. Under the microscope I saw indicators so I did the test and the 2nd picture below shows the result!! This is the same nugget after it has been heated to red hot, with a mini torch, then allowed to cool. If you have a nugget you have decided is suspicious you can use this test, to reaffirm your suspicions. How the test works is basically this, the man-made nuggets are made from scrap jewelers gold, or gold dust with alloys added usually. One of the common alloy's is copper (14k gold has gold, silver, and copper as a rule), when copper is allowed
to heat in the air and then left to cool it forms 2 byproducts. The first is a black oxide (that you see in the sample above) called cuprous oxide, the 2nd is a pink and harder oxide called cumospric oxide, and since most natural nuggets contain only a small amount of copper they generally don't turn this black from heating and cooling!! You may get some smaller black spots on a natural nugget, and even get other discolorations because of many types of natural alloys. You can use a wind-proof cigarette lighter, butane mini-torch (available on Ebay for about 10 bux), or a welding torch even, (be careful!), heat the nugget to cherry red, and let it cool!! If it shows a high degree of black on the nugget, like it shows below it is another indicator pointing towards a man-made nugget. At that point you should get an expert to examine your nugget for you, to fully decide. I will do examinations for you at no charge as long as shipping is paid both ways. An experienced jeweler may be able to help as well!! Good Luck on NOT finding too many black ones!!
