Hello and welcome. Have you found what you think is natural gold (nuggets) or coins, jewellery etc.?

You can eitehr chedk on it be checking its volume & weight or by applying an acid test. The later one can also be performed by an jeweller or pawn shop etc.

Best wishes,

Christian

Hi Kunook
                The professionals use a small emery stone they call a touch-stone they rub a gold item on the stone and compare the gold mark against a chart then determine what carat the gold is  this method is used for jewelery . another method is to use Hydrofloric acid ,  Gold is not affected by acid but anything else will dissolve .   usually a drop of acid is dropped on the gold item to see what effect the acid does .  
               There are several other methods,  To have the gold item assayed (ie) gold nugget they use heat and use a spectrograph to annalise  the specimen or weigh the specimen to work out how much gold and other impurities are in a knowen volume .
               This specimen has been etched with acid  you can see the gold is unafected but the stone has been eaten away

Hi,

I know this is an older post but as I worked at pawn shops in the past, thought I'd share.  Most of this is in
reference to testing jewelry... but the same generally holds true for raw gold.

How we checked it was to (assuming scrap item) file a small area to get past any plate.  Then a small drop
of nitric acid on the spot would produce a reddish-brown color.  One tended to get used to the variances of
color to know what karat it was.  On nice items we would rub the item on a scratch stone.  Then you take a
gold needle (whatever karat the customers item was marked) and scratch this on the stone as well.  A drop
of nitric acid on both marks and one should see the same color.  Truth is, after a few years of working with
gold you learn a certain "feel" to real gold.  They (crooks) are always trying something new, but you tend to
have an instinct for the real deal.  Note, a lot of chains are also coated with rhodium (for shine) so a drop
of acid on an unfiled area may give incorrect results.

These days I have the acid on hand as I enjoy the occassional foray into gold prospecting/panning and also
like to check old rings I dig up.  Acid/test kits can be had off the Internet.

They now have electronic gold testers, but I'm old school and don't really trust them (I've seen one call some
scrap material from a computer mfg company 18KT and it was gold colored trash... probably read the plating).

Hope someone finds this useful! Smiley

I found the easiest and cheapest way to determine if you have a gold or not is to use a jeweler's reagent kit which consists of various asset combinations and gold pins of various karats. You usually get these from any jewelry supply house in various locations located on Internet and nearly usually only runs about $20 or so in price.
