Do You Think This Chain Could Be Real Gold?
Written by Admin on January 7, 2010i got a anxiety and its stamped 14k, but for some conceive i was a small sceptical. i took a small compile conceive of member of the instruction but i formation avow if there is additional metal underneath it and i dont impoverishment to find a super chunk. i also dilapidated a mixed conjugation and i havent effect additional metal ease and i dilapidated it pretty deep. but the small “O” anulus that holds the aggregation to the anxiety is attracted to a magnet, but not the anxiety or the aggregation though. i am accomplishment to avow it to a creator tomorrow, but its dynamical me nuts! could it be a noise beatific fake? it is stamped “14k ITALY” thanks!
P.S. i impact no aim what assemblage this handle is supposed to be in, there isnt member for jewelry!

If you cannot tell if it is real gold from scratching it, and you don’t want to melt it down and have it analyzed by metal analyst company, the best thing to do is probably to take it to a pawn show where they will do an acid test.
It sounds daunting, but its a simple test that doesn’t harm your jewelry, it doesn’t cost a lot (sometimes they will do it for free), and they can even tell you what carat you’ve got. Pretty much the easiest thing to do, besides going to a jeweler and having them test it, although they are usually more reliable (and more expensive).
good luck finding out.

To check for gold you need to measure the density. Gold is a rather dense element 19.3 grams per cubic centimeter. Lead is 11, mercury is 13, iron is 8 or something like that.
In order to check the density, you need to measure the size of the metal in the chain. To do this you would need a small tube partially filled with water. Mark the level of the water, then put the chain in, then measure the level of the water again. The difference in levels = the size of the metal in the chain! Then you need to weigh the chain accurately. Once you have both the size and weight, you can calculate the density which is weight/size. In metric, gold is 19.3 grams per cubic centimeter. You will need metric conversions if you didn’t use metric measurements. The density of silver is 10.5 so if you can measure the density of your chain, you could use math to figure out what % is gold, assuming the chain is an alloy of silver and gold. Gold jewelry is also often an alloy of gold and nickel which has a density of 8.9
I know this sounds difficult but scratching will tell you nothing.
A carat in terms of gold is 1/24 pure. So 18 carat gold is 18/24 = 75% pure. 14k is about 58% pure. To put it simply, if you measure the density of your chain and assume it is a gold-nickel alloy and is 58% of the way from 19.3 to 8.9 then it is 14k gold.
That calculation, if the density you measure is x:
the percent gold would be 100 * (x – 8.9) / (19.3 – 8.9)
The carat is percent / 100 / 24
For example, if you measure a density of 12.9 then
100 * (12.9 – 8.9) / (19.3 – 8.9) = 38 (38%)
The carat would be 38/100*24 = 9.2k
However, as you can see, it depends a lot on what the gold is alloyed with, since the density of nickel and silver is quite different, and the alloy may have other elements in it instead or in addition.
You really need a jeweler.
