How can a jeweler tell what type of gold you have, and if its real or fake?

There are many different types of gold jewelry, from 4k-24k. Jewelers must be able to differentiate amongst these different types to determine the value and cost of the jewelry. The simple solution to this problem are the acid and slab testing system.

The way this works is the gold jewelry is rubbed against a black slab rock and some of the gold rubs onto the slab. Next we pour an acid onto the marking and watch the magic happen. If the color stays this means we have real gold. If the color vanishes and the acid removes the marking we have fake gold!

Now we have different acids for each of the different karats of gold, and this is how we test the gold !

Also, we can use magnets to test gold as well.... because gold is not magnetic !
