How do you tell gold carats?

Look-like gold jewels are sometimes too much brighter or as dark as copper as it's quite hard to reach the exact color of an 18 carat gold which is unique...

plated gold jewels look exactly like a gold jewel, but the metal they use will lie for or it's rough or too heavy or even too light...

The best thing if you're about to buy a gold jewelery is to buy it at a well known Gold jewel shop...:-))

you can tell if you look on the flask of the necklace you have. or it is somewhere on the ring.
