which, 24K gold is the pure one; 18K gold contains 75% (18X100:24) pure gold;
14K one contains about 58,3% (14x100:24) pure gold,... Below are the most
simple and exact ways to distinguish fake and real gold:
By observing:
Sign to recognize real gold lies in the outside features which
are:
The change in color: Pay attention to the carved
areas to find if the color in these areas is different or not. If the color is
the same as the other areas, it is real gold. If the color is different (dark,
black or blue), it is fake gold.
The surface of gold: Use magnifying glass to observe.
If the surface has wrinkle or small dots, gold is fake.
By biting

not by biting.
You should bite it not too strongly and not too lightly. After that, observe
the bitten area. Real gold is concave. Fake one remains the same without any
concave area because it is tougher than real gold.

based on weight

way. Gold's weight is counted by gram. You can ask the jeweler to know your
gold's weight. Put gold into a tube of water which has volume measurement to
figure out gold's volume.

Real gold's proportion is approximately 19g/ml.
For example: The gold's weight is
40g and its volume is 2ml. Its proportion is 20g/ml (40:2). We can confirm that
this is real gold.
Below are proportions of some
kinds of gold:
- 22K : 17,7-17,8 g/ml
- 18K (white gold) : 14,7-16,9 g/ml
- 18K : 15,2-15,9 g/ml
- 14K : 12,9-14,6 g/ml
By using pottery

distinguish real from fake gold: Rub gold on the ceramic surface. Fake gold
turns black. Real gold stay the same.

or remain the original color. Fake gold becomes green or blue.
