The most primitive way is to "bite".
The more vivid the marks,

you bite it, it will leave marks.
Check the hallmark.
Nearly all real gold is stamped
hallmark to tell you the
fineness or purity.
"14K" means that 14/24,
or 58.5% of
the metal is gold, and can be
either 14K or 585. However, the absence
a hallmark does not always mean the piece is
some really good fake pieces of jewelry will even have a
convincing fake hallmark or stamp, so even this method can be flawed.
Conduct acid test.
Acid testing is based on the fact
that 24K gold resists
all but the
strongest acids. The purer the gold,
stronger the acid required to
dissolve it. Rub gold on
stone to leave a sample and
place a drop of
acid from a 14K
testing bottle. If the acid has
solved the sample, it means
the gold is 14K or
This method requires use of acids, so
careful procedures are a must.
Test gold’s electrical conductivity.
Electronic gold testers utilize the physical
fine gold, various alloys and foreign
material will all
differ in their electrical
conductivity. After applying an
charge to a sample, the tester

gold alloy conductivity signature. Electronic
goldtesters are fairly accurate when used properly.
Check spectral signature.
This method utilizes the fact that fine gold,
alloys and foreign material will all
differ in their
response to near infrared light.
