The best way to ensure that the jewelry you buy is real is
to only purchase it from reputable companies. Do some price comparisons before
purchasing. Just like with any other product, if one price seems excessively
low, it’s for a reason. If you do end up with jewelry that you are skeptical
of, the best way to determine its authenticity is to get it appraised
professionally. Yes, it will cost you even more money, but it’s the most
accurate way to find a fake. If this option is out of the question (or you’re
just curious about how testing of jewelry is done), there are several ways to
examine the jewelry for authenticity on your own. Find out how below.
Gold - Use X-Rays |
In the U.S.,
gold under 10 karats (10/24 real gold) is not considered gold at all. A common
problem involves gold being sold as a higher quality than it actually is. The
best way to tell the actual karat of gold is to use x-rays or electronic gold
tests; yet another reason to shop at reputable dealers. But fakes that are gold
plated or not gold at all can be easily identified.
Gold - Find The Official Stamp |
First, look for the official stamp that gives purity. It
will appear as .1-.999 or 10-24k. But keep in mind that the stamp can be
counterfeited and that real stamps may have worn off due to time or repair.
Also, if the jewelry looks poorly made or discolored you should avoid it like
the plague. Look for fading to a darker color; this is a sign that it is gold
plated.
Gold - Test With a Magnet |
Gold is not magnetic and several metals that are passed as
gold are.
Gold - Streak On Ceramics |
An unglazed ceramic surface, such as a tile, can be used for
a test. This will scratch the piece, so perform the test on an area that is not
visible. Simply drag the piece along the tile and examine the mark it leaves.
If the streak is gold, it is real. Fool’s gold (pyrite) leaves a dark streak.
Gold - Home Test Kit |
The cheapest of these is a nitric acid test kit which starts
around $15. Scratch the surface of the gold (again, in an area that is not
visible) and drop the acid on the scratched area. Gold will not react to the
acid. Other metals will react by bubbling. Also, more expensive test kits have
different solutions that can tell the difference between karats.
Platinum, White Gold, Silver - Intro |
All three of these metals are similar in color. Silver is
not often used as small jewelry because it tarnishes easily. Silver flatware,
dishes, and decorations are usually silver plated because silver is such a soft
metal.
White Gold vs Platinum |
The best way to tell the difference between white gold
(which is gold mixed with other metals to bring out a silver color) and
platinum is by weight. Platinum is much more dense than gold and therefore, a
platinum object of the same size as a gold object will be much heavier.
Gold vs Platinum - Scratching |
Also, when gold is scratched, metal will be filed off. When
platinum is scratched, the metal will only be displaced. For lack of a better
example, it is similar to the T-1000 in Terminator 2.
Diamonds - Intro |
Fake diamonds are widespread and a bit more difficult to
detect than fake gold. Once again, buying from a reputable retailer and getting
professional appraisals is the best route to go. There are a few tricks a
layman can perform, short of looking at the stone under magnification (a
jeweler’s loupe), since it takes practice to know what to look for anyway.
Diamonds - Fog Test |
Breathe on the diamond as if you were fogging a window. If
the condensation stays for a few seconds, it is a fake. A real diamond will
clear up immediately.
Diamond - Test Its Weight |
Fakes, such as cubic zirconia, weigh a bit more than real
diamonds. If you have a real diamond to compare, weigh them.
Diamonds - Look At the Setting |
Look for the official stamp on the gem’s setting. If the
stone is set in fake gold or platinum, it is most likely not a real diamond.
Gemstones |
All gemstones are copied. Less rare minerals of the same
color and colored glass are touted as the real thing. Precious gemstones such
as rubies and emeralds are much heavier and harder than imitations. It is easy
to spot the fakes because they can be scratched easier and weigh less. This
doesn’t differentiate between lab-grown synthetics and naturally occurring gems
though.
