Common Diamond Scams
What are 6 of the most common diamond
When it comes to diamonds, there are numerous scams to avoid. Most diamond scams are minor, but there are some
major ones that come up from time to time concerning the buying and selling of diamonds. Scams occur simply because
most people who buy diamonds – for whatever reasons – don’t know that much about diamonds. Therefore, they are
easily fooled by these common diamond scams.
Carat total weight
A common diamonds scam that most jewelry stores participate in is the Carat Total Weight scam. The tag on the
piece of jewelry, usually a ring, only states the total carat weight of all diamonds in the piece, instead of
listing the total weights separately for each diamond. This can lead the buyer to believe that the main diamond in
the jewelry piece is actually bigger than it is. Always ask what is the total carat weight of the center stone
Rounding up carat weight
Another thing to watch out for is diamond weight fractions. Jewelry stores are
allowed to round off diamond weights. This means that if the jeweler tells you that a stone is a 5-carat diamond,
it is probably between 4 and 5 carats, but closer to 5-carat weight. If you are not paying attention, you will be
paying for a full 5-carat weight. Depending on the value of the diamond, this small fraction could mean paying
extra, even though you're not quite getting the full value.

in a darker type of lighting, for more realistic appraisal.
Jewelry stores often run ‘fluorescence’ diamond scams to varying degrees. Referring to a diamond as a blue-white
diamond is such a scam. A blue-white diamond sounds very unique and special, but in fact, this type of diamond is
of lesser quality – even though the jeweler will try to make you think you are getting something special.
Bright lights scam
Jewelry stores also like to show their diamonds in bright lights. Lights make diamonds shine, which is one of
the reasons why we buy them, especially brilliant diamonds. But they should shine in the normal, natural light, not
being enhanced by bright lights. Ask to see the diamond in a different, darker type of lighting as well, which will
give you a better idea of the diamond's true brilliance.
Some truly unscrupulous jewelers target those who want appraisals on diamonds that were given to them as gifts
or that were purchased elsewhere. They will try to tell you that the diamond is worthless, or worth less than it
actually is worth – and offer to take it off your hands or trade it for a much better diamond, along with the cash
to make up the difference. This is called low balling. Get a second, third, and even a forth opinion before taking
Another common dirty trick is to switch the diamond you have chosen and paid for with one of lesser quality and
value when you leave it to be set in a piece of jewelry, or leave a diamond ring to be sized. The only way to avoid
this is to do business with one trustworthy jeweler. Avoid jewelers that you have not done business with in the
There are many more diamond scams that jewelry stores commonly pull on unsuspecting consumers. Just use your
best judgment, and purchase your diamonds with the utmost care and consideration, to avoid being a victim of
