Diamonds are graded for certification by
laboratories using grading criteria. Four of
these criteria are critical to understand when
making a diamond purchase or investment.
Known as the “Four C’s” these criteria are:
color, cut, clarity and carat. 

Color is the result of the composition of a
diamond and it does not change. When a
jeweler is describing the color of a diamond
they are referring to the presence or absence
of color in white diamonds. Because a
diamond with no color allows maximum light
to pass through, colorless diamonds are
preferred for their sparkle.

Cut refers to a diamonds reflective quality.
Most diamonds are cut with 58 facets. The
brilliance of diamonds is heavily dependent
on the cut. The different angles and the finish
of a diamond determine its ability to reflect
light and cause its brilliance and fire.
Remember that the cut of a diamond can
have an impact on its durability as well as its
beauty. Some cutting faults can make a
diamond prone to breakage. A diamond
that is cut too thin can also cause light to
leak out of the back and the diamond will
lose some of the sparkle and appear not
to shine. So, as you can see the Cut is
probably the most important of the Four C’s.  
 
During the formation process, inner flaws, or
inclusions occur in most diamonds. The
number and size of these inclusions
determine what is referred to as the clarity
of a diamond. Diamonds that are clear
create more brilliance and therefore are rarer
and highly priced. To be considered
“flawless”, a diamond must have no surface
or internal imperfections visible upon being
viewed by a skilled diamond grader using
10 power magnifications.

Carat is the unit of weight by which diamonds
are measured. One carat is equal to 200
milligrams. A carat is divided into 100
segments called points. 150 points would
equal one and a half carats. 

When you go to the store to make that all
important diamond purchase, do not be shy! 
Ask questions, get the answers needed to
make an informed purchase. Shopping for
certified diamonds enables you to make an
informed selection. Knowing the “four C’s”
allows you to comparison shop and purchase
the best diamond at a fair price.  But, before
making a purchase, shop around and decide
what shapes and styles really appeal to you.
Enjoy your diamond for years to come!

In this world of advanced technology it is
almost impossible to simply look at a
diamond and determine whether it is real or
not – especially if you don’t know much
about diamonds. There are some steps that
you can take to avoid buying a fake diamond,
however.

First, only deal with reputable jewelers, and
when you find a reputable jeweler, stick with
them. Avoid buying diamonds or other
jewelry from jewelers that you have never
dealt with before in the past. Ask to see the
certificate for the stone. If no certificate exists,
walk away.

Look at the setting that the stone is in. Fake
diamonds, such as zirconias, are usually set
in low quality metals. Take a close look at the
stone. Fake diamonds are not durable –
natural diamonds, on the other hand, are the
most durable stone on the planet. Look for
scratches or nicks.

After purchasing a diamond, take it to
another jeweler for appraisal. In fact, take it
to two or three other jewelers for an appraisal
to make sure that the appraisals are all fairly
close. If you find that you have purchased a
fake diamond, you may be accused of
making a switch when you return to the store
of your purchase; therefore, it is important to
have a certificate for the diamond. No two
stones are alike.

Caring for a diamond takes more than
occasional cleanings. Diamonds are forever,
but they can be damaged if you are not
careful. By learning how to properly care for
your diamond, you will ensure that your
diamond is indeed forever.

First, you should take your diamond jewelry
to a jeweler once a year. Have him check the
mountings and prongs that hold your
diamond in place. Have him make any
needed repairs. This will prevent your
diamond from falling out of its setting and
becoming lost.

Diamond jewelry that is not being worn, or
diamonds that are loose should be stored in
a fabric lined jewel case, or in a jewelry box
where it can be kept separate from other
jewelry. Each piece should have its own
compartment. This will keep diamonds from
becoming scratched, and it will also keep
your diamond from scratching other jewelry
as well.

Remove your diamond jewelry when doing
physical work. Diamonds can be chipped
and scratched easily. Also avoid allowing
your diamond to come into contact with
bleach or other household cleansers – this
can damage or change the color of the
settings and mountings, and it may even
irreversibly change the color of the
diamond!

There is much to consider when purchasing
a diamond – especially diamond
engagement rings! The tradition of
presenting a woman with a diamond
engagement ring when proposing began in
1477 when Archduke Maximilian presented
a diamond ring to Mary of Burgundy – and
in most cases, the woman you plan to
propose to will expect a ring to accompany
that proposal!

First, determine how much ring you can
afford. Most people use the ‘two months
salary’ rule. This means that the ring should
cost the equivalent of two months of your
current salary. Because you have other bills
to pay, saving up this amount of money may
take quite a bit of time. You should consider
financing. Simply go to the jeweler of your
choice and tell them that you plan to buy an
engagement ring, and that financing will be
necessary. Go ahead and get the credit
check out of the way, find out what your
payments will be, and how much of a down
payment is required.

Now, have your mother, sister, or your
girlfriends best friend take your girlfriend
shopping, and make sure that they gaze at
the engagement rings to get an idea of what
she might like. Make sure that the jewelry
store you buy the ring from will allow you to
return the ring, if that is required, or allow
your girlfriend to exchange it for another if
she isn’t happy with it!

When it comes to diamonds, there are
numerous scams to avoid. Most 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.

A common 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 leads consumers to believe that the main
diamond in the piece is actually bigger than it
is. Ask what the total carat weight of the center
stone is. Also beware of fractions. Jewelry
stores are allowed to round off diamond
weights. This means that if the jeweler tells
you that it is a ¾ carat diamond, it is
probably between ½ and ¾ carat – but
closer to ¾.

Jewelry stores often run ‘fluorescence’
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. Jewelry stores
also like to show their diamonds in bright
lights. Lights make diamonds shine. Ask
to see the diamond in a different, darker
type of lighting as well.

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 any action.

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 past.

There are many more scams that jewelry
stores commonly pull on unsuspecting
consumers. Just use your best judgment,
and purchase your diamonds with the
utmost care and consideration.

You’ve been told that having a certificate or
a diamond grading report is important, and
as a responsible consumer, you get one –
unfortunately, you probably won’t understand
a word of what is on that diamond grading
report, unless you are a jeweler.

On the color grading scale, D, E, and F
mean that the diamond has no color. G, H,
and I means that it has very little color. J, K,
and L means that the diamond has a slight
yellow color. P, Q, R, S, T, U, V, W, and X
means that the diamond is a darker shade
of yellow. Z means that the diamond has a
 fancy color – other than white or yellow. 
On the color grading scale, D is the most
valuable, and X is the least valuable –
however diamonds that get a Z rating are
 the rarest and most expensive diamonds
in the world.

There are many aspects to a grading report.
Figuring it all out can be very confusing. You
should talk to a jeweler you trust, and have
them explain everything on the diamond
grading report to you.

Diamonds are one of the few products that
simply cannot be ‘branded.’ Even though
there are different cuts, different grades, and
different values placed on each and every
diamond in existence, no diamond is any
specific brand – just as gold is not a specific
brand.

Branding is actually based on who owns the
diamond. For instance, if DeBeers owns the
diamond, it is a DeBeers Diamond – but it is
still just a diamond. If the diamond was cut by
a specific well known cutter, then it might be
branded in that way as well – but it usually
isn’t. It is still branded based on who owns it
at the time. So basically, when it comes down
to it – diamond brands mean absolutely
nothing at all.

Do not allow a jeweler to try to talk you into
paying an exorbitant price on a diamond
because it is a specific brand. This is a bit
of trickery used by unscrupulous jewelers
when they know that they are dealing with
people who don’t know much about
diamonds. Remember that diamonds are
not actually branded – unless mother nature
has her own brand!

Before you start shopping for diamonds,
consider dealing with a bonded jeweler.
Bonded jewelers sell bonded diamonds,
and there are very few bonded jewelers in
the world. In fact, out of all of the jeweler’s
in the world, only about 5% of them are
bonded. Buying a bonded diamond will
cost more than buying a non-bonded
diamond, but when you look at what you
get with the bonded option, you will see
that it is well worth the extra expense.

First, bonded diamonds have a buy back
policy for the life of the diamond. No matter
how long you have had the diamond, you can
take it back to the bonded jeweler and sell it
back to him or her, for a 100% refund. If a
jeweler does not offer a 100% buy back
guarantee, for the life of the diamond, then
you should take a closer look at the diamond
to see what is wrong with it.

Bonded diamonds also have a breakage
policy. If the stone breaks or chips, the
bonded jeweler will replace it with a new one
– one time. No jeweler would ever offer such
a policy on any stone that was not 100%
natural, so just the offer of such a policy
should give you piece of mind concerning
the quality of the diamond. Bonded
diamonds are natural and untreated.

Bonded diamonds increase in value, with a
fixed appreciation rate that is designed to
keep up with inflation. This means that a
diamond that is worth a certain amount of
money today will be worth more in the future,
as the price of diamonds continues to rise.
This generally does not apply to buy backs,
however. It typically applies to trade-ins.

Alternately, by purchasing a bonded
diamond, you are protected against the
possibility of a market crash. If a market
crash occurs, the value of diamonds will
drop. However, the bonded jeweler
guarantees to refund you the difference
between what the diamond is now worth
and what you paid for it before the market
crash.

It may be difficult to find a bonded jeweler in
your area, but if you can, this is who you
want to deal with, as opposed to dealing
with an un-bonded jeweler. Specifically tell
the jeweler that you are only interested in
bonded diamonds.  You can find a bonded
jeweler in your area by using various online
resources, or by calling the local jewelry
stores.

Diamonds are measured in Carat Weight.
One carat weighs 200 milligrams. If a
diamond is referred to as four grains, this
also means that it is a one carat diamond.
The word Carat comes from the word carob.
A carob is a bean that grows on a tree in the
Mediterranean. In times past, if a diamond
weighed the same as a carob bean, it was
one carob, or one carat.

However, in the far east, where Carob trees
do not grow, rice was used to measure the
weight of a diamond. If a diamond weighed
as much as four grains of rice, it was four
grains – or one carat as we know it to be
now. The majority of diamond purchases
are for diamonds that are 1/3 of a carat.

Beware when shopping for diamonds that
are already set or mounted. If more than one
diamond is used in the piece, the tag on the
jewelry will give the CTW or Carat Total
Weight – it does not tell you the carat weight
of each stone in the piece. You need to ask
the jeweler for the total carat weight of the
largest diamond in the piece to truly
understand what you are buying.
