Are Diamonds Really Rare?

When you walk into a jewelry store and see
all the diamonds in all of the various settings
that are for sale, it is difficult to realize that
diamonds are indeed rare. Most people
don’t even stop to consider how that
diamond came to be sitting in that jeweler’s
case! There is quite a bit of work that is done
before a diamond is ready to sell to the
general public!

For every one million diamonds that are
mined, only one will be found that is a quality
one caret diamond. In order to find a two
caret diamond, about five million diamonds
must be mined. More than two hundred tons
of ore must be mined to find one small
diamond, and even then, more than 80%
of the diamonds that are mined are only
good for industrial use, such as diamond
drill bits.

So, the next time you visit your local jewelry
store, ask to see the one carat diamonds.
You should look at this diamond with new
appreciation – knowing that it truly is one
in a million!

About Diamond Weights

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.

How Diamonds Are Mined

We seldom think about how the diamonds
we wear came to us. Natural diamonds, as
opposed to synthetic diamonds or fake
diamonds, are mined from the earth. There
are currently two methods of mining
diamonds: Pipe Mining and Alluvial Mining.

When pipe mining is used, the diamonds
are extracted from the earth through volcanic
pipes. These are not man-made pipes. These
are natural pipes in the ground. Shanks are
put into the ground next to the pipes, and
tunnels are driven into the deepest parts of
the pipe. The diamonds are not sorted out at
the mine. Instead, huge rocks that are full of
diamonds are brought out of the mine and
moved to a screening plant for separation.

The Alluvial mining method is done in
riverbeds and on beaches. Walls are built to
hold back the water and the sand on the bank
or beach is moved with a bulldozer until the
level of earth that diamonds can be found in
is reached. Again, the diamonds are not
sorted here. Instead, the sand that contains
the diamonds is bulldozed into trucks, and
taken to screening plants.

How to Buy Diamond Engagement Rings

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!

How Diamond Prices Are Determined

Pricing most products is quite easy.
Determine how much it costs to make the
item, how much it costs to market that item,
and then mark it up by 15 – 30% or more.
Simple, right? Well, pricing diamonds isn’t
quite that simple. There are many factors
that are considered when diamonds are
priced.

Diamond prices are determined first by
adding the cost of the rough diamond, the
cost of cutting the diamond, and all other
costs necessary to turn the rough diamond
into a marketable diamond. Depending on
the importance of the diamond, an
independent company may be called in to
certify the grade of the diamond based on
color, cut, clarity, and weight.

At this point, the diamond becomes more
expensive each time it changes hands, until
it finally reaches a retailer, where the price is
raised a bit more. Before reaching the
retailer, however, the diamond must travel
from the mine, to the cutter and polisher, to
the independent grading company, and
then to the Primary market. Once it has
reached the primary market, it will be
purchased by diamond dealers and
wholesalers, and from there it will be sold
to retailers.

As you can see, the earlier you can purchase
a diamond in the process, the lower the cost
of the diamond will be – but not the value.
The value is based on what the diamond will
sell for in the market place – through a retailer.

If you own a diamond, and you have no idea
how much it is worth, you can have it
appraised, but the appraisal may not be
accurate. You will be better off obtaining a
certificate through GIA – Gemological Institute
of America. With the information on this
certificate, you can use a cutter’s guide to
accurately determine what your diamond is
worth.

There are also many diamond price
calculators available. These can be found
on the Internet, and many diamond dealers
use these as well. You must realize, however,
that before you can accurately price a
diamond, without a Diamond Grade Report,
you need to know quite a bit about diamonds,
such as different cuts, clarity, color, and weight
– and how each of those aspects adds to the
value of a diamond, or decreases the value of
the diamond as the case may be.

Again, you will be better off if you get a
Diamond Grading Report on the diamond,
and use that information to look up the price
in one of the guides that the diamond cutting
industry uses. This will give you the most
accurate value of the diamond in your
possession, or of the diamond you are
considering purchasing.

How Diamonds Are Cut

In their most natural form, diamonds are –
well – quite ugly. They have no luster or shine,
and in fact, look like nothing more than
broken glass. A diamond must be cut, and
then polished before it actually becomes a
thing of beauty.

Diamonds are cut with saws, into round
shapes. From the rounded shape, other
shapes may be cut, such as heart shapes
– but the shape is less important than the
quality of the cutting that is being done. If
the diamond is poorly cut, it will lose light,
and it will not sparkle and shine very well.
Each facet of the diamond must be
carefully cut into the geometrical shapes
that allow the diamond to sparkle and
shine, then the entire diamond is cut into
a specific shape, such as an emerald cut
or a princess cut diamond.

Once the cut is done, the diamond is put into
a dop, which resembles a cup with another
diamond – only a diamond is strong enough
to smooth the edges of another diamond.
Once the diamond has been cut and shaped,
and had the edges smoothed in the dop, it is
polished on a scaif or a diamond polishing
wheel.

Famous Diamonds


Among the most well known diamonds is the
Hope. This 45.52 carat steel blue diamond
is currently on display at the Smithsonian.
The legends of the ill-fortune and curse
bestowed on the possessor of the Hope
Diamond are many. This diamond was
donated to the Smithsonian in 1958. The
Hope was originally a rather flat, blocky
110-carat rough.

The Dresden Green stands out among the
natural colored diamonds. It is the largest
green diamond in the world weighing
40.70 carats. This diamond is historic, large
and has a natural green color with a slight
blue overtone. These facts make it virtually
priceless.

The Conde Pink is a pear shaped and
weighs 9.01-carats. This pink diamond was
once owned by Louis XIII.

The Tiffany Yellow diamond a beautiful
canary-yellow octahedron weighing 287.42
in the rough (metric) carats discovered in
either 1877 or 1878 in South Africa. The
gem after cutting boasts the extraordinary
weight of 128.54 carats. And until recently,
was the largest golden-yellow in the world.

The Koh-I-Noor ( Mountain of Light ) is now
among the British Crown Jewels. This
diamond weighs 105.60 carats. First
mentioned in 1304, it is believed to have
been once set in Shah Jehan‘s famous
peacock throne as one of the peacocks eyes.

The Agra is graded as a naturally colored
Fancy Light Pink and weighs 32.34 carats.
It was sold for about 6.9 million in 1990.
Since this sale, it has been modified to a
cushion shape weighing about 28.15 carats.

The Transvaal Blue is pear cut. This blue
diamond weighs 25 carats. It was found in
the Premier Diamond Mine in Transvaal,
South Africa.

The Great Chrysanthemum was discovered
in the summer of 1963, in a South African
diamond field. This 198.28-carat fancy
brown diamond appeared to be a light
honey color in its rough state. However,
after cutting, it proved to be a rich golden
brown, with overtones of sienna and burnt
orange.

The Taylor-Burton Diamond is a pear-shaped
69.42 carat diamond. Cartier of New York
purchased this diamond at an auction in
1969 and christened it "Cartier." The next
day Richard Burton bought the diamond
for Elizabeth Taylor. He renamed it the
"Taylor-Burton”. In 1978, Elizabeth
Taylor put the diamond up for sale.
Prospective buyers had to pay $2,500
each to view the diamond to cover the costs
of showing it. Finally, in June of 1979, the
diamond was sold for nearly $3 million dollars.

Diamond Scams

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.
