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.

Bonded Diamonds

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.

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.

Diamond Brands and What They Mean

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!

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 donebefore 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!

How Diamonds Are Mined

The word diamond comes from a Greek word, "adamus", which means invincible. This is because diamonds are the hardest minerals in the world. They are 1000 times harder than rubies or sapphires. Not even the most powerful acids can harm a diamond's surface.

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 ofthe 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.
