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!

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.

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.

Diamond Certificates
A diamond certificate is also known as a Diamond Grading Report. This report comes from the Gemological Institute of America (GIA), and you should require this report when you are purchasing a diamond.
With a diamond certificate, you can verify the color, cut, carat, weight, and clarity of the diamond. You don’t have to worry about a diamond dealer telling you anything less than the truth, because the certificate comes from the GIA – not the dealer. You may be required to pay for the certificate, but the cost is usually low, and in many cases, it will help you negotiate a better price on the diamond – or keep you from purchasing a lower quality diamond altogether.
If you buy a high quality diamond, and then later decide to sell the diamond, you will need to have the certificate, or you will have a hard time selling it to someone else. Furthermore, you can use the Diamond Grading Report to look up the wholesale value of the diamond in question. Use the guide that is used by the diamond cutting industry.
With the Certificate, or Diamond Grading Report, there won’t be any doubts when you are trying to purchase a diamond. You can easily find out what the diamond is worth. This will prevent you from overpaying, and it
can prevent a seller from under-charging as well.
A copy of the Diamond Grading Report should be given to your insurance company as well, when you insure the diamond. This provides absolute, unquestionable proof of the value of the diamond should it be stolen
in the future. Insurance companies cannot argue with the report.
Avoid diamond dealers who seem reluctant to provide a certificate! Also avoid sellers who tell you that a certificate diamond will cost you more – the only additional cost should be the cost of the certificate, which
is low. If the dealer doesn’t want to provide a certificate, then you don’t want to do business with that dealer.
Don’t accept certificates from Gemological Laboratories other than GIA. There are many fly-by-night Gemological labs these days, but in the end, GIA has been established as the most respectable and trustworthy – not to mention oldest – of the lot. So avoid dealers who don’t want to use GIA for certification
purposes as well.
Don’t buy an expensive diamond without paying the extra cost of the certificate. If a dealer tries to convince you to make the purchase without the certificate, or if they want to use a company other than GIA, you can be sure that the dealer has probably greatly inflated the price of the diamond – they have something that they are hiding from you.

Choosing The Cut of A Diamond
There are many different cuts of diamonds to choose from. The cut essentially refers to the shape that the diamond is cut into – unless you are in the diamond or jewelry business, but this shape has a great impact on the much the diamond sparkles.
The most popular cuts are heart, marquise, oval, pear, princess, round, trillion, and emerald cuts. The shape has an impact on how much the diamond sparkles, but the actual cutting itself – when the diamond cutter actually cuts the diamond into a particular shape – also matters a great deal. If the diamond is poorly cut, it will lose its sparkle.
However, in the diamond industry, the cut of a diamond doesn't refer to its shape at all. Instead, this is a reference to the stone’s depth, width, brilliance, durability, clarity, and other aspects of the diamond. Common cutting problems include a missing or off center culet, misalignment, a diamond that is too thick or too thin, cracks, or broken culets.
When shopping for a diamond, you should of course choose the shape that you like the best, but then look at several different diamonds of that shape to find the one with the best cut – the one that sparkles the most, in all types of lighting.

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 carobean, 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.

All About the Clarity of Diamonds
Many people mistakenly think that diamond clarity refers to how clear it is. This isn’t so. Clarity actually refers to the internal and external imperfections of the diamond. The best diamonds, of course get a grade of FL or IF – Flawless or Internally Flawless – meaning that it is perfect. A grade of I-1, I-2 or I-3 means that the diamond is imperfect, with a grade of I-3 being the worst.
Other grades are VVS1 and VVS2, which means that the diamond is very, very slightly imperfect; VS1 and VS2, meaning the diamond is very slightly imperfect; SI-1 and SI-2, which means that the diamond is
slightly imperfect.
