Tiffany Yellow

The Tiffany Yellow diamond a beautiful canary-yellow octahedron weighing 287.42 in the rough 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.

Mountain of Light

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

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.

 Great Chrysanthemum

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.



Taylor-Burton

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.

The One In A Million

When you walk into a jewellery 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 jeweller’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 carat diamond. In order to find a two carat 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 jewellery 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 Grading Reports And 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.

Five Diamond Scams To Look Out For

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.

Carat Total Weight
A common scam that most jewellery stores participate in is the Carat Total Weight scam. The tag on the piece of jewellery, usually a ring, only states the total carat weight of all diamonds in the piece, instead of listing the 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 carat weight of the main stone is.

Fractions

Also beware of fractions. Jewellery stores are allowed to round off diamond weights. This means that if the jeweller tells you that it is a ¾ carat diamond, it is probably between ½ and ¾ carat – but closer to ¾.

'Special' Diamonds & Lighting
Jewellery 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 jeweller will try to make you think you are getting something special. Jewellery 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.

Appraisals
Some truly unscrupulous jewellers 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.

Switch Diamonds
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 jewellery, or leave a diamond ring to be sized. The only way to avoid this is to do business with one trustworthy jeweller. Avoid jewellers that you have not done business with in the past.

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

How To Determine Diamond Prices

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 colour, cut, clarity, and weight.

Before reaching the retailer, 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. The diamond becomes more expensive each time it changes hands, until it finally reaches a retailer, where the price is raised a bit more.

The value of a diamond is based on what the diamond will sell for in the market place through a retailer. 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.

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 diamond price guide to accurately determine what your diamond is worth.

There are also many diamond price calculators available on the Internet, and many diamond dealers use these as well. You will realize 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 to purchase.

Quick Guide to Selecting Diamonds

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.

Colour
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
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.

Clarity

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
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.

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!

Diamond Mines Around the World

Argye mine located in the Kimberley region in the far north east of Western Australia. Owned by Rio Tinto, this mine is the world’s largest single producer of volume of diamonds. However, due to low proportion of quality diamonds it is not the value leader. It does produce 90-95% of the world’s supply of pink diamonds.

Diavik is also owned by Rio Tinto, located in Canada, it is a very large mine. It is located north of Yellowknife and south of the Artic Circle on an island. The island is connected by an ice road. It is also an important part of the regions economy employing more than 700 people and producing more than 8 million carats annually.

Ekati diamond mine is owned by BHP Billiton and located south of the Artic Circle in the Northwest Territories of Canada. The Ekati is Canada’s first operational diamond mine. Diamonds mined here are sold under the Aurias trade name. Authenticity is verified through CanadaMark service. CanadaMark service is also owned by BHP Billiton Diamonds, Inc.

Baken diamond mine is located along the lower Orange River in South Africa. It is owned and operated by Trans Hex. The average size stone for 2004 was 1.29 carats. In 2004, this mine produced a 78.9 carat D color flawless diamond that sold for more than 1.8 million US dollars, as well as a 27.67 pink diamond that was sold for over 1 million US dollars.

Merlin is the second of only two diamond mines in Australia. It was once owned by Rio Tinto and sold to Striker Resources, and subsequently became North Australian Diamonds.

Orapa is the world’s largest diamond mine. It us located 240 Km west of Francistown. The mine is owned by Debswana, which is a partnership between De Beers and the government of Botswana. This mine operates 7 days a week. It maintains pre-primary and primary schools for its employee’s children. There is also a 100 bed hospital and game park. This mine began production in 1971 and is the oldest mine owned by the Debswana Company.

The Premier mine located in Cullinan, South Africa produced the largest diamond, the Cullinan Diamond, ever in 1905. The rough Cullinan Diamond weighed 3,106.75 carats (no. 17 in photo). The famous Hope Diamond, 44 carats, (no. 11) is small compared to the Cullinan Diamond.

This mine also produced the Golden Jubilee diamond which weighed 545.67 carats. This mine is formally owned by the De Beers Company and was renamed The Cullinan Diamond Mine in 2003 in celebration of its centennial. It was sold to Petra Diamonds in November 2007.

Recently, in September 2009, yet another giant 507 carat white diamond was discovered in the Cullinan mine.

Diamond Carat Weight

The Carat

Diamonds are measured in the unit weight carat. One carat weighs 200 milligrams, and is subdivided into 100 points with each point equal to 2 milligram. 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.

The Grain

A diamond is also referred to as four grains, this means that it is a one carat diamond. 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.

Carat Total Weight

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 jewellery will give the CTW or Carat Total Weight – it does not tell you the carat weight of each stone in the piece.

Remember, two 1/2 carat diamonds is not equivalent to a 1 carat diamond, pricewise, due to the rare nature of larger diamonds. You need to ask the jeweller for the carat weight of the largest diamond in the piece to truly understand what you are buying.
