Executive Summary about Man Made Diamonds by James Chartwell

The incentive to create man made diamonds resulted from the desire of scientists and researchers to improve technology at a much lower cost than expensive mined diamonds.  Valued for their brilliance and luster, diamonds are also extremely hard and durable.  In his short story, “The Diamond Maker”, writer H. G. Wells, also referred to the concept of synthetic diamonds.

Political commentary and science-fiction aside, man made diamonds are produced in two ways: synthetic and simulant.  Synthetics are exact in structure and chemistry as natural diamonds.  The first stone in the history of man made diamonds was Moissanite, a simulant.  The iron contracted on rapid cooling, generating the high pressure required to transform graphite into diamond.

Others duplicated Moissan’s process, but produced only very small diamonds.  Ruff in 1917 and Dr. Willard Hersey in 1926, both “grew” these tiny diamonds.  McPherson College still displays Hersey’s synthetic diamond in Kansas at its museum.

Sweden’s major electrical manufacturing company in Stockholm, ASEA, produced a true synthetic diamond (exact structure and chemistry as a diamond) in 1953.  This formation of a synthetic diamond, however, was never published. So, when General Electric’s Tracy Hall produced in 1954, via a “belt” apparatus, successfully synthesized a diamond, it was that discovery that was published in “Nature” Colleagues easily replicated Hall’s work, and the industrial man made diamond industry was born, dominated for years by DeBeers Industrial Diamonds and GE Superabrasives.  Producing 3 billion carats or 600 metric tons in 2006, the industrial diamond industry annually brings in $1 billion.

As methods of growing synthetic diamonds improves, more and more companies enter the market, especially for diamonds of gemstone quality.  The history of man made diamonds is fraught with accidents.  Apollo Diamonds and the Russians were seeking a way to create synthetic diamonds to aid science.

Man Made Diamond Types

Those “diamonds” were actually silicon carbide (SiC) and are now classified as Moissanite, diamond simulants.  Others attempted to synthesize diamonds, and only recently succeeded in growing a colorless, pure gemstone quality crystal.

The definition of a man made diamond is straightforward.  As mentioned above, diamond simulants like Moissanite are actually made from other material and look like diamonds.

The classification of man made diamonds types is only done to those crystals that are everything diamond-like.  Four categories of man made or synthetic diamonds exist: HPHT grit; HPHT large single crystal diamond; CVD polycrystalline diamond and CVD single crystal diamond.

Only two processes produce these four man made diamond types.  Developed by General Electric in 1955, HPHT (high pressure, high temperature) replicates the conditions that nature uses to create a natural diamond.  HPHT also produces another type of man made diamond, the large single crystal.

CVD polycrystalline diamond is number three on the man made diamond types chart.  CVD polycrystalline diamond is grown flat, instead of in the cubic and single crystal form of natural diamonds, in a wafer of up to 5 millimeters thick.

CVD single crystal diamond is the fourth man made diamond type.  In 2005, a former Bell Labs scientist discovered a way to grow CVD single crystal diamonds pure and colorless, just like a natural diamond.  With applications in science, this new development also skyrocketed this fourth man made diamond type into gemstone quality.

Executive Summary about Diamond Mines by Lawrence Reaves

The discovery of diamonds in 1867 in the Cape Colony of South Africa had a profound effect on the world’s supply of diamonds. Scientists learned that diamonds came from volcanoes. South Africa still maintains its position as the major diamond producer but there are other famous mines located in other areas.

In North America the oldest and most famous diamond mine is the Crater of Diamonds. De Beers Consolidated Mines are located in several African countries. The De Beers companies make up about 40% of the world’s diamond production.

The Kimberley Diamond Mines are known worldwide and are located in the town of Kimberley, South Africa. In 1866 Erasmus Jacobs discovered a small stone by the Orange River. It turned out that is stone was a 21.25 carat diamond.

The Williamson Diamond Mine, which is also known as the Mwadui Mine is located in Tanzania. It was the first significant diamond mine outside of South Africa. It is an operating pit mine and mainly produces diamond carats.

The Ekati Diamond Mine is Canada’s first diamond mine. It is only accessible by air except for 10 weeks each year when it can be reached by icy roads.

The Kollur Diamond Mine is located in Guntur District Golkonda, India. The Indian mines were eventually depleted and the diamond center shifted to Brazil where new diamond pipes were discovered.

Famous Diamond Mines

Executive Summary about Diamond Mines by Julie Shields

At the time of this writing there are no commercial diamond mines operating in the U.S. Today, there is one non-commercial (that is, unowned by any private company) diamond mining site in operation in the U.S.: Crater of Diamonds State Park in Arkansas. There have been many famous diamond discoveries at this location throughout the decades, including the 40.23 carat Uncle Same diamond discovered at the Park in 1924.

The following are the world’s currently active commercial diamond mine locations: Angola (three mines), Botswana (four), South Africa (eight), Congo (one), Zimbabwe (one), Tanzania (one), Lesotho (one), Russia (five), India (four), Canada (six), Australia (three).

Artisinal mining is also called small-scale mining. This is what is typically used in poor areas and the people who do the mining are called “diamond diggers” who use their hands and very basic tools like shovels and sieves to find diamonds.

Hard rock mining involves creating underground diamond mines featuring “stopes”, or underground rooms that are supported by natural underground pillars.

Marine mining is a relatively new form of diamond mining which hasn’t even been around for 20 years yet. Offshore placer deposits are mined for diamonds; huge drills up to seven meters in diameter are used to drill down into the seabed and suck up the underwater material that contains the diamonds.

Open pit mining is used when the surface material, or “overburden”, that covers the diamond deposits is thin and prospectors find diamonds or what are called kimberlite pipes near or on the surface of an area.

If diamonds are found within alluvial, colluvial, or eluvial secondary deposits, Placer Mining is used for extracting them.

The rough diamonds from diamond mines are treated in a process called cutting diamond, to convert them into gemstones.

Cutting diamond is an art of changing a diamond from a rough into beautiful faceted gem. This job requires special skill and knowledge. And also specialized tools, equipment, and techniques.

The term ‘diamond cut’ means the shape of the diamond. Examples are round cut, oval cut, princess cut, emerald cut, etc. The diamond cut relates to specific quality of the shape. The more quality of a diamond, more expensive is the diamond, and this greatly based on the cut quality.

Diamond stones are the hardest materials ever found. The stones are very hard to cut, so cutting diamond needs special diamond cutting blades.

The process of cutting diamond includes several steps: planning, cleaving, bruting, polishing, and final inspection.

In the planning process, the rough diamond stone is analyzed to decide how the diamond will be cut. This process include the considerations of maximizing value, weight retention, color retention, and turnaround minimization. All of these process is the most time-consuming part of the cutting.

Cleaving or sawing is the separation process of rough diamond into pieces, each piece will be finished as separate diamond gemstone. This process is using diamond saw or laser for cutting the rough diamond stone.

When two diamonds are set to grind against each other in spinning axles, this will make each diamond shaped round. This process called bruting or girdling.

Polishing process is when the diamond is cut and give facets on the gem. This is also the time consuming process which removes material by gradual erosion.

The last step of cutting diamond is the final inspection. This include cleaning the diamond in acid, and examining the quality of the diamond.

Executive Summary about Rough Diamonds by David Cowley

Rough diamonds are still in their natural form and have not been cut or polished. Natural diamonds are found in Octhahedra, Cubic, Macle, and Dodecahedron crystal shapes.

Diamonds was a major trade item in India during the early 1500′s. Brazil then became the next country to develop a diamond trade industry. In the late 1800′s Africa became the most prolific diamond producing country in the world after it was discovered that diamonds are found in volcanic pipes. Only about 30 of the worlds 6,000 volcanic pipes have become major diamond mines.

In the early 1990′s Canada’s Northwest Territories has become the latest entry into the great diamond rush. In 1982 diamonds were found in central Alaska in the Crooked Creek. The largest of all rough diamonds ever found was the the famous Cullinan Diamond. The second largest was the Excelsior diamond which weighed 995.20 carats.

An Octahedra is a polyhedron with eight faces. This is the most common form of a rough diamond.

A simple box shape is in the form of a cube shape.

A Macle is one half of the Octhahedra or pyramid shaped that has been distorted.

A Dodecahedron is has a rounded shape with many different types of flat faces on it. A perfect one will have 20 triangular faces, 30 square faces, and 12 pentagonal faces.

4 Critical Tips on How to Buy Rough Diamonds

Executive Summary about Rough Diamonds by Jared Adams

Because the price and quality of a diamond can depend heavily on how it is cut and shaped, it’s possible to save money by purchasing rough or uncut diamonds for wholesale prices.

Most buyers who opt to purchase rough diamonds then have the diamond cut down into either one or multiple stones by a professional gem cutter or jeweler . Before you make a rough diamond purchase, you need to be aware of the product and the market. So, keep reading for some critical tips that will help you with your next rough diamond purchase.

1. Always use an accredited and respected seller. Even though they’re not yet cut and shaped, rough diamonds are still an expensive commodity.

2. Look for an ethical or conflict-free product. Because rough diamonds are easier to sell and unload on the open market, it’s important that you don’t inadvertently sell an illegally procured or unethical diamond.

3. Always seek an expert’s advice. If you can afford it, bring an expert appraiser along with you when you go to make your rough diamond purchase.

4. Have your rough diamond appraised before and after you bring it to a jeweler.

Executive Summary about Antique Diamond Ring by Joseph Giordano

antique diamond rings

While most people go after a brand-new diamond when shopping for rings, sometimes getting an antique ring can be a better option. Antique rings have an age and unique quality to them. The sentimental value behind an antique diamond ring is easy to distinguish. Research is paramount on picking the right antique diamond ring for your loved one.

No matter where you find the ring of choice, make sure you always try to ensure the authenticity of your antique diamond ring. Get the ring(s) professionally appraised if it does not already have a certificate of authenticity. Having the ring appraised also ensures you of the value of any gems embedded in the ring.

Check and compare the certificate and the antique diamond ring very carefully and make sure they match. Don’t ever try and buy an antique diamond ring from anywhere other than a large and reputable store or outlet.

The biggest drawback to buying an antique diamond ring is that determining the market value can be difficult. Overall, however, antique diamond rings are very romantic pieces of jewelry – especially as engagement and wedding rings.

Say “I Do” with an Antique Diamond Ring

Executive Summary about Antique Diamond Ring by Carl Price

The antique diamond ring is a popular form of jewelry that has usually denoted elegance, prominence, and romantic symbolism.

The Cullinan Diamond, the largest gem-quality diamond in known existence, is part of the crown jewels of Great Britain, having 3, 106.75 carats.

The diamond is very expensive, so any jewelry comprised of diamonds, like the antique diamond ring, has a high gem-stone value. As the diamond ages, the more valuable it is, although its gemstone-value doesn’t necessarily change; the antique diamond ring typically has a higher monetary appreciation than a newer or modern diamond ring.

Antique diamond rings have held other significances as well. Antique diamond rings are keepsakes sold and sought by many at conventions and antique road shows.

What is a GIA Certified Diamond and Why is it Important?

Executive Summary about GIA Diamond by Jan H Roos

Buying a diamond from a wholesale company rather than buying a complete ring from a retailer is a great way of saving money and getting a superior quality stone.

You can prevent yourself from the possibility of being duped by finding a vendor who is GIA certified.

GIA or the Gemological Institute of America is one of the world’s leading authorities on diamonds and gemstones.  The institute carries out this role by identifying and grading any gems that enter the market.   Thus they ensure that the consumer is confident of not being misled whenever precious stones are changing hands.

Reputable wholesale companies allow the GIA to analyze all of their diamonds in order to grade them and confirm that they are genuine.

On top of that, the need for knowing if the gemstones come from ethical sources and methods and the environmental impact minimal is increasingly important.

Executive Summary about Mens Diamond Ring by J Francis Nelson

mens gold diamond ring

Traditionally, it is the woman who, upon being asked for her hand in marriage, is presented with a diamond engagement ring. A mens diamond ring, in those days of yore, was unheard of.

But in this day and age of gender equality and the acceptance of a fashionable man, there is no reason that a gentleman who is due to be wed should not display his love for his fiancée on his finger.

“It’s too flashy for a man.” Many people will argue that a manly man would never wear a diamond, as it is simply too flashy. Maybe it would be, for a less confidant man.

“It demeans the woman’s ring.” Another argument is that the rock on her finger should be the only diamond, and that a man who insists on wearing a stone of his own is competing for attention with his bride-to-be. Engagement rings are her territory, not his.

A modern man would never try to take the spotlight away from his fiancée or her stunning ring, and she knows it.

There are plenty more arguments against a mens diamond ring for an engagement – but the only thing that matters is that it means something to the engaged couple.

Mens Diamond Rings More Than Simply “Bling”

Most people would assume that mens diamond rings would be gaudy, bulky items, worn as outrageous displays of wealth and cockiness. But there is a whole class of diamond rings for the man who wants to show off in a more demure and cultured way.

There are usually three styles of rings that a man might wear that would feature a diamond in some way:

The Engagement Ring. Traditionally in modern Western culture, an engagement ring has been worn by women only. Many men are unaccustomed to wearing jewellery of any sort, so an engagement ring can be a “practice” ring that gets them used to having something on their finger.

The Wedding Band. Again, tradition might attempt to dictate that a man’s wedding band should be simple and plain, with no adornments or identifying features. It should be nothing but a band. But it should be considered that this band will be on his finger, every day, and hopefully for the rest of his life.

The Fashion Ring. A man who wears a ring for fashion is not limited by the narrow views of fashionless and humourless people – he is his own man, who apologizes to no one for his style.

Executive Summary about Pink Diamond Rings by Susan Feingold

ring pink diamond

Becoming all the rage, pink diamond engagement rings add a new twist to the traditional wedding ring with diamond. Traditional diamonds are colorless, it is their cut and shape that creates color effects based on how they capture the light.

Under the perfect conditions during the formation period for a diamond, while it is still in the ground, a gemstone can take on colors. A pink diamond offers a subtle color flair that helps accentuate the engagement ring that you are considering and creates a very desirable effect.

When hunting for the perfect gemstone for your engagement ring set, color is not the only consideration for finding value. Following color you should still keep in mind the diamonds, clarity, carat, and cut. A larger gemstone does not always equal a more valuable diamond, as clarity, cut and color must be taken into consideration as well. Small pink diamonds that are heavily colored are very rare and are of higher value for example.

There are various cuts available, determining shape and brilliance, but the most popular choices tend to be the princess cut pink diamond, marquis cuts, and round cuts. Your diamonds clarity refers to its inclusion of any flaws, cracks, or cloudiness.

Taking Care of Your Pink Diamond Ring

Executive Summary about Pink Diamond Rings by Dirk Rendel

A pink diamond ring, like most of the other rings that use colored diamonds, can be very beautiful and dear to the person who wears it. These diamonds are pretty rare and only available in certain parts of the world.

Not only is it important for you to clean the diamond properly, but you also need to do it without causing damage to the diamond (like scratches) or loosen up the setting of the diamond.

The very first thing to note that you must store these rings away properly. Use a soft cotton pouch or a cloth to store the ring, and then place it in the box it came in.

Don’t use just any cream or soap to clean your pink diamond. Don’t even go for the sprays and other solutions that are not specifically made to clean diamond rings.  This may result in the formation if an unwanted layer of sediments or a coating of chemicals on the pink diamond, even after you have tried to clean the diamond with utmost care.

For the best results, take your pink diamond ring to the jeweler and get expert advice on cleaning and maintenance to ensure your ring stays safe and looks great at all times.
