Are diamonds really rare? Myths and misconceptions about diamonds
Diamonds are our most popular gemstone. That hasn’t always been the case. It was only in the the last century that diamonds became regularly available. Prior to that, rubies and sapphires were the most popular gems, especially for engagement rings.

The popularity of diamonds is due primarily to the DeBeers organization. They set up the first large scale diamond mines in South Africa. Then they began one of the most successful advertising campaigns in history, convincing consumers that engagement rings should have a diamond.

With proper encouragement, the movie industry displayed their most glamorous women, draped in diamonds. They soon became a top status symbol for the rich and famous. This peaked with the Marilyn Monroe movie, Diamonds are a Girl’s Best Friend.

Even after winning the consumers’ admiration, DeBeers continued their advertising. With the discovery of diamonds in the Soviet Union, a new campaign was created to sell anniversary bands. These made good use of the small, but nice quality diamonds the Soviet Union produced.


DeBeers actually mined considerably more rough diamonds than they sold and they have a large warehouse of uncut diamonds in London.While they have done wonderful things for the diamond industry, not everything about DeBeers is nice. As diamonds were discovered in other parts of Africa and South America, DeBeers managed to get control of the rough diamond supply. The tactics used to gain control of these rough diamond supplies are alleged to include murder and kidnapping.

DeBeers maintained monopolistic control of the diamond market for several decades. They carefully released only enough rough for current demand, while continually adjusting the degree to which the rough was made available.  This caused continually escalating prices, and of course, it increased the perception of rarity. DeBeers actually mined considerably more rough diamonds than they sold and they have a large warehouse of uncut diamonds in London. As a result, they were not allowed to do business in the US, Canada, and a few other countries.

In the last couple decades of the 20th century, things began to change. Satellite technology, that was designed to find likely oil reserves, also showed the geology likely to hold diamonds. As a result, new discoveries began to multiply. Australia was one of the first developed nations to discover major diamond resources. DeBeers was able to make a deal with them to distribute all the rough, except for the very rare pink diamonds.

They also made a deal with the Soviet Union to distribute their rough diamonds. However, shortly after the break up, the Russians let their contract expire and began to sell the diamonds themselves.

The latest major diamond reserve was found in Canada. DeBeers could not make a deal with the Canadians, who are cutting and selling the stones themselves.

It is difficult to tell what the future will hold. Several sites are being explored and it is likely more diamond deposits will be found in the near future. DeBeers still controls approximately 75% to 80% of the diamond rough. The other suppliers have so far been content to sell at the same prices as DeBeers. However, if the law of supply and demand ever catches up to the diamond market, prices are likely to drop considerably. It is difficult to tell how this would play out, but DeBeers has a large inventory of uncut diamonds and would be in an excellent position for a price war.

Myths and Misconceptions
Here are some popular myths that you need to be aware of.

MYTH: Diamonds are rare.
Diamonds are the hardest material found on earth. Other than that, they hold no unique distinctions.  All gem grade materials are rare, composing just a tiny fraction of the earth. However, among gems, diamonds are actually the most common. If you doubt this ask yourself; “How many women do you know that do not own at least one diamond?” Now ask the same question about other gems.


In the constellation Centaurus, there lies a white dwarf, that has crystallized into a diamond 2,500 miles in diameter and weighing 10 billion, trillion, trillion carats.While we are still learning about the interior of the earth, current information shows that diamonds are likely the most common gem in nature. (See Gem Formation in our Reference Library.)

Outside the earth, diamonds are also common. A recent discovery shows that some stars collapse on themselves, creating giant diamond crystals. In the constellation Centaurus,  there lies a white dwarf, that has crystallized into a diamond 2,500 miles in diameter and weighing 10 billion, trillion, trillion carats.

MYTH: Diamonds are the most valuable gem.
You cannot say that one species of gem is the most valuable. To do a comparison, you need to judge gems according to size and quality.  This chart is based on top quality gems in different sizes. However, note that pure red rubies are so rare there is no trade data available. The prices listed are for Burmese rubies.

Species ˝ carat 1 carat >1 carats
Diamond $4,300/ct $13,600/ct $44,500/ct
Ruby $5,050/ct $9,500/ct $100,000/ct
Emerald $5,470/ct $9,030/ct $23,000/ct
Sapphire $10,000/ct $16,000/ct $34,000/ct
Alexandrite $3,600/ct $15,000/ct $1,000,000/ct

As you can see, diamonds are very costly, but not the most expensive gem in any size. If you were to do a comparison of other qualities, the results would be similar.  If you are looking to invest in gems you should read our article on the inner workings of the gem trade.

MYTH: Diamonds are precious.

Elongated, Cut-Cornered Barion Triangle Cut Tsavorite Garnet by Daniel Stair
Precious means valuable. In the 18th century a French jeweler began describing gems as either precious or semiprecious. The categories are still used in merchandising, but are frowned upon by professionals as they are nearly meaningless distinctions.

For example, garnets are considered semiprecious, but tsavorite garnets have sold for as much as $10,000 per carat. That seems pretty “precious” to me!

On the other hand, diamonds are only very valuable in their better grades and medium to large sizes. Small, low quality diamonds are available in quantity for just $1 a piece. A quick search of eBay and you will find several diamonds under $20. These are far from precious.

MYTH: Diamonds are the most brilliant gemstone.

Not counting synthetics, there are at least 15 minerals with a higher refractive index than diamond!Brilliance is determined by the cutting and the refractive index of the material. Diamonds have a very high refractive index of 2.41. Diamonds have the potential, if properly cut, to be exceptionally brilliant. However, this is nothing compared to the 2.9 RI of rutile. Not counting synthetics, there are at least 15 minerals with a higher refractive index than diamond!

MYTH: A person can make a lot of money selling diamonds.
As the Internet has continued to proliferate and GIA has established well accepted grading standards for diamonds, margins on cut diamonds have continued to be thin.

MYTH: Diamonds have more “fire” than any other gemstone.
Diamonds are know for their fire, or dispersion. This is the ability to separate white light into the color of the rainbow. Diamond has a dispersion of .044, which is quite high. However, it is a far cry from gems like rutile with a dispersion of .330!

What is a Diamond?

Colorless and native to New York, Herkimer diamonds are fun to find.
Diamonds are a natural mineral and they are also produced in the laboratory. Lab made diamonds are primarily used as abrasives, but they are beginning to make their way into the jewelry industry. (See Understanding Gem Synthetics and Identification of Synthetic Diamonds in our Reference Library.)

Gemologically speaking, diamonds are a mineral with a chemical composition of C, (carbon,) that crystallize in the isometric system. (See How Gems Are Classified in our Reference Library.)

With a hardness of 10, diamonds are the hardest substance in nature. Harder substances have been created in the laboratory, but they are extremely brittle and have no practical use. If a harder substance is ever found that does not break down so quickly, it will greatly reduce the time need to cut diamonds.

Diamonds have a refractive index of 2.41, which is very high. Being as they form in the isometric system, they do not have any birefringence or pleochroism. They have a specific gravity of 3.51 to 3.53, which is a bit more than average.

hope they figuer out a way to charge the guy with manslaughter, as the woman is for all intensive purpuses dead.

$200? they are doing it wrong, i think that oen gilr got what? $200k? for hers it made a big headline a while ago i linkyed it. i think a male of the same age got all of $2. becuse no oen cares about you silyl males (agys being bad on a very suriues subject ^_^).

on a more seuires note, shame that those young girls are forced into it becuse of money issues. tho even then not all are forced in, a lot do it willingly, some are there parents making the desision for them. nutty place.



My point has finally been made ^_^ (viva la Agy!)

anywho

Under construction ^_^! (probably something spring/Doom Bee related XD) ^_^

trying that new way of quotiing for you criag ^_^, hope it worked ^_^

I do not support leftism, nor did I say anywhere that I did? Its amazing that you think you can assume that I am a leftist. I am simply stating that being a leftist doesn't necessarily make someone a bad person. Next time, please read what I wrote.

Or, at least, I would be saying that, if there was a next time. Once again, I am finished with your mindless chatter. Have fun spamming links and spitting anti-leftist comments.

Agy: by not denoucing it your supporting it. please use brain function next time ^_^

Agy: running away already?  also why you support leftisum again? ^_^

its more complicated then that. we all know the fun of me trying to exspalin things but here I go ^_^
not sure how to exsaplin this with out sounding like a loon (more so then I already do ^_^).
but it falls back to what I said before about if your not fighting for god and country then your fighting for the state. sure you can say its for your country men but that's still the state. my issue is that that's how the Nazis and communists fought, they fought for the state. we all know where the Nazis and commies fall on the big old spectrim of "evil". I worry that its all just one more drop in the bucket that's pushing us closer to the far left of facsisum and communisum. if I were to join I would feel a lot better knowing the person next to me fights for a god, rather then another person who fights for statesman blah. I know that sounds utterly silly and I know I did a terrible job exspalining it. but hopfuly your getting an idea of where I was going ^_^

For me, Country and Countrymen has little to do with the State. For me, Country and Countrymen is all the people and things I love about my country and would want to protect.

tolerance is support.
thats liek saying the germans who knew the concentration camps were going on over the hills wenrt supporting it becuse they were just toloerating it.
thats liek saying the mom who lets her duaghter get raped by her husban isint supporting it becuse she just tolorates it.
thats liek saying the palatine who lets humas fire rockets form there home isint suproting the rockets being fired becuse they are just tolorating it.
thats liek saying the inn owner isint supporting the underage sex ring going on it there inn becuse they just tolorate it.
and so on.
tolorance is support.

I see. And fighting for God is not a slippery slope.
