Dr Fred MosselmansDiamond is capable of studying a huge variety of samples from every discipline of scientific research. Dr Fred Mosselmans, Principal Beamline Scientist for Diamond's microfocus spectroscopy beamline, says, ‘In the past year, example of samples studied have included wood chips from the Mary Rose warship, paint pigment samples from Tate Britain, brain tissue to further our understanding of Parkinson's disease, metal on metal hip replacements, stainless steel corrosion and the comet grains from the Stardust mission – a reflection of the huge breadth of research undertaken at Diamond.’
The University of Leicester team plan to study more cometary tracks at Diamond in the months to come, from which they will be able to establish accurate comparisons with meteorites and determine the processes – such as liquid water in the nucleus and mixing in material from the hot inner Solar System – that have gone towards forming comets.
Researchers can contact scientists to discuss their experiment ideas and then put a proposal together for beamtime. An international scientific review panel considers all proposals before allocating time on one of our beamlines. Diamond currently has 11 operating beamlines, with a further 11 being added between now and 2012.

A comet’s tale at Diamond

A cometary track in aerogel analysed at Diamond 2mm acrossA new picture of the composition of comets is emerging with the help of 21st century technology available at Diamond, the UK’s national synchrotron light source, in Oxfordshire.
We already know that comets played a significant role in ensuring that conditions were right for life on Earth. Most of the icy, small planetary bodies that otherwise became comets went into forming the gas giant planets in the outer Solar System but some were ejected from the vicinity of the largest planets. Of these, a fraction ended up in the inner Solar System bringing water and biogenic elements of interest to Earth. Without this cometary transport, life on Earth may never have had a chance to start.
Now, scientists from the Space Research Centre at the University of Leicester have, for the first time, brought samples of the Comet Wild-2 to Diamond. In doing so, using Diamond’s microfocus spectroscopy capabilities – bright and powerful X-rays with a beam size equivalent to one 25th of a human hair – they have discovered that the old model of comets as dusty iceballs is not the whole picture.
Dr John Bridges, from the Space Research Centre, explains the results, ‘Comets are starting to look a lot more complicated than the old dusty iceball idea. For one thing Wild-2 contains material, like chromium oxides, from the hot inner Solar System – so how did that material get mixed in with a comet which has spent most of its life beyond Neptune? It suggests that there has been major mixing of material from inner and outer parts of the Solar System in its earliest stages.
‘At Diamond, we have also been finding X-ray signatures of iron oxides. These are important because they show that on the Wild-2 nucleus there could have been small trickles of water that deposited these minerals. Similar grains are found in carbonaceous chondrite meteorites. This might mean that there have been localised heating events perhaps caused by impact on the Wild-2 nucleus that melted some of its ice.’
Their samples, which were born in the Kuiper Belt near Neptune, were collected by the Stardust space mission, which involved a seven year long, five billion km, journey. They then travelled by more conventional means (Fedex) from the US to the Space Research Centre. The Stardust mission was conceived so that comets could be studied directly as this will help researchers to find out more about the Solar System’s water and the dust that escaped planetary formation.
Dr Bridges adds, ‘It’s now becoming clear that not all comets are the same. For instance, Wild-2 may have more similarities to some asteroids and primitive meteorites than comets from the Oort Cloud, which extends to the outer limits of our Solar System and which are infrequent visitors to Earth.’

New vs. Old Diamonds

name David W.status otherage 30sQuestion - I recently saw a show on gemstone quality syntheticdiamond manufacturers and what companies like DeBeers are doing to detectthem. Basically, the research at DeBeers currently focuses on detectionof nitrogen trapped in the diamond matrix with spectroscopy. Since theatmosphere is mostly nitrogen all diamonds contain some as they areformed. Natural diamonds have had "millions" of years to leach off anytrapped nitrogen and contain almost none. DeBeers concludes that theirsystem of counterfeit detection is nearly foolproof and "obviously"synthetic diamond manufacturers do not have millions of years to wait fortheir product to mature.My question is:Why couldn't a company that has already spent millions for hydraulicpresses spend a few thousand more to eliminate the nitrogen? If theyprecipitated the graphite out of a nitrogen free solution and thenprocessed the stones in a vacuum chamber they could completely eliminateall nitrogen from their stones. This seems to be the obvious next step--Iassume if it would work someone would have already done it, so why wouldit not work?------------------------------------------------Eventually I think the market will make the call...if you remember "culturedpearls" were not at first accepted, but their beauty made the finaldecision...as will the diamonds.Peter Faletra Ph.D.Assistant DirectorScience EducationOffice of ScienceDepartment of Energy=========================================================Hi,As you know, diamond making process is rather difficult and complicated: simulating what it took nature millions of years to accomplish in under 100 hours. But the work is continuing and I expect that we will have real (synthetic) diamond of any desired quality and color in not too distant future. Size is quite another problem.But in response to your question, there are ways to produce diamonds without the yellow color. The yellow color is due to ATOMIC nitrogen dispersed in the diamond. Mined diamond (note that I do not use the term natural diamond) often has nitrogen but the atoms of nitrogen have coalesced rendering the diamond colorless.That fact points the way to an approach to make the yellow color go away: by forcing nitrogen atoms to combine. This has been partially successful: by heating diamond over a long time, the yellow color has been reduced. But this is a lengthy and as-yet incomplete process.The other technique that has been used successfully is to use a"getter" (a material that attracts nitrogen) when making diamond. Aluminum is one such material and by using it colorless diamonds have been produced in Russia.A third option, as you correctly noted, is to grow diamond in a nitrogen-starved environment. It does not have to be vacuum, however.I do not know the practical difficulties with this approach but given the high pressure high temperature environment one operates in, it may be presently uneconomical. I think when assembly-line type production facilities come about, the issue will be properly addressed.One final point about diamonds in general. Diamond as a high-priced luxury item is one of the largest marketing gimmick created by man.Behind all this is a very powerful cartel, unregulated and supernational. It controls the market by controlling the mines, supplies, and distribution channels. That there are no major or potential alternative suppliers or competitors speaks for itself. I do not know of any other commodity (and yes, despite advertisements to the contrary, diamond is a commodity) controlled by one single company worldwide. The problem it faces now is how to maintain its monopoly by convincing the unsuspecting public that diamond is not diamond unless it is mined. The situation is perhaps similar to the days where hybrid /engineered plant seeds were considered fake, unnatural, synthetic.There is no doubt that REAL diamond (ones with perfect and specific crystal structure, specific impurity, color, etc.) will be the ones grown by man in factories in the next few years. All the proposed detection techniques to determine if the origin of a diamond is a mine or a factory misleads the public. Indeed, if what is great about diamond is its beauty (and from a consumers' point of view it is), why would one care about its source? The attempt presently is to perpetuate the false notion that diamond from ore has an investment aspect to it.It does not because if the market were open and free competition would take off, prices would collapse, and diamond for the most part would be treated like other stones. It is an irony that the artificially high price of diamond has fueled the research that will shortly undermine the price structure. Diamond will perhaps be the tulip of the 21st century.Ali Khounsary, PhDArgonne National Laboratory========================================================There are a number (more than 10 at least) ways to "date" minerals usingradioactive decays of minor constituents, or the ratio of various nuclides.This is a very sophisticated science and technology. I am not a gemologist,nor an expert in the dating of minerals, so like you, I am making somereasonable guesses and assumptions.1. I am not sure that companies that make "synthetic diamonds" are targetingthe gem market as a place where their high temperature/pressure technologywould fit. I would think that they would be attracted to the industrial diamondmarket where diamonds are used as grinding media etc. This is much lessdemanding of quality and size diamonds than the gem market.2. Yes, if they were going head-to-head with the gem diamond business, theycould be able to purge the system of N2 or even put the entire machine in avacuum. But their attempt a forgery would be much more complicated. Theywould have to start with fairly "old" graphite because any "new" graphitewould result in diamonds that have much more carbon 14 activity than the"geological" grade.3. Given the lucrative nature of diamond market for companies like DeBeers,I would be very surprised if they do not have a whole battery of chemical andphysical tests for diamond "signatures". I would be very surprised that theywould not be able to tell, not only what country, or part of the world, adiamond originated, but even be able to tell you which mine it came from,and when it was mined. I would be surprised if they did not have a paper trailaccounting for every diamond of significant value -- where it went to fromthe mine, who bought it, how many and what kind of diamonds were cut, wherethese diamond "daughters" then went, and so on.These cartels want to preserve their monopoly, and they have very deeppockets stuffed with lots of cash that a make synthetic diamond makers seemlike paupers. Somewhere in this world DeBeers probably has their ownsynthetic diamond producing facility and know as much as anyone what thepluses and minuses are.This is high stakes business and the "haves" are not going to let the "havenots" into it just because of a few trillion dollars.Vince Calder=========================================================

Chemistry of Diamond

tame' or 'I subdue' or the related word adamas, which means 'hardest steel' or 'hardest substance'. Everyone knows diamonds are hard and beautiful, but did you know a diamond could be the oldest material you might own? While the rock in which diamonds are found may be 50 to 1,600 million years old, the diamonds themselves are approximately 3.3 billion years old. This discrepancy is because the volcanic magma that solidifies into rock where diamonds are found did not create them, but only transported the diamonds from the Earth's mantle to the surface. Diamonds also may be formed under the high pressures and temperatures at the site of meteorite impacts. The diamonds formed during an impact may be relatively 'young', but some meteorites contain star dust, debris from the death of a star, which may include diamond crystals. One such meteorite is known to contain tiny diamonds over 5 billion years old. These diamonds are older than our solar system!
Start with Carbon
Understanding the chemistry of a diamond requires a basic knowledge of the element carbon. A neutral carbon atom has 6 protons and 6 neutrons in its nucleus, balanced by 6 electrons. The electron shell configuration of carbon is 1s22s22p2. Carbon has a valence of 4, since 4 electrons can be accepted to fill the 2p orbital. Diamond is made up of repeating units of carbon atoms joined to four other carbon atoms via the strongest chemical linkage, covalent bonds. Each carbon atom is in a rigid tetrahedral network where it is equidistant from its neighboring carbon atoms. The structural unit of diamond consists of 8 atoms, fundamentally arranged in a cube. This network is very stable and rigid, which is why diamonds are so very hard and have a high melting point.
Virtually all carbon on Earth comes from the stars. Studying the isotopic ratio of the carbon in a diamond makes it possible to trace the history of the carbon. For example, at the earth's surface the ratio of isotopes carbon-12 and carbon-13 is slightly different from that of star dust. Also, certain biological processes actively sort carbon isotopes according to mass, so the isotopic ratio of carbon that has been in living things is different from that of the Earth or the stars. Thus it is known that the carbon for most natural diamonds comes most recently from the mantle, but the carbon for a few diamonds is recycled carbon of microorganisms, formed into diamonds by the earth's crust via plate tectonics. Some minute diamonds that are generated by meteorites are from carbon available at the site of impact; some diamond crystals within meteorites are still fresh from the stars.
Crystal Structure
The crystal structure of a diamond is a face-centered cubic or FCC lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons (triangular prisms). Based on the cubic form and its highly symmetrical arrangement of atoms, diamond crystals can develop into several different shapes, known as 'crystal habits'. The most common crystal habit is the eight-sided octahedron or diamond shape. Diamond crystals can also form cubes, dodecahedra, and combinations of these shapes. Except for two shape classes, these structures are manifestations of the cubic crystal system. One exception is the flat form called a macle, which is really a composite crystal, and the other exception is the class of etched crystals, which have rounded surfaces and may have elongated shapes. Real diamond crystals don't have completely smooth faces, but may have raised or indented triangular growths called 'trigons'. Diamonds have perfect cleavage in four different directions, meaning a diamond will separate neatly along these directions rather than break in a jagged manner. The lines of cleavage result from the diamond crystal having fewer chemical bonds along the plane of its octahedral face than in other directions. Diamond cutters take advantage of lines of cleavage to facet gemstones.
Graphite is only a few electron volts more stable than diamond, but the activation barrier for conversion requires almost as much energy as destroying the entire lattice and rebuilding it. Therefore, once diamond is formed, it will not reconvert back to graphite because the barrier is too high. Diamonds are said to be metastable, since they are kinetically rather than thermodynamically stable. Under the high pressure and temperature conditions needed to form diamond its form is actually more stable than graphite, and so over millions of years carbonaceous deposits may slowly crystallize into diamond.

Investing in Naturally Fancy Colored Diamonds

Worldwide Diamond Brokers is excited to introduce our fabulous new website, Rare Colored Diamonds.com. You are about to view some of the most beautiful and extremely rare fancy colored diamonds available in the world today.
Naturally fancy colored diamonds are the most valuable gemstones on the planet as determined on a price per carat basis. Exceptionally fine colored diamonds have no fixed price - and as with fine paintings, set rules do not apply. Their true value will be determined when they are sold at auction.
Investing in rare colored diamonds is a long-term investment. The economic cycles of the past 15 years has seen colored diamonds reach new heights in value as price records were broken. Twenty years ago a one carat Fancy Intense Internally Flawless Pink Diamond would have sold for approximately $70,000.00 a carat, today that same diamond would be worth $500,000.00. In fact, on November 1995 at Sotheby's Auction House in Geneva a 7.37 carat Fancy Intense Purplish Pink Diamond sold for $819,201 a carat. The highest price ever paid per carat for a colored diamond was $1.3 million per carat. It was a 3.73 carat Fancy Vivid Blue sold at Christies Auction House on May 16, 2008 for $4.95 million. The Rare Colored Diamonds Historical Price Tracking System is the perfect tool for investors to view the potential future value of a rare colored diamond based on the current market trend of a particular type of diamond.

Diamond Size Tutorial

Diamond Size Tutorial
Step three toward finding the right diamond is to learn what size, or carat weight, you can afford.
Here is the fastest and most accurate approach to finding the size of diamond you can afford:Research live prices at a large online diamond database.
I will show you how to do this at one of the largest databases, with about 500,000 diamond listings: Diamond.info. But don't go there yet, stay with me for the step-by-step.
First, prepare two browse windows on your desktop.
For Windows users (it should work on most browsers this way):
Make this window (the one you are reading right now) very narrow, so it only takes up the left half of your computer screen
Click this link to open a new window for the search form at: Diamond.info
Move that window to the right half of your screen.
Now you can read this tutorial on your left, and enter data in the search form on your right. Excellent.
And of course, if you have a small screen, just print this page so you can follow along, then click to open your full window for Diamond.info.
Now you are ready to do your diamond size research.
In the diamond search form:
Select your choice for "Shape"
For now, enter whatever "Carat" weight you want (to get started)
Select your range for Color (ex: "G to H")
Select your range for Clarity (ex: "VS1 to VS2")
Skip "Depth" and "Table" for now
Select "Sort by carat"
Check the box for "descending order"
Click Start Search
Narrow your search until you decide the size of diamond you can afford! One site is enough for this exercise, so let's move on to other issues...
Important:This is only the beginning, and you will be refining your size decision as you learn more about the rest of the quality factors in the next step.
Bit of Advice:The secret is to find a good jeweler you can rely on, for answers to any questions you might have along the way. You might want to start with the tested internet jewelers and the tested local jewelers. Read our reports and make a decision about that first and foremost. If nothing else, they are good benchmarks to compare anyone else you might find on your own. If you have done that, then

Diamond Quality:

Your second step in finding the right diamond is to decide on the basic 4 Cs:
Cut,
Color,
Clarity, and
Carat Weight.
Personal Note to my Readers:[This is probably the most popular page in this tutorial. It helps you make the best decisions in a fraction of the time it would take you on your own, or on any other website I know, for that matter. This one article will teach you everything you need to know (about the basic 4 Cs at least), without wasting time with details you don't need. Most sites try to impress you with their knowledge. Do you have time for that? I prefer to help people get right to the point. Yes I know diamonds, very well indeed, to any detail you care to discuss. But I prefer to make it easy for you, just like I would for my friends, rather than bore you with fancy footwork. If you want all the details, I will be here for you. But if you are like most savvy, busy people, this one article will save you many hours of research and agony. Enjoy!]
Decide on CutThe Cut actually refers to two separate aspects of a diamond's appearance: 1) shape, and 2) quality of workmanship.
===== Shape ===== Popular diamond shapes include Round, Marquise, Princess, Radiant, Pear, Oval, Emerald, and Heart.
Choose two shapes if possible and write them on your checklist. There is only one way to find out what she wants in this regard -- ask her. But if you're sneaky, you can find out by having her best friend ask her discreetly and tell you. Either way, you should definitely find out about this before you buy...because some women are very attached to certain diamond shapes. If you like to live dangerously (though we do not recommend it in this case), you could pick one of the most popular shapes to increase your odds of picking her favorite. The most popular shapes this year in our experience, in order, are: Round brilliant, Princess, EmeraldLearn more about shapes.===== The Make -- Quality of the Cut ===== It is extremely important to learn about the make of a diamond for three reasons: 1) the make varies greatly from one diamond to another2) the make determines over 90% of the beauty of a diamond3) a concise grade for the make is not included on most diamond certificates, including the GIA diamond grading reportIf you want perfection regardless of cost -- go for the Ideal Cut.If you want quality and beauty -- go for very good to excellent make.If you want a larger stone for your money -- go for good make.If you want the lowest grades -- we don't recommend fair to poor makes for engagement rings due to a noticeable lack of brilliance and fire (even when color and clarity are very high).Learn more about diamond makes, and how diamonds are faceted.
We will go into more detail about this in step four: How to Read a Certificate and Go Beyond the 4 Cs.
