Lab Created Diamonds Come to Market

E writes "Technology is putting some new sparkle in the world of diamonds. Until recently, naturally occurring, mined diamonds were unchallenged in their quality and desirability. But now laboratory-created diamonds, which possess the same properties as naturals, are poised to give them a run for their money. A new company, Adia Diamonds, has quite the variety in their inventory. They have the same chemical and physical properties as a mined diamond and come in white, blue and yellow. Both GIA and EGL grading labs are offering certifications for lab created diamonds. Seems like a good, high-tech alternative to the DeBeers diamond cartel."

    The article hints more at the new synthetic process' value for jewelry, but I'm not so certain that most jewelers will appreciate it -- especially the jewelers that cater to the most extravagent tastes. Diamonds have always been an oddity for me -- I understand the diamond's purpose in industrial applications (drill bits, saw blades, abrasives, and even in semiconductors) but the De Beers Group situation is not one I've ever understood -- even when trying to "think like a lady."

    I'm guessing the De Beers Group isn't worried about these synthetic diamonds, either -- they have such a great relationship with most jewelers because the De Beers Group spends a LOT of money in how they market the diamonds: marketing that provides diamonds for the bling-bling rappers, the royal families, the Hollywood stars and whoever else needs something sparkling to wear in public. That's what the jewelers want: they don't care if it's cheap, they get a great marketing campaign and still make huge profit margins.

    From Adia's website, we see only one retailer that resells their diamonds. Here's a company that has been around a few years, and they don't have a lot of support.

    For industrial applications, though, is the De Beers Group really a powerhouse? I'd always heard that a lot of flawed diamonds end up in the industrial applications, and the flawed ones are significantly cheaper than the "perfect" clarity versions used in jewelry.

    As a sidenote, my lady doesn't wear diamonds unless they're family heirlooms -- I've gotten her to move to 22K and 24K gold jewelry. It is shiny, sparkles like crazy if cut right, and when it wears down, I have it swapped for a new piece of jewelry in any Indian neighborhood (or in India) for a relatively competitive price. Diamonds are sort of boring for her now -- she sees how little they store value over time versus gold, and they're not very useful in a financial emergency (versus gold or platinum). Plus the fact that she can "trade-up" her softened jewelry for something else really captivates her -- the last ring she wore we "exchanged" for a set of earrings that was traded for bangles a few years later. With the diamond, she's mostly stuck.

When CZ first hit the market, jewelers really flipped out, because people could buy diamond rings, replace the diamond with CZ, and then return the ring with the CZ for full price. At first, the only surefire test was to measure the density, but that required removing the stone from the setting, something that takes some time. The company that created CZ then also produced a tester which at its tip had a small heater and a temperature probe a little ways away. If you touch the tip to a diamond, heat will transfer from the heater to the probe, whereas with a CZ, it will not. The company made more money off the patent for the detector than they ever did off CZ.

It is a form of silicon carbide, and it actually has a higher index of refraction than diamond (it sparkles more). It also has a high thermal conductivity, so it would fool the old testers.

The most advanced people at making artificial diamonds was a lab in Russia.

      As far as I can remember the main problem they were encountering was Nitrogen. In a natural diamond which forms over a long period of time the nitrogen atoms would drift together over time and end up clumped together and form a seperate molecule (N4) of pure nitrogen embeded in the carbon lattice. This nitrogen molecule absorbed some light from the carbon but was otherwise undetectable.

      In the early attempts at making artificial diamonds they left the nitrogen in but it did not migrate together so ended up actually part of the carbon lattice. This gave the artificial diamonds a slight yellow tint as the nitrogen also emitted light back into the diamond crystal lattice. The Russian solution was to remove all the nitrogen at the start of the process.

      This produced perfect, pure carbon diamonds with a perfect crystal lattice. These diamonds however had a the property of trapping light so that when the light falling on them ceased (you switched the light off) they fluoresced, giving off the light they had been trapping with in the crystal lattice due to total internal reflection. Now this may have made them really cool but it did make them different to naturally occuring diamond.

      What the Russian team really needed was a way to leave in the Nitrogen impurity but so that it did not ever interupt the carbon crystal lattice.

      At this point De Beers was already shitting themselves and started looking at ways of marking there diamonds to prove they were mined diamonds not some knocked up in a lab. They semed to have a number of ideas such as laser etching the DeBeers trademark on each stone and similar but I dont know what the ultimately chose.

Boron doped diamond creates a 'p' type semiconductor, but I don't believe there is a well accepted method of producing an 'n' type semiconductor essential for a computer chip (perhaps someone here could enlighten us on this?).

Diamond has a thermal conductivity of about 1000 W/m K while silver has a thermal conductivity of about 406.0 W/m K.

    Grown synthetics were still experimental when Wired wrote their article, but that's the more promising process. Those, in theory, can be indistinguishable from natural ones.

    The diamond industry had painted itself into a corner with the concept that the most valuable diamonds are "flawless". You do not want to be in that marketing position when going up against the technology that makes semiconductor wafers. Look for PR about how real diamonds have "natural flaws".

    Tied to this is the "Kimberly Process", the agreement supposedly intended to restrict the flow of conflict diamonds. This requires source documentation to travel along with diamonds as they pass through the distribution chain. Previously, diamonds were generic; nobody cared where they came from. The Kimberly Process has the effect of making it much harder to insert large quantities of synthetic diamonds into the distribution system.

    first of all, jewelers don't make a "huge profit margin" on diamonds, in fact they generally make very little, unless you walk in there waving a huge wad of cash. there is a very well known document called the "rap sheet" (aka rappaport sheet) which is published weekly and lists the wholesale prices for various grades and types of diamonds. if you know even a little, you can get a jeweler to give you 5% over rap, which is hardly a huge margin compared to media/software/drug companies.

    secondly, diamonds are definitely an item for which you get what you pay for. can you overpay? absolutely. but a $5000 diamond from a good retailer (like whiteflash or blue nile) is going to be twice as good as a $2500 diamond when it comes to the all-important flashyness factor (amount of light returned through the top of the stone) also, any good retailer will buy your diamond back for what you paid for it originally if you want to trade up (like the gold guy)
