Heh!  Diamonds that are so close to the real thing that it takes a machine to tell them apart yet they're 1/10 the price?  They can call them Wal-Mart diamonds.  Hell, they're cheap enough to *sell* at Wal-Mart.

Still, De Beers says that its move isn't to disrupt existing lab-diamond producers, but create a small, profitable business in its own right.

De Beers is so adamant that the man-made diamonds are not competing with mined stones that it will not grade them in the traditional way.


You heard it here.  De Beers is not redefining the entire industry to drive its competition out of existence.  And if there's one company known world-wide for its ethical business practices, it's De Beers.

This smells like desperation to me.  And while DeBeers is going to etch lab grown diamonds with a trademark, others will not.  Their monopoly is getting broken up, one way or another.

Diamond should be used as an abrasive and nothing else.  The "precious" metal and gem market  needs to shrivel up and die but people are too ignorant and vain to stop wasting their money.

Is it ironic that, had De Beers acted ethically all these previous years, they could have traded on their name as a trusted, internationally known company and perhaps continued to survive and even thrive despite losing their competitive advantages? It feels like that meets the definition of irony, but I always get confused on this point.

Moissanite is superior to not only cubic zirconium but even diamond itself in every way except for hardness (resistance to scratchng), and even then not by much (Mohs 9¼ vs. 8½ for CZ and 10 for diamond). It's tougher than diamond, too, in both fragility (resistance to impact ― diamonds shatter easily and don't make good armor no matter what certain Marvel Comics mutants do) and heat resistance (ditto: they're flammable if there's enough heat and oxygen around, being carbon, and even without actually catching fire).

Manufactured diamonds *are* the real thing, only without the flaws.  I'm guessing that DeBeers is making them in an effort to pretend that manufacturing costs are cheaper (and thus less worthy) than mining.  In reality, diamonds are relatively common, only in places that weren't always known/accessible until the 20th century when DeBeers set up its cartel.

I got my wife a Moissanite engagement ring, set in a palladium band. It was 15% of the price of an equivalently sized diamond, and it looks frickin blingin.

Hated that line. No real jeweler would say that. Moissanite isn't fake diamond like cubic zirconium is. It doesn't try to pretend to be diamond like cubic zirconium does. It's a separate gemstone in its own right, with its own appearance.

It does have to be synthesized since, while silicon carbide crystals do occur naturally, they only do so in asteroid impact craters like the one in Arizona (where Moissanite was discovered by a geologist named Moisson [so why isn't it spelled "Moissonite"?]), and there are no known naturally occurring crystals large enough to form a useful gemstone.

It has more brilliance and fire than diamond. It's also double refractive (diamond and most other gemstones including CZ are single refractive) which changes the effect as the gemstone rotates relative to a light source and the angle of view, so it becomes quite obvious that it's not diamond which has a different effect as it rotates.

It's also less dense, so one carat of Moissanite makes a noticeably bigger gemstone than a one-carat diamond. Though I believe these days it's mostly sold by mm radius, not carat weight.

There is one other crystal that can be synthesized into gemstones (which also occurs naturally but not in crystals big enough to form a gemstone, so the gems made from it are synthetic) that has even more fire than Moissanite, and not by a little bit, either. It's by far the most fiery crystalline substance I know of: strontium titanate (dispersion of 0.190 vs. 0.104 for Moissanite, 0.06 for CZ, and only 0.044 for diamond), if not as brilliant (IOR of 2.41 vs. 2.417 for diamond, only 2.2 for CZ, but a whopping 2.66 for Moissanite). It had some popularity in the mid-to-late 20th Century, but it has one serious downside: its Mohs hardness is only 5½, making it way too easy to scratch or chip. It would look nice as earrings or some such that wouldn't be likely to be scratched or chipped.

You should always wait until *after* the wedding.

I bought an engagement ring once.  Spent way too much.  Had it thrown at me several times.  After the third time, I just kept it and called off the engagement.  If anyone wants a 7-year old, slightly abused engagement ring with a bad omen attached to it, let me know.

Didn't have to, she picked it out. She wanted a "space rock".

If you think they're 1/10 the price, you probably fell for a site selling things that were not synthetic diamonds. I priced out a nice stone at the Diamond Foundry (the article mentions that they are a large scale producer of synthetics). It's princess cut, 1.04 carat, H color, VS2 clarity, ideal cut. The sort of stone a fairly well-to-do future husband might buy. $4223.

OK, what does a comparable mined gem cost? Head over to Blue Nile and price out a gem with the same stats. $5467. That ~$1200 difference is certainly not nothing, but 77% is also certainly not 10%.

Another weird lie people are willing to believe is that manufactured diamonds are perfect. If they were, why would Diamond Foundry advertise that stone as VS2 clarity? A "perfect" diamond, which would be a full 5 gradations higher on the clarity scale, could certainly fetch a higher price. Why would they lie and tell you it has inclusions?
