I'm not sure if this article refers to cubic zirconia, moissanite or some new flavour of human-made diamonds but in either case, this is has been going on for 40 years.

The market for diamonds isn't rational, so how it will behave is not predictable.

First, the idea that diamonds maintain value is nonsense. This isn't gold or some other mineral "currency." You can sell gold anywhere for close to its spot price. Diamonds OTOH, have buy-sell "spreads" more like antiques or collectible shoes.

So, the subtitle is already on the wrong path. Diamonds have never been good stores of wealth, that's why the earlier dowry traditions use gold, cattle, secret recipes or some other reliable asset.

With cubic zirconia & moissanite, the diamond industry learned to recognise the "fakes." They've had machines for a while, but the industry also invested a lot in jeweler training. The reason for this is perception. If only machines know the difference...

For the average buyer, they're encouraged to note differences in "brilliance" & "fire" which is kind of visible in certain light. Ironically, zirconia & moissanite are different from diamonds in opposite ways, one more and the other less fiery.

This is a pure pr fight. If people use terms like "fake diamonds" then de beers wins. "Blood diamonds," then they lose.

Curious side note: the CCP has influence on Chinese consumer culture that doesn't exist elsewhere. If they say manufactured diamonds are real, then they are. China doesn't mine diamonds, but they do manufacture them....




Replying to myself with a conspiracy minded thought....

Now that I think of it, De Beers probably has a strong interest in "fraud" being a problem. If manufactured diamonds are sold as natural, this is fraud. There will be victims, trials, fraud prevention... All good reinforcement that these things, they're not really diamonds. Fake is debatable. Fraud is something that you can get a judge to say.

So, back toy initial question. What is this article talking about? Is this a new type of gem, or the ones that have already been available for decades. If not...


Synthetic diamonds are exactly that. Not cubic zirconia.


The article is definitely not about cubic zirconia or moissanite, which are easier to distinguish. You don't need special machines for that.
