Possibly a good time to plug moissanite yet again: http://diamondssuck.com

If you ever want a proof that the market can be utterly irrational, look no further than: > The arrival of lab-grown diamonds has challenged the widely-held assumption that diamond prices could only go up
As the price of diamond continues dropping, I wonder if people will find more interesting applications of the material and it'll eventually become as mundane as things like steel and aluminium. Besides its hardness, it also has very high thermal conductivity. Diamond is still too expensive to be a bulk material, but I look forward to when things like this become cheap and commonplace: https://en.wikipedia.org/wiki/Fi…
Inexpensive mass production moved it from niche prestige uses to unlock its many utilitarian applications.
> De Beers fights fakes with technology as China’s lab-grown diamonds threaten viability of the real gems From what I understand, these gems are actually better than natural ones, since they're 100% pure. Maybe it's time to call lab-grown diamonds "real" and mined ones "fake".
There was a similar problem with Rubies and they detected the fakes by virtue of the fact that they were flawless.

They’re called fake because they’re artificial, not because they have more flaws. The diamond industry might have once thought it could rely on artificial diamonds being less perfect, but it’s under no such illusion now. I think it’s fair to acknowledge that, even if we don’t like it, many people prefer natural diamonds because they’re natural, not because they believe they’re somehow more “pure.” In other words, I b…

I also highly recommend Edward Epstein's Atlantic article on this too: https://www.theatlantic.com/magazine/archive/1982/02/have-yo... One of the best pieces of long-form journalism ever published, without a doubt.
Earlier quoted context omitted.
>> From what I understand, these gems are actually better than natural ones... Yes, for decades they claimed clarity and purity to be indicators of the highest quality. Now that humans can manufacture them with better specs than nature, they're shifting to claim that "natural" is better. In the end it's a pretty carbon lattice.
In that respect it's the same as any other collectible or antique that can be reliably replicated in slightly better condition and with slightly less irregularity than the highly prized "mint condition" originals made by the most skilled artisans... (Less so for industrial uses, or for inserts into the average person's engagement rings where it's the thought and style rather than the provenance that counts)

Cubic zirconia looks identical to diamonds but it's not chemically the same so people always considered it fake. Synthetic diamonds are chemically identical so De Beers need to invest millions in figuring out ways to distinguish them. Natural diamonds don't add anything more, but the whole purpose of them is that they're expensive.
