OMG!!! Are these Rocket Scientists???
Real Genuine Synthetic Diamonds, Who would'a thunk.
cue the vikings
It's my suspicion that when the patents run out, around
15-20 years from now, the price of diamonds will finally
fall to a realistic level, and deBeers will pack up shop.

People have been making diamonds in laboratories for more
than fifty years. The basic patents have long since run
out, and the price of diamonds remains high.
Three reasons. First, even the most recent, still-patented
techniques, cannot practically duplicate top-end natural
gem-quality diamons. The one-carat blue-white "flawless",
which is essentially the benchmark of the industry, is
still somthing you have to hunt for in a mine. Or you
can have one made in a laboratory as a stunt, but you
can't have them mass-produced for sale with any technology
we know of.
Second, people don't *want* synthetic diamond gemstones.
The ones who might have wanted such a thing, have long
since moved on to cubic zirconia or whatever; the ones
who are still buying mediocre half-carat diamonds of the
sort that can be mass-produced in a factory, want them
not for what they intrinsically are but for what they
represent - the closest thing people on a budget can
get to the archetypal one-carat blue-white flawless.
Which is to say, among other things, natural and mined.
Third, the techniques for producing synthetic diamond,
are not themselves cheap. Well, industrial abrasive
diamond, yes, sort of, but not any sort of synthetic gem
diamond. Some of them are pure laboratory curiosities
of no practical or economic significance; others can be
industrialized, but you're not going to be seeing the
output at your local 99-cent store any time soon.

synthetic diamonds is maximized by restricting supply.

Not really, no. DeBeers has long since lost its monopoly
in the field; the Australians and Canadians and Russians
provide most of the world's gem diamonds now and each will
gladly fill any supply shortfall the others might try to
create.
The profitability of both natural and synthetic diamonds
is for the most part maximized by increasing demand, by
means of some rather noteworthy and successful advertising
campaigns.
You might still be able to arrange cheap diamonds, but by
definition nobody will care.

Mmmmmmmmmmmmmm
Well equipment can tell them apart!
What is interesting is that deBeers gave Jewelers in Australia free
special equipment to tell them apart because most Jewelers could not
tell them apart!

That is for sure. The Russians are apparently sitting on a fortune of
diamonds and not selling them for that reason.

Chromatic aberration might be a problem.
Even so, based upon posts here, people will be complaining about thick
lenses and want lighter ones as well.

I kind of doubt it. A lot of people who want diamonds for jewelry want
them because they're expensive, not because they're just diamonds. All
De Beers has to do is keep pumping the idea that their diamonds are what
the consumers want and artificial diamonds are fake, regardless of
whether they're indistinguishable. De Beers already has methods of
tracking the authenticity of their diamonds, so whether you can't tell
them apart is really irrelevant in that respect.
Diamonds for industrial purposes is another thing, but there already De
Beers doesn't have a lock on that market.

In addition: suppose you have a small start-up company that produces
diamond in large crystals. Do you try to compete in an established
market of luxury baubles already dominated by De Beers, or do you
target the market for high temperature semiconductors, radiation
detectors, and lasers which is currently wide open? The later requires
moderately priced materials that can compete with silicon, silicon
carbide, and Nd:YAG. I know I'd try to make my fortune by touting my
product as a superior material for technological applications, and if
flooding the jewelry market with inexpensive diamonds was a by-product
of this, then so much the better.

Diamonds also come in various colors and clarities. Gem quality diamonds (as
opposed to industrial diamonds) are not cost effective to make in a
laboratory. |

To All:
Diamond material has been created for a long time. Diamond
particles have been created for grinding and polishing compounds for
years. Diamond coatings for thermal transfer for say heat sinks
attached to micropocessors has been available of the shelf. Creating
diamond optically clear films or windows, lenses is around. The problem
is if you look is that De Beers owns the patents on any diamond
material that is considered optically transparent (any wavelenght not
specified in patent) above a certian thickness. Figure out away around
that and you can create your gems in a vacuum chamber fairly simply.
You include what ever impurities you want (a lot of analysis of these
has been done over the years and is in papers) and you would have a
very hard time telling the real from the newly created diamond.

Bill and Salmon Egg,
Diamond lense are already here about $1700 each and the
company Sixth Element is making them, wild quess who owns them. Thats
right the De Beers, here is a site with a PDF file talking about them.
By the way Intel also uses a lense version for IC analysis on the new
emmi instruments. Enjoy.
