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.

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.
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.

In practice I wouldn't pay much for this sort of thing, but I dare say
there are people who would; My mother has a crystal vase about six
inches high, just big enough to hold a single rose. I think it would be
quite nice to have one made of a single, perfectly clear, diamond. Move
over De Beers; here comes Swarovski!
