Now that man-made, or synthetic diamonds are so common, it's good to
distinguish them from the artificial stones that only *look* like
diamonds. The synthetics, again, are real diamonds. They can even make
some gem-quality synthetic diamonds today.

Here's an interesting article about synthetic vapor-deposition diamonds:
http://www.newscientist.com/article/...tra-large.html

They are producing gem quality up to 34 carat! With an improved process
that will allow much larger "... to kilocarat diamonds of high optical
quality". De Beers must be having nightmares!

Wow! DeBeers, the ballgame is about over.


Astonishingly: " ...600 tonnes of synthetic diamonds are produced each
year for industrial use alone ..."

Bob

Yeah, that volume has been climbing, and products like diamond hones are
getting to be pretty common.
