graphite that can crack diamonds!
London, Nov 7, 2010 Scientists have shown that when compressed, graphite can
crack a diamond. Now computer simulations by Hui-Tian Wang at Nankai University
in Tianjin, China, and colleagues have shown that the compressed material could
be at least partly made of bct-carbon, which is built up from .. read harder

How
are diamonds formed Comparing the properties of diamonds and graphite
provides clues as to where diamonds originate. Graphite forms close to the
surface of the earth. The fact that diamond’s crystalline structure is more
compact than that of graphite implies that they form in deeper environments
where pressure and temperature is higher. read more about Diamonds

Cosmologically Speaking, Diamonds May Actually Be Forever
If you’ve ever wondered about the ultimate fate of the universe, Lawrence
Krauss and Robert Scherrer have some good news - sort of.
Advanced Diamond Technology lead scientist Mike Moldovan is reflected in
ultrananocrystalline wafers Wednesday as he explains the process used to make
them.
"That's the beauty there really is no difference."

A post-doctoral fellow at McGill University has discovered that diamond
birth may well be forever, but their origins are not necessarily as
clear-cut as commonly believed.

At the headquarters of the Gemological Institute of America, 300 diamond
graders peer into microscopes and ponder gems lined up on light tables. They
work behind man-trap doors - where one door must close completely before another
opens. Security guards scan the floor from nearby stations.

Synthetic diamonds the key ? See you beloved death in a diamond ??
One person can be produced
into 100 diamonds, explains the company's website. According to the website,
LifeGem created Diamonds have the same qualities as those available at
Tiffany's.
Diamonds may be a girl’s best friend, but when it comes to paying for the
pricey sparklers, the boy’s best friend may be Stephen D. Lux.
Lux is a chemical engineer whose company, the Gemesis Corp., turns out
thousands of gem-quality yellow diamonds every month from a factory in Florida,
US. Gem snobs may never go for them. But they’re not fakes—no cheap cubic
zirconias, no moissanites these. Lux is a 21st century alchemist who is turning
pure carbon into real diamonds, squeezing it into sturdy carbon crystals under
intense heat and pressure inside his machines.
'Lab Diamonds' Offer Alternative To Mined Diamonds
Jim Benemann Reporting found Feb 9, 2007 9:55 pm US/Mountain at cbs4denver.com
(CBS4) DENVER The movie "Blood Diamond" has forced
international attention on the conflict and oppression associated with mined
diamonds.
People who want a conflict free diamond have a stunning new alternative, and
it's even a bargain.
The movie profiles the dangerous business of "blood diamonds" in
Africa, and that's made a lot of people think twice about their next piece of
jewelry.
To be absolutely positive a diamond has no connections to conflict, it has to
come from a laboratory.
Fifth Avenue Designs is the first retailer in Colorado to carry lab diamonds,
but only after owner Larry Blauweiss gave the gemstones a second look.
"My first impression was oh, oh here we go with another copy of a diamond,
until I looked at them," Blauweiss said.
The diamonds have the same chemical and physical properties of a natural mined
stone.
"That's the beauty there really is no difference," Blauweiss said.
To create them in a lab, Apollo
Diamond takes slivers of diamond crystal and exposes them to intense heat,
pressure and carbon. Another company, Gemesis,
grows these hard-to-find diamonds with intense color.
Amy Scalercio's husband surprised her with a ring designed around a stunning
lab diamond. .
"When you put it on you still feel the butterflies that you felt the first
day," she said.
Scalercio told CBS4 she's never had anyone ask if it is a naturally mined or a
real diamond.
For some people, the greatest appeal of lab diamonds may be the price tag.
Laboratory diamonds cost just a third that of a mined stone the same size.
