What: Perfect single-crystal diamonds of more than two carats
(the average engagement ring is less than a carat) churned out in a day. Scientists create the gemstones using a process called chemical vapor deposition (CVD), which grows diamond crystals one carbon atom at a time.
Why: The jewelry industry has shown great interest in ersatz versions of the 45-carat Hope diamond, but other uses could prove more lucrative. Using CVD, scientists will be able to cheaply mass-produce diamond semiconductors that are hundreds of times as powerful as their silicon counterparts.
Who: Russell Hemley of the Geophysical Laboratory of the Carnegie Institution of Washington and researchers at Apollo Diamond, Inc., in Boston, have produced the largest and some of the most flawless diamonds so far. And Europe´s Carbon Power Electronics consortium, led by Dutch diamond maker Element Six, has created a synthetic diamond diode, the first step toward working diamond semiconductors.
When: During the past year, scientists have mastered the ability to grow 10-carat single crystals with a color and clarity that surpass mined diamonds. Within a decade, they´ll also be cheaper. Expect to see the first diamond semiconductors hit the market in 2011.
How To Grow a Diamond
- Launch the slideshow to see how flawless man-made diamonds are grown.
Is there not two common ways to produce man made diamonds? High pressure and a low pressure creation of man made diamonds, where the CVD is considered the low pressure. Is there a cap on how large the high pressure diamonds can be produced and obviously they are not very suitable for electronics but for jewelry are there any differences?
The look of diamonds always impresses. It's the symbol of luxury. Every woman wearing <a href="http://www.diamondrocks.co.uk/Diamond+Engagement+Rings.htm" title="diamond engagement rings">diamond engagement rings</a> feels charming and confident.
In the pic, that looks like a graphite structure, not a diamond cubic.
