Saving the planet can't compete: Diamonds are the new solar game in Silicon Valley
Just a decade ago, Silicon Valley had
high hopes of becoming a vibrant manufacturing center by making solar panels. But price competition from abroad, particularly from China, quickly
dashed those dreams.
And so the founders of
Nanosolar, a large start-up that raised about half a billion dollars in its first six years, began exploring ways to build that would apply their expertise to new technologies.
A group of engineers and scientists, led by R. Martin Roscheisen, a founder of Nanosolar, announced on Wednesday that they had developed an
advanced approach to making diamonds, using technology derived in part from making silicon chips and solar cells, to be used by a new company.
The first synthetic diamonds appeared in the early 1950s, and the commercialization of diamond manufacturing has grown to the point that at least 10 companies now make either commercial or industrial diamonds.
But the new company,
Diamond Foundry, claims to have made proprietary breakthroughs that will make it possible to manufacture high-quality diamonds more quickly and cost-effectively than with existing technologies.
Its new approach makes it possible to “
culture”
diamonds at a cost that is on par with the best naturally occurring gems, according to the company’s founders. The company’s goal is to create a new distribution website
to compete with existing jewelry stores, which could reduce markups and therefore be more appealing to jewelry designers.
Diamond Foundry, based in San Carlos, Calif., has a notable list of financial backers, including the Zynga founder Mark Pincus; Evan Williams, a Twitter founder; Andreas Bechtolsheim, a founder of Sun Microsystems and a founding Google investor; and Andrew McCollum, a Facebook founder.
Another backer is the actor
Leonardo DiCaprio, who approached Diamond Foundry
because he was concerned about some ethical issues related to conventional diamond mining, including environmental issues.
Diamond Foundry will buy solar power credits to reduce its carbon footprint to zero, Mr. Roscheisen said, to help support its claim that it will offer a
“sustainable” alternative to mined diamonds.
Mr. Roscheisen was a graduate student at Stanford University in the same class as the Google founders, Sergey Brin and Larry Page. The pair invested in
Nanosolar, his
solar energy venture, which started producing thin-film solar panels in 2007.
By February 2013, hindered by low-cost Chinese competition, Nanosolar had laid off 75 percent of its work force.
Diamond Foundry is not the first company to try to use the technique, known as chemical vapor deposition, to grow diamonds by depositing layers of carbon atoms in a high-energy plasma field.
According to Mr. Roscheisen, the new process will make it possible to manufacture large quantities of Type IIa diamond, a pure white material that represents 1 to 2 percent of all natural diamonds. Other manufacturers also make IIa-quality gems, but the Diamond Foundry team says it has developed a process that will be more effective at “growing” diamond material, layer by atomic layer, more quickly.
Diamonds are one of the many forms that carbon may take. Diamond Foundry researchers spent years developing a new manufacturing technique based on a plasma source with a new “shape” that is 10 times as powerful as what has previously been used by manufacturers of synthetic diamonds, Mr. Roscheisen said.
“This means we can grow 100 percent pure diamond of white color” at a rate that compares to the speed at which it is mined, Mr. Roscheisen said.
“Experts in jewelry stores and gemologists cannot tell,” he said. “There’s nothing they can see.”
There are several ways to manufacture diamonds, including the application of high pressures and temperatures, the detonation of explosives that create diamond nanocrystals and using ultrasound to create micron-size diamond crystals, in addition to the vapor-deposition approach used widely in manufacturing semiconductors and solar cells.
Wuyi Wang, lead research scientist for the Gemological Institute of America, a nonprofit group that grades gems, said that the market for synthetic diamonds was extremely competitive and that many companies were trying to improve techniques to produce the stones.
In an effort to break the control that the traditional diamond industry has over the diamond market, Diamond Foundry has created an online marketplace where it will offer diamond jewelry by well-known jewelry designers, most of them
associated with Ethical Metalsmiths, an organization that encourages ethical and environmentally sound practices among jewelry makers.
It will also sell diamonds to industrial, scientific and wholesale markets. “We want to make it easy for Ph.D. students around the world to play around with diamonds,” he said.
On Wednesday, several analysts noted that when its website went live,
Diamond Foundry was not listing its diamonds below the price of its competitors.

Good luck with manufacturing anything in California. Plasma reactors use lots of electricity. The gases used to grow a diamond (pure carbon) must contain carbon in gaseous form. 95 to 98% of the gases used are not reacted and are swept out the exhaust. Exhausted where? Into the atmosphere, hence the need for carbon credits. Being located in the Bay Area, that is very expensive.
However, the plan is to compete with the existing sources and supply of high quality diamonds. That means price. As their volume capability expands (has to in order to break even with cost), they must lower their price to take market share away from competitors. That also means the African supply will be a victim to cost cutting, how? Labor will be paid less, of course. The whole idea is to destroy the operations in Africa where the environment is threatened by mining.
As other makers of synthetic diamonds acquire the same technology (plasma reactors are not new), manufacturing will be moved offshore where labor is cheap, electricity is cheaper, regulations and taxes are more business friendly.
Nice try though.
