A new diamond sales website, Diamond Foundry, was recently launched. On this site, a 1 carat diamond is only about $3,000, and many designer diamond rings with diamonds are only a few thousand dollars. It’s not that the eyes are flashed with the wrong price. These diamond jewelry labeled “100% pure†are made by hand. This new online site may not be famous now, but the investors behind it can list a list of deafening names, Leonardo DiCaprio is one of them. 
About a decade ago, Silicon Valley was full of dreams everywhere, to become the world's solar panel manufacturing center. Later, ultra-low-cost solar panels exported by China quickly shattered this fantasy.
Nanosolar is one of these dream-breaking Silicon Valley solar manufacturers. The startup financed $500 million in the first six years of its creation, and all of them have been squandered. Nanosolar founder R. Martin Roscheisen graduated from Stanford University and is a classmate with Google founders Sergey Brin and Larry Page. The latter two also invested in his Nanosolar. Nanosolar has been manufacturing thin film solar panels since 2007. In February 2013, 75% of employees were abolished due to competition from Chinese solar panels. However, Nanosolar is not completely unfounded. They found that the past business model failed, but the original accumulated technology can be used to develop a brand new product - diamond.
Rothsson announced on Thursday that they invented a new way to make diamonds based on their previous experience in making solar cells. The earliest synthetic diamonds appeared in the early 1950s, and artificial diamond manufacturing has been commercialized so far, with at least 10 companies producing artificial diamonds for commercial or industrial use.
Roseson established a brand new company called "Diamond Foundry", claiming to make high-quality diamonds at a lower cost and faster process through breakthroughs in major technology patents. Diamond Foundry called the new technology to incubate diamonds that are of a quality comparable to natural gemstones and compete with current jewelers at a lower price.
Big-name investors have been unpacking
Diamond Foundry is headquartered in San Carlos, California. The new company has a list of shiny investors, including Zynga's founder Mark Pincus, Twitter founder Evan Williams, Google's early investor Andrea Andreas Bechtolsheim, and Facebook founder Andrew McCollum.
Another famous investor is the movie star Leonardo DiCaprio, who is said to have invested in Diamond Foundry because DiCaprio has always been concerned about some of the ethical issues in the traditional diamond mining industry. DiCaprio has starred in the movie "Blood Diamond", and the film explains the bloody inside of diamond mining.
Diamond Foundry also hopes to differentiate itself from the traditional diamond industry by purchasing carbon credits to achieve a zero carbon footprint throughout the manufacturing process.
According to Roscheisen, the company's new technology will be able to mass-produce Class IIa diamonds, and the IIa level is called “diamonds in diamondsâ€. In natural diamonds, this level of diamonds only accounts for 1% to 2%. The method used by Diamond Foundry is chemical vapor deposition. This method is not new, and many manufacturers are using it to make IIa grade diamonds.
But Diamond Foundry claims that the researchers have improved the technology for several years. By modifying the shape of the plasma field, the research team can improve the reaction efficiency of the diamond structure and greatly accelerate the diamond production process. The specific process begins with a very thin piece of natural diamond, using a natural diamond as a substrate, and then gradually adding a layer of carbon atoms to slowly expand the original diamond matrix. Rothsson said there is a way to easily infer whether the IIa diamond is artificial or natural. Because IIa grade diamonds are very rare in nature, so long as you see a large number of such diamonds appear, it is definitely fake. But looking at one is hard to tell.
"Jewelers and jewelers can't find that there are no features that can tell the difference," Rothsson said. Wuyi Wang, chief scientist of the American Jewelry Association, said that the artificial diamond market is currently highly competitive and many companies are trying to improve technology to produce diamonds. Wuyi Wang also said that he has not checked the diamonds of Diamond Foundry, but he believes his laboratory can distinguish between natural and artificial Type IIa diamonds.
However, distinguishing between artificial diamonds and natural diamonds requires special equipment and techniques, and it is difficult for ordinary consumers to determine the two. To break the traditional diamond dealer's control of the market, Diamond Foundry also launched an online website to work with some famous jewelry designers to design a variety of affordable diamond jewelry.
