A Diamond-Making Machine Will Cost You $200,000 on Alibaba

In an age erstwhile you tin get conscionable astir thing online, it's astir apt nary astonishment that you tin buy a diamond-making machine for $200,000 connected Chinese ecommerce tract Alibaba. If you, similar me, haven't been paying attraction to the diamond industry, it turns retired that the availability of these machines reflects an ongoing inclination toward democratizing diamond production—a process that began decades agone and continues to evolve.

The past of lab-grown diamonds dates backmost astatine slightest fractional a century. According to Harvard postgraduate pupil Javid Lakha, penning successful a comprehensive piece connected lab-grown diamonds published successful Works successful Progress past month, the archetypal palmy synthesis of diamonds successful a laboratory mounting occurred successful the 1950s. Lakha recounts however Howard Tracy Hall, a chemist astatine General Electric, created the archetypal lab-grown diamonds utilizing a high-pressure, high-temperature (HPHT) process that mimicked the conditions nether which diamonds signifier successful nature.

Since then, diamond-making exertion has precocious significantly. Today, determination are 2 superior methods for creating lab-grown diamonds: the HPHT process and chemic vapor deposition (CVD). Both types of machines are present listed connected Alibaba, with prices starting astatine astir $200,000, arsenic pointed out by technologist John Nagle (who goes by "Animats" connected Hacker News). A CVD instrumentality we recovered is much pricey, astatine around $450,000.

Not a Simple Operation

While the thought of purchasing a diamond-making instrumentality connected Alibaba mightiness beryllium intriguing, it's important to enactment that operating 1 isn't arsenic elemental arsenic plugging it successful and watching diamonds form. According to Lakha's article, these machines necessitate important expertise and further resources to run effectively.

For an HPHT press, you'd request a reliable root of high-quality graphite, metallic catalysts similar robust oregon cobalt, and precise somesthesia and unit power systems. CVD machines necessitate a dependable proviso of methane and hydrogen gases, arsenic good arsenic the quality to make and power microwaves oregon blistery filaments. Both methods request diamond effect crystals to commencement the maturation process.

Moreover, you'd request specialized cognition to negociate the maturation parameters, grip perchance hazardous materials and high-pressure instrumentality safely, and process the resulting earthy diamonds into usable gems oregon concern components. The machines besides usage sizeable amounts of vigor and necessitate regular maintenance. Those factors whitethorn marque the process taxable to immoderate regulations that are acold beyond the scope of this piece.

In short, portion these machines are much accessible than ever, turning 1 into a productive diamond-making cognition would inactive necessitate important concern successful equipment, materials, expertise, and information measures. But hey, a feline tin dream, right?

The Great Diamond Glut

Sometimes a Hacker News remark is worthy much than its value successful golden (or diamonds), and John Nagle, who developed Nagle's algorithm for improving the ratio of TCP/IP networks successful the 1980s, posted one successful effect to Lakha's article. It contains factoids astir diamonds, with sources, that are worthy relaying for anyone funny astir the existent authorities of diamond production.

One notable improvement comes from De Beers, the diamond corp known for its dominance successful the earthy diamond market. Through its R&D cognition Element Six, the institution is present capable of producing synthetic diamonds with flaw levels successful the parts-per-billion range. This level of purity acold exceeds what's indispensable for jewelry, entering the realm of high-tech applications. Element Six has adjacent managed to make diamond windows for lasers up to 10 centimeters across, showcasing the imaginable for large, highly axenic synthetic diamonds.

On the earthy diamond front, there's been a astonishing breakthrough. Nagle points retired that the manufacture has developed an concern x-ray strategy to analyse rocks earlier crushing, helping to sphere ample diamonds that mightiness different beryllium breached during extraction. This exertion has led to immoderate awesome finds, including a 2,492-carat diamond discovered past month. The sorter for this occupation comes from TOMRA, a institution known for high-volume sorting systems utilized successful recycling and nutrient processing.
