In a surprising turn of events, the diamond-making process has become more accessible than ever, with machines now available for purchase on Alibaba, a major Chinese eCommerce platform. For a price starting around $200,000, anyone with the capital can potentially set up their own diamond production facility, signaling a significant shift in the industry.
This development is part of a broader trend towards democratizing diamond production, a process that has been evolving for decades. The origins of lab-grown diamonds can be traced back to the 1950s when chemist Howard Tracy Hall at General Electric first succeeded in synthesizing diamonds using a high-pressure, high-temperature (HPHT) technique. This method mimicked the natural conditions under which diamonds form.
Today, diamond production technology has progressed to include two main methods: HPHT and chemical vapor deposition (CVD). Both types of machines are now available for purchase online, with CVD machines commanding higher prices, up to $450,000.
Despite the allure of purchasing a diamond-making machine online, operating these devices is far from straightforward. According to Javid Lakha, a Harvard graduate student who recently detailed the lab-grown diamond industry, these machines require specialized knowledge and resources.
An HPHT press needs a consistent supply of high-quality graphite, metal catalysts like iron or cobalt, and precise control systems for temperature and pressure. CVD machines demand a continuous supply of methane and hydrogen gases and the capability to generate and control microwaves or hot filaments. Both methods also require diamond seed crystals to initiate the growth process.
Beyond the technical requirements, managing these machines involves handling potentially hazardous materials and high-pressure equipment safely. The energy consumption and regular maintenance demands add to the complexity and cost of running a diamond production operation.
While the availability of diamond-making machines on platforms like Alibaba indicates a more accessible future for diamond production, the reality of setting up a productive operation is far more complex. It requires substantial investment in equipment, materials, expertise, and safety measures. For now, while buying a diamond-making machine might be feasible, turning it into a successful venture remains a challenging endeavor.
