In an age where you can get almost anything from the Internet, it's probably no surprise that you can also buy a diamond-making machine for $200.000 on the Chinese e-commerce website Alibaba. If you don't know what's going on in the diamond industry, it turns out that the availability of these machines reflects an ongoing trend toward opening up diamond production — a process that began decades ago and continues to evolve. […]
Today, there are two main methods for creating lab-grown diamonds: the HPHT process and chemical vapor deposition (CVD). Both types of machines are now available on Alibaba, with prices starting at around $200.000.
Although the idea of buying a diamond making machine on Alibaba may be interesting, it is important to note that the operation of a machine is not that simple. You won't hook her up and start picking up the diamonds she throws at you.
According to Lakha's article, these machines require significant expertise and additional resources to operate effectively. For an HPHT press, you will need a reliable source of high-quality graphite, metal catalysts such as iron or cobalt, and precise temperature and pressure control systems. CVD machines require a steady supply of methane and hydrogen gases, as well as the ability to produce and control microwaves or hot filaments.
Both methods need diamond seed crystals to start the growing process.
In addition, you will need specialized knowledge to manage growth parameters, safely handle potentially hazardous materials and high-pressure equipment, and process the resulting rough diamonds into usable gemstones or industrial components.
The machines also use significant amounts of energy and require regular maintenance.
These factors may make the process subject to certain regulations. In short, although these machines are more affordable than ever, setting up a diamond manufacturing business requires significant investment in equipment, materials, know-how and safety measures.
