This article discusses the sale of industrial machinery for manufacturing artificial diamonds. The mention of specific products and pricing is for informational purposes only and does not constitute an endorsement or verification of the commercial listings.
Diamonds are formed under high temperature and pressure deep within the Earth, but they can also be produced artificially. The Chinese online shopping platform Alibaba is selling a machine capable of manufacturing artificial diamonds for $200,000 (approximately 28.2 million yen). For orders of 10 or more units, the price per machine drops to $190,000 (approximately 27.8 million yen), representing a 5% discount.
The company offering the diamond manufacturing machine is Henan Huanghe Whirlwind, a China-based firm and the world’s largest manufacturer of diamond production equipment.
There are two primary methods for creating artificial diamonds: the High Pressure High Temperature (HPHT) method, which mimics natural diamond formation by subjecting graphite to extreme heat and pressure, and the Chemical Vapor Deposition (CVD) method, which involves depositing carbon from gases like hydrogen or methane. Henan Huanghe Whirlwind sells HPHT machines on Alibaba.
Thanks to these machines, producing diamonds for applications like lasers, with diameters up to 10 cm, has become relatively straightforward. Hacker News user Animats, who discovered the machine listing, commented:

In contrast, regarding natural diamonds, advancements in industrial X-ray systems that scan rocks prior to mining have enabled researchers to locate giant diamonds that were previously difficult to find.
Most recently, in August 2024, a 2,492-carat diamond, the second largest ever recorded, was discovered in Botswana.
