It's common to behave diamonds have value, even when they are made in a lab at a fractional cost?

In a study published in Nature, researchers from China synthesized bulk hexagonal diamond, ranging from 100-µm-sized to mm-sized, with a highly ordered structure by compressing and heating high-quality graphite single crystals under pressure conditions as uniform as possible.
The designed material, which was recoverable under ambient conditions, unveiled the previously elusive structural world of HD, opening new avenues for exploring its potential as a technologically superior material.
Apart from being a dazzling element in jewelry, diamonds, due to their unmatched chemical and physical properties, are sought after in a wide range of applications, including biosensors, quantum computing, and industrial processes as superabrasives and drilling bits.
