Most other diamonds present more proof of various expansion phases, which deliver inclusions, flaws, and defect planes in the crystal lattice, all of which have an affect on their hardness. It is possible to treat typical diamonds beneath a combination of large force and significant temperature to generate diamonds which have been more durable when compared to the diamonds Employed in hardness gauges.[28]
Along with that, there’s a large worldwide demand for diamonds, due to their prevalent use in engagement rings – a “custom” which originated in a very intelligent advertising marketing campaign within the 1930s, based on the BBC.
Inside the 21st century, the technological innovation to produce perfect diamonds synthetically was designed.
