Diamond Materials
How diamond is grown in labs and how it compares with mined stone.
Start here · Essential guide
A plain-language look at how carbon becomes diamond in a lab, from high-pressure presses that mimic the deep Earth to gas-phase growth at low pressure.
How synthetic diamond grit is separated by size, shape and strength, and why those three sorting steps decide where each grade ends up in industry.
A side-by-side comparison of high-pressure and vapor-deposition diamond growth, including how each route works, what it tends to produce and where it is used.
A survey of how synthetic diamond production has developed since the 1950s, and which improvements in size, cost and quality have mattered most.
Mined and lab-made diamond compared on supply, consistency and properties, with a sober look at what each is best suited to in industry and beyond.
A short history of how lab-grown diamond went from a scientific curiosity in the 1950s to a routine industrial input, and why it is not exactly a new era.
Why most diamond used in industry is synthetic, starting with abrasive grit and powders, and how that base expanded to compacts, coatings and heat management.
A closer look at the conditions that shape a growing diamond crystal, including temperature, pressure, gas mix and purity, and how each affects quality.
