What are five uses for diamonds today?

Answer 1

1. Jewellery & Gemstones

Diamonds are most famously prized as gemstones in engagement rings, earrings, and fine jewellery due to their brilliance, durability, and symbolic association with eternal love. They remain the traditional choice for bridal jewellery worldwide.

2. Cutting, Drilling & Abrasives

Due to their unmatched hardness (rated 10 on the Mohs scale), diamonds are essential in industrial tools—embedded in drill bits, saw blades, grinding wheels, and polishing pastes to cut or shape extremely hard materials like concrete, glass, ceramics, and gemstones. Nearly 80% of all diamonds mined are used this way.

3. Precision & Scientific Instruments

Diamonds are used in devices like diamond anvil cells for high-pressure research, as well as in high-performance bearings, indenters for hardness testing, and precision tips in microscopy and engineering equipment. Their strength and stability make them invaluable in scientific experimentation.

4. Electronics & Thermal Management

Diamond’s high thermal conductivity and electrical insulation properties make synthetic diamonds ideal as heat sinks or heat spreaders in advanced electronics, lasers, and semiconductor devices—helping protect sensitive components from overheating.

Future & Medical Uses

Emerging applications include nanodiamonds in medical imaging and cancer research, potential use in bionic implants, and custom 3D-printed diamond implants for orthopaedic use. Researchers are also exploring diamonds for quantum sensing and high‑end optical components.

In summary, diamonds are far more than luxury gems—they’re essential industrial, scientific, electronic, and even medical materials, prized for their unmatched hardness, thermal properties, and durability.

Answer 2

Diamonds are most common organized as industrial diamonds -- about 80% of all diamonds mined, and the remainder as gem-quality diamonds.

Gem-quality diamonds are used primarily as economic currency with the addition of sentimental value, depending on who gives and who receives the diamonds.

Industrial diamonds are used to enhance the precision of cutting tools, regardless of the size. There are too many additional uses for industiral diamonds to list here.
