Girls like them because they’re twinkly and expensive. Guys like them as a conceptually easy gift - read the box, no creativity required. But that diamonds cost what they cost, often in the form of a two-months salary “expression of love and commitment” (good job advertising…), leaves an understandable bad taste in the male mouth. Here are some cooler diamond uses to salvage their image.
Quantum Cryptography
Diamond-based optical fiber technology has revolutionized security in data transfer. Unlike other gems, diamonds, when grown at the tips of optical fibers, have a single flaw that emits single photons at a time, so you know for sure if information is being lifted. With this technology, if one proton’s missing, you notice. Source
Chemotherapy
Nanodiamonds can be used in cancer treatment by attaching them to cancer cells in a fluorescent state, serving to clearly illuminate areas to send medicine. How do you create fluorescent nanodiamonds? By detonating TNT and RDX, and taking diamonds on the nanometer scale from the soot, then blasting them with high energy helium ions. Being carbon-based, the human body doesn’t really have compatibility issues. Source
Precision Cutting
With their near-indestructibility, diamonds are and have been a great choice for cutting/engraving/etching. Used in everything from mining to precision surgery, they’re the only choice for long-term, exact use. Even if they are still diamonds and do still cost some good money, their reliability in lucrative applications keeps them employed. Source
Data Storage
Wants to hold a TB on a single disc? Single crystal diamond spheres are key to the next wave in data storage, as accurate tiny lenses needed to work with a readout laser operating at extremely short wavelengths. With its high refractive index and transparency, diamonds are the perfect choice. Source
Studying High Pressure Conditions
This 20th century invention uses two diamonds pressed against each other by a force-generating mechanism, creating an intense amount of pressure by the focusing of that applied force onto the small area where they meet. Observing high quality, flawless diamonds in this way allows for an in-lab study, illuminating difficult to observe large-scale pressure conditions such as pressure at the center of the Earth and on other planets. Flawless victory. Source
