Diamond Light Source
Diamond Light Source is the United Kingdom's national synchrotron science facility at Harwell near Didcot, Oxfordshire, using X-rays from accelerated electrons to study matter at atomic scale.
Diamond magnetometry
Diamond magnetometry measures magnetic fields using the electronic spin of nitrogen-vacancy color centers in diamond, enabling nanoscale-resolution magnetic imaging at room temperature, proposed and demonstrated in 2008.
Diamond maser
A diamond maser is a microwave oscillator or amplifier using nitrogen-vacancy defect centers in diamond, first shown to operate continuously at room temperature and ambient pressure in 2018.
Diamond mining in Angola
Diamond mining in Angola is the extraction of diamonds, begun in 1912 and now led by the state company ENDIAMA, concentrated in the northeastern Lunda provinces.
Diamond Multimedia
Diamond Multimedia, also known as Diamond Computer Systems, was a California maker of PC peripherals, including Stealth graphics cards, Supra modems, and the Rio MP3 player, acquired by S3 in 1999.
Diamond nanophotonic cavities for NV centers
Diamond nanophotonic cavities for NV centers are photonic-crystal and microcavity structures in diamond that concentrate optical fields around a nitrogen-vacancy center, boosting its spin-photon coupling toward scalable solid-state quantum networks.
Diamond nanophotonic quantum network
A diamond nanophotonic quantum network is a quantum network whose nodes are color-center qubits, such as NV and SiV centers, embedded in nanoscale diamond optical structures connected by fiber.
Diamond norm
The diamond norm, also called the completely bounded trace norm, is a norm on linear maps introduced by Alexei Kitaev to measure the worst-case distinguishability of two quantum channels.
Diamond Oil Pipeline (Memphis–Byhalia)
The Diamond Oil Pipeline is a 440-mile crude oil pipeline from Cushing, Oklahoma, to Valero's Memphis refinery, owned by Plains All American and Valero with a capacity of 200,000 barrels per day.
Diamond Peak
Diamond Peak names several US mountains: a 10,619-ft Eureka County, Nevada high point in the Diamond Mountains, the Diamond Peak ski resort at Incline Village, Lake Tahoe, and peaks in Lassen park, Oregon, and Idaho.
Diamond photonics
Diamond photonics builds optical devices, from waveguides to integrated circuits, out of single-crystal diamond, whose color centers serve as single-photon sources, spin qubits, and quantum memories.
Diamond Platnumz
Diamond Platnumz (Naseeb Abdul Juma Issack, born 1989) is a Tanzanian bongo flava superstar from Tandale, Dar es Salaam, founder of WCB Wasafi, first sub-Saharan artist to one billion YouTube views, and a 2015 MTV EMA winner.

Diamond Princess is a Grand-class cruise ship operated by Princess Cruises, built by Mitsubishi Heavy Industries in Nagasaki, Japan, in 2004 and known for the 2020 COVID-19 outbreak during quarantine at Yokohama.
Diamond rain
Diamond rain is the hypothesized precipitation of solid diamond crystals through the mantles of ice giants like Uranus and Neptune, an idea proposed by Marvin Ross in 1981 and tested in laboratory experiments since.
Diamond Rio
Diamond Rio is an American country band formed in Nashville in 1989 from the Tennessee River Boys, signed to Arista Nashville in 1990. Its 1991 debut single "Meet in the Middle" was the first by a country group to hit No. 1; six Vocal Group of the Year awards and a 2011 Grammy for The Reason.
