Similar to how pressure turns coal into diamonds, subjecting diamonds to large amounts of strain gives desirable electronic properties to the gem.

By introducing germanium to the diamond crystal lattice, scientists have succeeded in producing single photons in a narrow, high energy wavelength band.
Most of us know that diamonds are mined from the earth, but did you know that they can also be grown in the laboratory?
