77 Diamonds has acquired the first known glow-in-the-dark diamond: the 2.5 carat Green Star.

'An unusually high dose of subterrestrial radiation during formation, could, in theory, have produced this effect,' explains Dr. M. Videnskabmand of the University of Copenhagen's Department of Geophysics.

'Radiation is known to affect the colour of diamonds, but this would be the first recorded example of it imparting luminescence as well. It's a frankly astonishing discovery.'

While setting it in an engagement ring might not be a possibility, we're inspired. Glo-sticks, anyone?
