Combining gold and silver may not seem like an obvious way to make diamonds. But when conditions are just right, the method works spontaneously.

Researchers have demonstrated that macroscopic crystals with diamond-like shapes and crystal lattice structures can be grown by means of a new procedure that brings together oppositely charged building blocks through electrostatic attractions. The method has been used to build three-dimensional structures from millions of gold and silver nanoparticles that were modified . . .
