The Diamond Formula (Inventions: Untold Stories of the Beautiful Era collection)

Written by Alina Simone

A possible genius, a smidgen of madness, a twist of science, and an invention that very nearly changed the world—all collide in a giddy, unbelievably true mystery set in turn-of-the-century Paris.

In 1905, inventor Henri Lemoine claimed that he’d uncovered the secret to a coveted alchemy: creating diamonds in a laboratory. It intrigued a host of investors, and it soon made Lemoine an international celebrity. Then he disappeared.

The Diamond Formula is part of Inventions: Untold Stories of the Beautiful Era, a collection of incredible true stories from the belle epoque, an age of innovation, daring, bluster, and beauty when anything seemed possible. Each piece can be read, listened to, and marveled at in a single sitting.
