Benamite
Benamite was a rare and unstable form of crystal which was extremely difficult to synthesize.

In 2375, the crew of the  constructed a quantum slipstream drive, at the heart of which were benamite crystals. Although it was eventually discovered that constant phase variances in the quantum threshold could make the journey extremely hazardous, the crew elected to risk implementing the slipstream drive anyway, as the crystals had already started to decay, and synthesizing more could have taken years.

In 3188, Cleveland Booker described obstacles to interstellar travel to newly arrived time traveler Michael Burnham, including the widespread lack of dilithium or benamite. ()
