For the past few months, NXT has been airing vignettes promoting The Diamond Mine, featuring several individuals doing mixed martial arts.

What the Diamond Mine is was never actually announced. Is it a new faction? Is it an extension of NXT? Is it a new tournament? Whatever it is, the speculation will be over next week as the latest promo on NXT showed that Diamond Mine will open next week.

The video which aired yesterday shows the words thrive, achieve, succeed, diamonds are made under pressure, pressure is pleasure, train, perform, become, this is the key, realize your potential, and pressure makes diamonds. All the words flash with MMA training in the background.

You can see the video below.
