The cave is never referred to by a proper name in-game, known only as ??? in the menu in Final Fantasy VII. The location is referred to as "Lucrecia's Cave" in the BradyGames guide for Final Fantasy VII, and referred to by a similar name in the Ultimania guides for both Final Fantasy VII and Dirge of Cerberus -Final Fantasy VII-. The location is also commonly known as "Crystal Cave" by fans.
