Oh in the Ruby Room? Yeah that should be easy to get back to. Just take that first Rock Climb wall up, go past the minecart tracks, and up to the Strength rocks and move past them to the right (following the golden path), over the rock pile (Blake's), and out the east exit. In the next room go up the rock walls to the right, go up a bit and navigate east through the maze thing, climb over the next rock pile (Fern's), and out the eastern door again. Now you should be outside and can just head all the way east to the room with Florinia and the warp panel, where you can take the warp back to the center of the crystal chambers. Hopefully that helped!
