I am stuck in the lava room of Sky Keep. I managed to unlock three areas with gems by dropping bombs into baskets. First was one near the entrance, second was behind some foliage, and third was down a sand slope. I found that if I shoot each of the three gems with a bow and arrow, or use the beetle, they turn gray.
However, nothing happens after I shoot all three. They turn pink again. I thought it might be on a timer, so I tried to shoot them all really quickly, but that didn't work. I thought there might be a forth gen beyond a barred door, but if there is, I don't know how to open it.
What do I do with these three gems?

A sign next to the exit tells you what you need to do.
After uncovering all three switches, simply strike the switches in order based on their elevation within the room, from lowest to highest, in order to progress.
To be exact, the correct order is:
The one at the bottom of the sand slope
The one near to the entrance
The one behind the thin trees
