you have to bend down (move your arrow down until it is orange) and when the arrow says jump, do it right then and there or else you will fall. the large pointy rocks sticking up are what causes you to have to jump
On the mine car rolling through the Diamond Mines, duck down when you get close to the roof, and jump over any rock that sticks up (there's a warning sign).
All you need to do in the Diamond Mine cart is to duck down into the cart when the ceiling gets close, then jump over the wooden barriers (it says "Jump" a little late).
In the Diamond Mine, the final stage is a cart ride through the mine. When the track gets close to the ceiling, duck down into the cart. When you come to a board sticking out over the tracks, jump it. (You may have to jump before you see the sign that says "jump".) After three sets of ducking and jumping, you reach the end of the cart track. Use the magnifier at the bottom right of the screen to examine the diamonds, and find the one that has the triangular mark identifying the White Jewel of the Nabooti. (see related question)
you must finish the cart ride or go backwards to the end of the cave and press the green button
