There is multiple ways to complete this achievement but I'm just going to explain the easiest/ fastest method that I used;
In the first warp room you need to go in to 'Turtle Woods' - to obtain the coloured gem you must complete this level without breaking any boxes, very simple. At the end of the level you will pick up a blue gem if you did it correctly, then leave the level on the platform in front to go back to the warp room.
Now that you have unlocked the coloured gem you must go in to the level called 'Hang Eight' - also in the first warp room. Make your way through the level (it is fine to destroy boxes now) until you reach a blue gem button on the floor, located on the right hand side, you can't miss it. Jump on the button and stay on it until it takes you to another area. Soon as you land, the achievement will pop.
Simple as that, happy 35G's.
