Help to find all gems on 7 lvl.

I am very,very sorry for the late reply! In level 7, there is a gem to the right of your initial spawn within a hidden block. One gem is in another hidden block between the spikes and fans (the hidden block is between two spike blocks). Another gem is by the water. A fourth gem can be found near the first sawblade. A fifth can be found by heading right (past the third raccoon monster) and dropping down and following a trail of hidden blocks until you reach a gem inside one of the blocks. The sixth gem is underneath the cannon, inside yet another, hidden block.
