Electrokinesis would actually be one of the stronger type of manipulations, given gems natural affinity for it. Indy in general has both forcefields and electrokinesis, which allows for a general concept for natural enhancement in the power of the electromagnetic force. This would likely work for alignment and density increase over a distance, likely through quantum entanglement with a predefined radius.

Overall, long story short, it is like how they make their forms, except instead of light, it is with the electromagnetic messenger particles. This focuses them, and allows for electrokinesis and forcefields.
