This can be a little tricky, but definitely easier than the Singularity achievement.
Involves a bit of planning and a bit of luck. Basically the best way to do this is when you make star gems (the ones that cause lightning go vertical and horizontal), dont blow them straight away... Save as many as you can as they carry over to the next level anyway.
Once you have at least 4, the tricky part is also having them on either the same vertical or horizontal row with one another. Blow any of the star gems to set off a chain reaction with the rest of them, and the achievement is yours.
Once again, a bit of luck is definitely involved... So GOOD LUCK!
