Clear quartz crystals are the most recognized type of crystal.

Placement for Good Feng Shui
You can freely place the clear quartz anywhere you feel the need to and don't be shy to experiment and move them from place to place. You might feel the need to have several points in your Creativity Bagua area, for example, and then a couple of months down the road you will sense the need to move them close to your front door. Trust your feelings and listen to your crystals.
