These light bases are brilliant for crystals that allow the light to penetrate them. 
 
There are 6 LED lights recessed in a solid round wooden base with an on/off switch.
 
The light amplifies the energy of the crystal and sends it out into the environment.
 
The crystal becomes a natural light source in the room and allows us to see its structure and inclusions more easily.
