These awesome LED Lamp Stands that can be used for ANY of your crystals that have transparent properties, such as these fluorite spheres in the photos (spheres not included, see seperate listing)
 
They are USB operated and have an on/off switch also.   I bought for me, loved them so much that thought better offer here too! 
 
Photo of stall is satin spar lamp shade with this underneath. 
 
En Joy!
