Quartz is an amplifier.  That makes this a wonderful piece to place in the center of a grid.  Quartz can also be programmed.
 
These spheres have wonderful stridations which makes them a look like a planet.
 
The spheres are a little larger than a dime and will fit nicely on the little acrylic stands in the stands category.
