Measures approximately 13" in diameter. Features:
Iridescent glass: white/rainbow flashing moon
Iridescent glass: Light blue/rainbow outer layer

My favorite detail about this piece is the glass surrounding the small grey star under the moon. The natural variation in color give it the motion of a shooting star!
