Rainbow, moonstone, and blue topaz 
In Ancient Rome, Moonstones were believed to be solidified rays of moonlight.
As ancient as the moon itself,  this sacred stone deeply connects to the Feminine Divine. The vivid blue sheen is associated with spiritual insight.
Blue Topaz has been used for its calming energies from ancient times. Well known for its relaxing and calming energies, soothing effects on the nerves and emotions, and universal wisdom and guidance. 
Both of these stones are deeply associated with the element of water, offering a center for the fertile imagination and the subconscious mind.
