Clear Quartz is a Master healer and works to align and balance all the chakras. Clear quartz contains the vibrations of the entire rainbow spectrum of color frequencies. It stimulates the immune system and is the most powerful energy amplifier of the entire crystal kingdom.
Crystals with Rainbows are natural healing crystals which have prisms of light that produce rainbow colors within the crystal. Rainbows in crystals are often caused by fractures or drops of water that have seeped into the crystal during formation. They are known to symbolize happiness and optimism. And they also act as a bridge between worlds/dimensions. When crystals have a rainbow inside, it usually is a sign that the spirit of the crystal is ready to make a human connection. It is believed that finding a crystal with a rainbow within is a sign that the crystal is ready to go home with you.
