Peridot is a well-known and ancient gemstone, with jewelry pieces dating all the way back to the Pharaohs in Egypt. The gem variety of the mineral Olivine, it makes a lovely light green to olive-green gemstone. It is a common mineral often found in lavas and in deep mantle rock, which lavas carry to the surface. Peridot is usually found as small grains, and tends to exist in a heavily weathered state, the green sand beaches of Hawaii are composed of Peridot.
Judy Hall in The Crystal Bible says this about Peridot:
In ancient times, Peridot was believed to keep evil away evil spirits. It is still a protective stone for the aura. This stone is a powerful cleanser. Releasing and neutralizing toxins on all levels, it purifies the subtle and physical bodies, and the mind. It opens, cleanses and activates the heart and solar plexus chakras and releases “old baggage”.
The "A#" tuning of this bowl works with the Third Eye Chakra and stimulates the Pineal Gland. The Pineal Gland, tucked deep in the middle of the brain, regulates your daily and seasonal circadian rhythms, the sleep-wake patterns that determine your hormone levels, stress levels, and physical performance. It is thought by some to be the connecting link between the physical and spiritual worlds. The A# combined with Peridot in this bowl strengthens and protects your intuitive voice and would be a great choice for artists, writers and all those in creative fields.
