Although it was discovered in Japan, it initially gained popularity among New Age practitioners and healers in the United States, and later became popular in Japan as well. In America, it is called "Sugilite" and is loved by many as a power stone that opens the "third eye" (a spiritual gate believed to exist around the brow) and enhances spirituality, promoting the evolution of the soul and consciousness. Purple is considered a noble and sacred color that enhances spirituality, and Sugilite strongly emits that vibration. The healing and purifying power of this stone is so strong that it is said that "Sugilite does not need purification." It was hailed as the best healing stone discovered in the 20th century, and there were even rumors that it "activates and regenerates cells." While it may not have that much power (lol), Sugilite is said to purify the mind and body, remove negative energy, and energize and activate.
