This is a healing long necklace made with high-purity terahertz ore. Terahertz is said to vibrate one trillion times per second, and its gentle waves envelop the mind and body, helping to alleviate daily fatigue and stress. The elegant swaying of the long type and its natural shine beautifully accentuates the neckline. With its light and comfortable feel, it can be worn for a wide range of occasions, from casual to formal. This is a perfect item to enjoy both healing and fashion, and is also ideal as a gift for someone special.
