Our "granules" in jewelry are tiny, carefully enclosed grains that enhance the unique appearance and symbolic meaning of each piece. In practice, they are usually glass or plastic beads, or other inert materials, separated from the skin by a tight enclosure, preventing direct contact with the contents. Scientifically speaking, such enclosed particles do not cause any biological or systemic effects in the body; claims of physical "resonance" or direct healing effects are not supported by medical evidence. However, many wearers do experience a stronger emotional support, peace, or sense of protection—effects that stem from symbolism and personal conviction, and which can be very valuable in everyday life.
