The simplicity of the small 14mm Hallmarked 925 Sterling Silver Harmony Ball pendant makes this delightful silver jewelry to a discreet, shiny adornment that surprises with its soft sound, when it dangles on a chain, embellishing the neckline with its brilliant shine. The brass ball inside produces this relaxing, meditative sound that harmonizes a woman's stress level and has a relaxing influence. Also known as "chiming spheres" or "angel callers" in Spanish: “llamadores de angeles”.
