Pure Copper Necklace | Can be tuned to a frequency Hand-twisted from pure raw copper, every strand is coiled by hand into a band that feels solid yet drapes softly along the neckline. Two polished copper beads at the opening are where your fingers rest each day. Pure copper lives and ages with you β bright when worn daily, deep and warm when it rests. No two pieces are ever alike. π On frequency: Each piece can be tuned to a resonant frequency (e.g. 144 Β· 177 Β· 188 Hzβ¦). Because every neck is different, first pick the length that fits you under Size. If you'd like your piece tuned to a specific frequency, write the frequency you want in the Note box at checkout β we'll set it when we craft yours. π Choose your length (measure around your neck where you want it to sit): β’ 45 cm (18") β sits high, in the hollow of the neck β’ 50 cm (20") β at the collarbone β’ 55 cm (22") β just below the collarbone β’ 60 cm (24") β drapes to the upper chest Care: keep away from perfume & chemicals; wipe with a soft cloth to keep the shine (or let it patina naturally). For those drawn to the raw, who trust the energy of real material and want a piece that carries a story of its own.
