Silver-plated alloy (also shown in a rose-gold-tone finish) with a woven mesh inner band. Wipe with a soft dry cloth after wearing, keep away from perfume, lotion and water, which dull plating over time, and store the pair in a pouch so the interlaced bands don't scratch against other pieces. Because the mesh texture has more surface detail than a smooth band, residue from lotion or perfume tends to settle into it more visibly, so it's worth a slightly more frequent wipe-down than a plain hoop.
