The accessory of the present invention comprises 1% to 9% by weight of germanium, 2% to 20% of indium in terms of weight ratio with respect to germanium, and the rest constituted by silver. It can provide an accessory realizing a metallic luster similar to the brightness of platinum and the health-enhancing and curing effect caused by the far-infrared effect at the same time.

A cloth having a semiconductor material deposited thereon is capable of producing a contact-potential difference when contacted with the skin for removing stiffness and recovering muscles from fatigue. The cloth is produced by pulverizing a contact-potential difference-generating substance such as germanium or silicon into a particle size of smaller than 200-250 .mu., adding 4-100 g of the pulverized substance to 1 kg of a non-conducting organic polymer resin liquid or printing color paste, and printing or coating the mixture onto a woven or knit fabric.
