OTC International, Ltd. company, a jewelry retailer and wholesaler, makes and markets pieces in fine gold or tarnish-resistant sterling silver with cameos, semi-precious gemstones, and diamond accents. As a volume producer, OTC specializes in private-label licensed jewelry pieces and watches. The company, whose headquarters spans some 100,000 sq. ft., manages a staff of artists, designers, photographers, and advertising professionals.
