Commercial Mineral is proud to be a member of;
Commercial Mineral Company (CMC) was established in 1959, primarily as an industrial and rare mineral dealer with some “gemmy” grade rough and cut stones, CMC gradually evolved into gemstone sales, producing it’s own cut (faceted) stones from rough. Early customers were users of mineral for industry. (i.e. Sphalerte and calcite for the optical industry, quartz for the electrical industry, etc.)
Rare mineral sales were made to such well-known institutions as: The Smithsonian Institute, Harvard Museum, Cranbrook Institute in Michigan, and many others.
Commercial Mineral has grown into one of the largest full-service, wholesale colored stone houses in the Western United States. We also have a long history of participation in the international marketplace, with branch offices in Governador Valadares, Brazil (1965-1974), Bombay, India (1963-1975) and Dar es Salaam, Tanzania (1965-1968). Building on this network of long-term friends and customers and extensive experience, CMC has established direct overseas contacts with gem mines and cutters. Our affiliate office – AFCO Far East, Ltd. in Bangkok, Thailand – sells rough to international customers, produces cut from rough for CMC and serves as a buying/selling base when we are overseas.
The success of our family-owned business is based on our reputation for customer service, integrity, the highest standards of quality, flexibility and responsiveness in meeting customer needs.
