North America Canada The country's other major gem exports are ammonite and labradorite, which was originally discovered in the province of Labrador. Canada remains a major source of labradorite, especially in fine qualities, although precise figures aren't available. Ammonite is retrieved from the Milk River in Alberta, and remains relatively rare. Other gem deposits have been discovered throughout the country. Commercial interests are mining sapphire and iolite in British Columbia, emerald and blue beryl in the Yukon, and sapphire on Baffin Island; currently all are in the exploration stage. Fee-dig operations are mining opal in British Columbia and amethyst in Ontario, and various other sites are open to collectors, but none of them produce gems in commercial quantities. Mexico The Chiapas state of Mexico is known for its amber, most of which comes from an area in the Chiapas highlands near the town of Simojovel. The material is much clearer than that from other deposits, and it is highly prized for its transparency and impressive color, including reds. Production remains limited, however, and is estimated at about 200 kilograms per year. Production of good-quality amethyst in Guerrero state has drastically dropped since flooding at the mines about five years ago. Veracruz also continues to produce amethyst, but lower demand, the flow of material has slowed. The state also produces demantoid garnet. United States Commercial mining of gemstones is almost exclusively conducted by family-operated mines or by small, privately-held companies. Other producers are individual collectors or miners, gem and mineral clubs, fee-for-dig operations, and other part time or semi-professional operations. The majority of the value of U.S. gemstones comes from just seven states: Oregon, Arizona, California, Montana, Nevada, Idaho, and Arkansas, in decreasing order of value produced. Arizona Once the world's largest producer of peridot, mining in Arizona's San Carlos Apache reservation has been impacted by material from China. Chinese dealers are selling cut peridot for less than the asking price of Arizona peridot rough, pricing it out of the market. California Montana Nevada and Idaho Oregon Oregon sunstone operations appear to still be operating, but production may be affected in the future by the need to meet federal requirements for high-cost reclamation bonds. Utah One of Utah's most famous gemstone mines, the Red Beryl Mine, reportedly has or is undergoing an ownership change; it is also rumored that the resources in the lower portion of the deposit are nearly exhausted. |
