Montana (/mɒnˈtænə/ mon-TAN) is a landlocked state in the Mountain West subregion of the Western United States. It borders Idaho to the west, North Dakota to the east, South Dakota to the southeast, Wyoming to the south, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, the eighth-least populous state, and the third-least densely populated state. Its capital is Helena, while the most populous city is Billings. The western half of the state contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state.

Most of Montana first came under American sovereignty with the Louisiana Purchase in 1803 and was explored by the Lewis and Clark Expedition shortly thereafter. Fur trappers followed and were the main economic activity in the area until gold was discovered in 1852. The ensuing gold rush, along with the passage of the Homestead Acts in 1862, brought large numbers of American settlers to Montana. Rapid population growth and development culminated in statehood on November 8, 1889. Mining, particularly around Butte and Helena, would remain the state's main economic engine through the mid-20th century.

Montana has no official nickname but several unofficial ones, most notably "Big Sky Country", "The Treasure State", "Land of the Shining Mountains", and "The Last Best Place". Its economy is primarily based on agriculture, including ranching and cereal grain farming. Other significant economic resources include oil, gas, coal, mining, and lumber. The health care, service, defense, and government sectors are also significant to the state's economy. Montana's fastest-growing sector is tourism, with 12.6 million tourists (as of 2019) visiting the state each year. (Full article...)

A 0.65-carat (0.130 g) cornflower blue Yogo sapphire

Yogo sapphires are blue sapphires, a colored variety of corundum, found in Montana, primarily in Yogo Gulch (part of the Little Belt Mountains) in Judith Basin County, Montana. Yogo sapphires are typically cornflower blue, a result of trace amounts of iron and titanium. They have high uniform clarity and maintain their brilliance under artificial light. Because Yogo sapphires occur within a vertically dipping resistive igneous dike, mining efforts have been sporadic and rarely profitable. It is estimated that at least 28 million carats (5.6 t or 5.5 long tons or 6.2 short tons) of Yogo sapphires are still in the ground. Jewelry containing Yogo sapphires was given to First Ladies Florence Harding and Bess Truman; in addition, many gems were sold in Europe, though promoters' claims that Yogo sapphires are in the crown jewels of England or the engagement ring of Princess Diana are dubious. Today, several Yogo sapphires are part of the Smithsonian Institution's gem collection.

Yogo sapphires were not initially recognized or valued. Gold was discovered at Yogo Creek in 1866, and though "blue pebbles" were noticed alongside gold in the stream alluvium by 1878, it was not until 1894 that the "blue pebbles" were recognized as sapphires. Sapphire mining began in 1895 after a local rancher named Jake Hoover sent a cigar box of gems he had collected to an assay office, which in turn sent them to Tiffany's in New York, where an appraiser pronounced them "the finest precious gemstones ever found in the United States". Hoover then purchased the original mother lode from a sheepherder, later selling it to other investors. This became the highly profitable "English Mine", which flourished from 1899 until the 1920s. A second operation, the "American Mine", was owned by a series of investors in the western section of the Yogo dike, but was less profitable and bought out by the syndicate that owned the English Mine. In 1984, a third set of claims, known as the Vortex mine, opened. (Full article...)
