Yogo sapphire

Yogosafirer är blå ädelstenar av mineralet korund och är en av de mest uppskattade ädelstenarna. Yogosafirer är en varietet av safirer, som finns endast i Yogo Gulch, i Little Belt Mountains i Judith Basin County, Montana, USA, på mark som en gång beboddes av svartfotsindianer. Den mest värdefulla färgen hos safiren är den blåklintsblå färgen. Yogosafirer är vanligtvis kornblå, ett resultat av spårmängder av järn och titan. De har hög enhetlig klarhet och behåller sin briljans under artificiellt ljus. rdf:langString

rdf:langString Yogo sapphires (kurz Yogos) sind Saphire aus der Schlucht Yogo Gulch in Montana. Die Schlucht liegt in den in den Rocky Mountains, im Judith Basin County. Das Land gehörte früher den Piegan (Blackfeet). Saphire sind Varietäten des Minerals Korund. Die meisten Yogos haben die für Saphire erwünschte tiefblaue Farbe, die sie ihrer geologischen Entstehung verdanken. Nach Einschätzung vieler Gemmologen, die diese Farbe assoziativ als „Kornblumenblau“ („cornflower blue“) bezeichnen, gehören sie zu den hochwertigsten Saphiren der Welt. Sie zeichnen sich durch gleichmäßige Transparenz aus und glänzen auch bei künstlichem Licht. Da die Saphire im Yogo Gulch in einem vertikal geneigten magmatischen Dyke vorkommen, war ihr Abbau sporadisch und selten profitabel. Es wird geschätzt, dass noch mindestens 28 Millionen Karat (5,6 t) Yogos im Boden zu finden sind. Schmuckstücke, die Yogos enthalten, wurden den First Ladies Florence Harding und Bess Truman geschenkt. Etliche Yogo sapphires sind Teil der Sammlungen der Smithsonian Institution.

rdf:langString 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. The term "Yogo sapphire" is the preferred wording for gems found in the Yogo Gulch, whereas "Montana sapphire" generally refers to gems found in other Montana locations. More gem-quality sapphires are produced in Montana than anywhere else in North America. Sapphires were first discovered in Montana in 1865, in alluvium along the Missouri River. Finds in other locations in the western half of the state occurred in 1889, 1892, and 1894. The Rock Creek location, near Phillipsburg, is the most productive site in Montana, and its gems inspired the name of the nearby Sapphire Mountains. In 1969, the sapphire was co-designated along with the agate as Montana's state gemstones. In the early 1980s, Intergem Limited, which controlled most of the Yogo sapphire mining at the time, rocked the gem world by marketing Yogo sapphires as the world's only guaranteed "untreated" sapphire, exposing a practice of the time wherein 95 percent of all the world's sapphires were heat-treated to enhance their natural color. Although Intergem went out of business, the gems it mined appeared on the market through the 1990s because the company had paid its salesmen in sapphires during its financial demise. Citibank had obtained a large stock of Yogo sapphires as a result of Intergem's collapse, and after keeping them in a vault for nearly a decade, sold its collection in 1994 to a Montana jeweler. Mining activity today is largely confined to hobby miners in the area; the major mines are currently inactive.
