topaz (mineral) (mineral, inorganic material, ... Materials (hierarchy name)) |
|
Note: An aluminum silicate containing fluorine that is formed by fluorine-bearing vapours given off during the last stages of the crystallization of igneous rocks. The topaz that is valued as a gemstone occurs in prismatic crystals that are transparent and lustrous, of white (colorless), yellow, brown, pale blue, pink, red, or pale green color, found in Brazil, Mexico, Saxony, Scotland, Japan, the Ural Mountains, and elsewhere. Colorless topaz may be mistaken for diamond when brilliant cut. Colored topaz may be unstable and bleached by sunlight. It is believed that the topaz identified by modern mineralogists was unknown to ancient Greece and Rome and the writers of the Old Testament; the stone called "topazos" by the ancients was probably the minerals chrysolite, peridot, or yellow sapphire.

Additional Notes: |

| Chinese (traditional) ..... 含氟的矽酸鋁，由火成岩結晶化過程的最後階段散發出的含氟蒸氣所形成。可作為珍貴寶石的黃玉呈現稜狀結晶，透明又具有光澤，呈現的顏色有白色 （無色）、黃色、棕色、淡藍色、粉紅色、紅色或淡綠色，分佈於巴西、墨西哥、薩克森、蘇格蘭、日本、烏拉山脈及其他地方。無色的黃玉在切割精良下，可能被誤認為是鑽石。有色的黃玉可能較不穩定或因日照而褪色。一般認為，現代礦物學家所鑑定出來的黃玉，古希臘、羅馬人和舊約聖經的作者並不知曉，而古人稱為「黃晶」（topazos）的石頭，有可能是橄欖石、貴橄欖石或黃晶的礦物。 |
| Dutch ..... Een aluminiumsilicaat dat fluor bevat dat is gevormd door fluorhoudende dampen die zijn afgegeven tijdens de laatste fasen van het kristalliseren van stollingsgesteente. De topaas, die als edelsteen zeer geliefd is, komt voor in prismatische kristallen die transparant en glanzend zijn en een witte (kleurloze), gele, bruine, lichtblauwe, roze, rode of lichtgroene kleur hebben. Onder meer aangetroffen in Brazilië, Mexico, Saksen, Schotland, Japan en de Oeral. Kleurloos topaas kan worden aangezien voor diamant wanneer het is geslepen. Gekleurd topaas kan onstabiel zijn en verbleken door zonlicht. Men meent dat het mineraal dat moderne mineralogen met 'topaas' aanduiden, niet bekend was in het oude Griekenland en Rome en bij de schrijvers van het Oude Testament; de steen die door deze oude beschavingen 'topazos' werd genoemd, was waarschijnlijk het mineraal chrysoliet, ofwel peridot of gele saffier. |
| Spanish ..... Mineral ortorrómbico; se presenta como constituyente menor en rocas ígneas silíceas. Se utiliza como gema.
