topaz 黃寶石，黃玉

來自拉丁語 topazus,來自希臘語 topazos,黃玉，黃寶石，據說是紅海或阿拉伯海的某島名，因產自該島而得名，而該詞本身來自希臘語 topazein,搜尋，尋找，因該島不易找到而得名。另一名說法是來自梵語 tapas,火，火紅色，在中世紀時期用來指各種黃寶石。

topaz (n.): colored crystalline gem, late 13c., from Old French topace (11c.), from Latin topazus (source also of Spanish topacio, Italian topazio), from Greek topazos, topazion, of obscure origin. Pliny says it was named for a remote island in the Red or Arabian Sea, where it was mined, the island so named for being hard to find (from Greek topazein "to divine, to try to locate"); but this might be folk etymology, and instead the word might be from the root of Sanskrit tapas "heat, fire." In the Middle Ages used for almost any yellow stone. To the Greeks and Romans, possibly yellow olivine or yellow sapphire. In modern science, fluo-silicate of aluminum. As a color name from 1908.
