It is a fluorine aluminium silicate and comes in yellow, yellow-brown, honey-yellow, flax, brown, green, blue, light blue, red and pink ... and sometimes it has no colour at all. The topaz.

The topaz has been known for at least 2000 years and is one of the gemstones which form the foundations of the twelve gates to the Holy City of the New Jerusalem. These so-called apocalyptic stones are intended to serve in protection against enemies and as a symbol of beauty and splendour. It cannot be proved conclusively whether the name of the topaz comes from the Sanskrit or the Greek, though the Greek name 'topazos' means 'green gemstone'. The Romans dedicated the topaz to Jupiter.

The colour in which the topaz is most commonly found is yellow, and that is the colour in which it occurs in one of the major German gemstone rocks, the Schneckenstein (a topaz-bearing rock said to resemble a snail) in Saxony. In the 18th century, it was mined there during a period of over 60 years. However, most of the crystals were hardly a centimetre in diameter. You had to go to Siberia or Brazil to find crystals as large as your fist. Having said that, anyone who is interested can convince himself of the beauty of cut specimens in the topaz set in Dresden's Grünes Gew?lbe (Green Vault). The enormous and magnificent topaz from the Portuguese crown, the Braganza, was for a long time thought to be a diamond. It weighs 1680 ct..

In mysticism, the topaz is attributed with a cooling, styptic and appetising effect. It is said to dispel sadness, anger and nocturnal fears, to warn its wearer of poisons and protect him or her from sudden death. It is reputed to make men handsome and intelligent and sterile women fertile and happy. However, it is probably better not to rely too much on its magical powers, since it was also claimed that you could immerse your hand in boiling water after a topaz had been thrown into it and retract it again unharmed! It is the stone of the month November.

In the Empire style, the topaz was still widespread, but then the more reasonably priced citrine took over from it and even usurped its name - gold topaz. Since then, the topaz has been a rather exotic figure in the jewellery trade, and has been given the additional predicate 'pure' to make it clear that the topaz, not the quartz topaz, is meant. And it is still waiting for its well deserved come back to this day.

 

Topaz名字由来

托帕石的英文名稱為Topaz,名稱來源有兩種說法:一種說法是由希臘文“Topazios”演變而來的,原指紅海中一個稱“托帕茲”的小島上盛產黃色的橄欖石,當地人誤稱其為黃寶石。另一種說法認為是由焚文“Topas”衍生而來,意即“火”。1737年一個名叫亨克爾的人用Topaz一名描述德國盛產的黃寶石而得名。托帕石的礦物學名稱為黃玉,黃玉又稱為黃寶石。

 

托帕石為含水的鋁硅酸鹽礦物,化學分子式為Al2[SiO4](FOH)2,成分中F(OH)的比值變化不定。屬斜方晶係。晶體形態多呈斜方柱狀,柱面常具縱紋,集合體形態為柱狀、粒狀、塊狀。

顏色:為無色、淡黃、深黃、棕色、天藍、粉紅、紅、淡綠和褐色等。

玻璃光澤:透明至半透明。

折光率:1.619-1.627,雙折射率0.008-0.010,色散0.014。多色性清楚。

硬度:8,密度:3.49-3.57/立方釐米。

解理髮育:性脆。在長、短波紫外線的照射下,各種顏色的托帕石顯示不同的熒光。

依據顏色,一般可分為酒黃色、無色、藍色、綠色、紅色托帕石。其中上等的深黃色者最為珍貴,顏色越黃越好。其次是藍色、綠色和紅色者。用天然無色黃玉經輻射加溫處理後的藍色黃玉、黃色黃玉已經大量投入市場,其顏色淡雅艳麗,性質穩定,一切特性與天然托帕石基本上無差異,無法鑒別,但是在出售時應註明“改色黃玉”
