碧璽英文名稱Tourmaline，礦物學名為電氣石，是非常特殊的寶石，因其受到熱力或壓力，會自然產生微量的電流並釋放遠紅外線，故而得名。相傳慈禧太后最喜愛碧璽，常佩帶碧璽維持美貌。然淨透度高的碧璽產量並不多，如果再加上色澤飽滿、清透無暇，那就更是難得了，而這種兼具保健養身與美麗時尚的珠寶飾品，可想而知絕對是價值不斐！

用紅、橙、黃、綠、藍、靛、紫還不足以形容繽紛豔麗的碧璽，它的顏色多樣性，如夏日的絢爛彩虹，還有一種雙色碧璽(紅加綠)，俗稱西瓜碧璽，總是給人如陽光般暢快喜悅的心情！碧璽產地豐富，從巴西一直到非洲各國馬達加斯加、奈及利亞、剛果…等，或是中亞的阿富汗及中國的雲南、西藏均有出產，大克拉數、質地乾淨、色澤鮮明的紅碧璽價格與四大貴寶並駕齊驅，人稱「紅寶碧璽」。每年在蘇富比及佳士得的拍賣會中都屢創佳績，其中含銅的藍綠色Paraiba碧璽，受喜愛的程度尤高成交價可見一斑。

Tourmaline (tur-mah-Leen) is a crystal boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors. The name comes from the Sinhalese word "Turmali" (තුරමලි) or "Thoramalli" (තෝරමල්ලි), which applied to different gemstones found in Sri Lanka.

Treatments

Some tourmaline gems, especially pink to red colored stones, are altered by heat treatment to improve their color. Irradiation is almost impossible to detect in tourmalines, and does not, currently, impact the value. Heat treatment is also used to enhance tourmaline. Heavily-included tourmalines, such as rubellite and Brazilian paraiba, are sometimes clarity-enhanced. A clarity-enhanced tourmaline (especially paraiba) is worth much less than a non-treated gem.
