Topaz

Prized in jewelry for its blue color, topaz is a fine stone that exists under a wide range of colors from pink to orange and blue.
Opinions on the origins of the word “topaz” differ: for some it takes its name from the Sanskrit “tapaz” meaning “fire” while for others it comes from the deserted island of Topazios (now Zeberg) in the Red Sea.
European jewelers have long given a poetic name to the blue variety of this transparent mineral: “Siberian diamond” because of its high density and the glass that emerges after its carving.
