[EN] Topaz is a silicate mineral of aluminium and fluorine with the chemical formula Al2SiO4(F,OH)2. Topaz crystallizes in the orthorhombic system and its crystals are mostly prismatic terminated by pyramidal and other faces. Pure topaz is colorless and transparent but is usually tinted by impurities; typical topaz is wine, yellow, pale gray or reddish-orange, blue and brown coloring. Coloring can also be made white, pale green, blue, gold, pink (rare), reddish-yellow or opaque to transparent/translucent. Imperial topaz is yellow, pink (rare, if natural) or pink-orange. Brazilian Imperial Topaz can often have a bright yellow to deep golden brown hue, sometimes even violet. Many brown or pale topazes are treated to make them bright yellow, gold, pink or violet colored. Some imperial topaz stones can fade on exposure to sunlight for an extended period of time.

[CZ] Topaz je kremician hliníku obsahující fluor, jeho chemický vzorec je Al2SiO4(F,OH)2. Krystalizuje v kosoctverecné soustave a krystaly mají vetšinou sloupcovitý protažený tvar zakoncený plochami tvorící pyramidu. Cistý Topaz je bezbarvý a pruhledný, ale obvykle je zabarvený necistotami; typické je vínové, žluté, svetle šedé, cerveno-oranžové nebo modré a hnedé zbarvení. Zbarvení muže být také bílé, svetle zelené, modré, zlaté, ružové (vzácné), cerveno-žluté. Krystaly mohou být nepruhledné až pruhledné / prusvitné. Imperial topaz je žlutý, ružový, nebo ružovo-oranžový. Brazilské topazy Imperial casto mohou mít jasne žlutý až tmave zlatavý odstín hnedé, nekdy až fialový. Mnoho hnedých nebo svetlých topazu se zpracovává tak, aby byly jasne žluté, zlaté, ružové nebo fialové. Nekteré topazy mohou blednout pokud jsou vystaveny po delší dobu slunecnímu zárení.
