Topaz forms in pegmatites and high temperature quartz veins. It is deposited by fluorine-rich vapors in rocks of rhyolite composition and forms in cavities in granites and rhyolites. Brazil is the largest supplier of topaz.

Pure topaz is colorless and transparent but is usually tinted by impurities; typical topaz is wine, yellow, pale gray, reddish-orange, or blue brown. It can also be made white, pale green, blue, gold, pink (rare), reddish-yellow or opaque to transparent/translucent.

^That answer is 100% false. Yellow topaz is NOT the same as citrine. Though they appear similar in color, they are chemically very different. Citrine is a quartz crystal and topaz is mineral crystal and therefore the more expensive of the two stones.

Pure quartz, traditionally called rock crystal (sometimes called clear quartz), is colorless and transparent (clear) or translucent. Common colored varieties may contain other minerals and be translucent or even opaque.

To distinguish topaz from glass or quartzes (e.g. citrine), we should observe the hardness. Topaz is a fairly hard gemstone, meaning it is resistant to scratching. It is 8 on the Mohs hardness scale (diamond is 10, sapphire is 9). A scratch test will determine whether a stone is topaz in most cases. You can perform a scratch test by taking a piece of quartz or other material with a hardness around 7 and scratch it against the "topaz". If you don't want to risk the stone scratching, even if it's fake, you can choose to scratch it on the girdle (the unpolished rim around the gem).
