Occurs in pegmatites and high-temperature quartz veins, also in cavities in granites and rhyolites. A maximum of ~30 % of the F site is occupied by OH in natural topaz, although in some very rare cases OH-dominant members have been described in high-pressure rocks, see Unnamed (OH-analogue of Topaz) (Zhang et al., 2002). A pure synthetic OH analogue of topaz has been synthesised under. Topaz has a specific gravity that ranges between 3.4 and 3.6. This is quite high for a mineral composed of aluminum, silicon, and gaseous elements. This high specific gravity causes it to be concentrated into placer deposits by stream currents.
