What Is Topaz?
Topaz is a neosilicate mineral (Al₂SiO₄(F,OH)₂) that forms in pegmatites and vapor cavities in rhyolite lava flows. With a Mohs hardness of 8, it's one of the hardest silicate minerals, making it excellent for jewelry. While naturally colorless, trace elements and irradiation create its famous spectrum of colors.

-
Crystal System: Orthorhombic (forms prismatic crystals)

What Color Is Topaz? The Complete Spectrum
Contrary to popular belief, topaz occurs in more colors than just blue. Its palette includes:
| Color Variety | Cause | Rarity & Value |
|---|---|---|
| Imperial Topaz | Chromium impurities | Most valuable (orange-pink) |
| Blue Topaz | Irradiation treatment of colorless stones | Most commercially available |
| Sherry Topaz | Iron impurities (yellow-brown) | Mid-range value |
| Pink Topaz | Chromium + natural irradiation | Rare and expensive |
| Colorless | Pure form without impurities | Historically significant |
| Mystic Topaz | Artificial coating (rainbow effect) | Novelty value |
Note: Natural blue topaz is extremely rare - most commercial blue topaz is colorless material that's been irradiated and heated.
