What a lab looks for in topaz
- Irradiation and heat: nearly all blue topaz has been irradiated and heated, and some pink topaz is heated from another colour.
- Coatings: thin surface layers used to create rainbow effects or very strong colours.
- Identity: telling topaz apart from citrine, aquamarine, yellow sapphire and glass.
- Synthetics: uncommon in topaz, but still checked.
