false topaz
Noun: 1. A yellow quartz: A type of quartz mineral that is yellow in color. This term specifically refers to the mineral's appearance, which resembles topaz but is chemically different (silicon dioxide, SiO₂, versus aluminum silicate fluoride hydroxide for true topaz).

- Topaz: The distinct gemstone which false topaz resembles.

"False topaz" is not a scientific term but a commercial or descriptive one. It highlights the difference in value and composition between quartz and true topaz. The term itself is rarely used in modern gemology, where "citrine" is preferred.
