Topaz is a silicate mineral composed of aluminum, fluorine, and silicon. Its chemical formula is Al2SiO4(F,OH)2. The color of topaz can vary depending on the impurities present in the crystal lattice.
topaz has a hardness of 8 on the mohs hardness scale, quartz has a hardness of 7. topaz will be able to scratch quartz, but quartz can never scratch topaz.
Ruby,Emerld,Topaz,Dimond and Sapphire are most expensive
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
includes: Quartz, Topaz, Corundum, and Diamond. Look up MOHS Hardness Scale. It shows minerals (1-10) softest to hardest. :)
Three minerals that can scratch quartz are topaz, corundum, and diamond. Topaz has a hardness of 8 on the Mohs scale, while corundum, which includes sapphires and rubies, has a hardness of 9. Diamond, the hardest natural material, ranks 10 on the scale, making it capable of scratching all other minerals, including quartz, which has a hardness of 7.
Your question is unclear. Topaz is a mineral.
Hundreds of minerals are found in Brazil, from diamonds to topaz to quartz.
they are both minerals and birthstones
Topaz, tetrahedrite, azurite, malachite :)

Yes. With the exceptions of coral and pearl, all gemstones are minerals.
It's carbonates
I dont know, I have been seacrching Google myself!! :(
Topaz is used to make jewelry mainly!
Not in the truest sense, in that they have not occurred naturally.

There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
