No......Topaz is an 8 and Talc is a 1....talc is the softest on the scale
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.

the hardness of Topaz is 8 on moes hardness scale
no,calcite is ranked number 3 on the mohs scale of hardness. topaz is ranked number 8 on mohs scale of hardness. 10 is the hardest(diamond) 1 is the softest(talc) look it up!
Feldspars generally have a hardness of 6 on Mohs' hardness scale.
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.
Mohs measures relative hardness (quartz is harder than orthoclase; topaz is harder than quartz), but it doesn't accurately tell HOW MUCH harder something is than something else. There is another scale, called the Rockwell, which does this.
Topaz comes next, then corundum, then diamond is hardest with a hardness of 10
includes: Quartz, Topaz, Corundum, and Diamond. Look up MOHS Hardness Scale. It shows minerals (1-10) softest to hardest. :)
Aquamarine has a hardness of 7.5 to 8 on the Mohs scale, making it a durable gemstone suitable for everyday wear in jewelry. However, it can still be scratched or damaged by harder materials, so care should be taken to protect it.
Malachite has a hardness of around 3.5 to 4 on the Mohs hardness scale. This means it is relatively soft and can be easily scratched by harder materials.
Hornfels typically has a hardness of 5.5 to 6.5 on the Mohs scale. It falls between the hardness of apatite and feldspar.
