Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Quartz is hard enough to scratch calcite, as it has a higher hardness rating on the Mohs scale. However, quartz is not hard enough to scratch amphibole minerals, which are generally harder than calcite.

Quartz has a Mohs hardness of 7, meaning minerals that are softer than quartz (Mohs < 7) will not be able to scratch it. Some examples include talc (Mohs 1), gypsum (Mohs 2), calcite (Mohs 3), and fluorite (Mohs 4).
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
apatite will not scratch quartz topaz calcite or corundum
Quartz because its harder than calcite and the quartz in thicker.
Quartz is harder than calcite, making it more scratch-resistant. Quartz also has a higher melting point than calcite. Additionally, quartz is typically transparent or translucent, whereas calcite can be transparent, translucent, or opaque.
Quartz is hard enough to scratch calcite, as it has a higher hardness rating on the Mohs scale. However, quartz is not hard enough to scratch amphibole minerals, which are generally harder than calcite.
Quartz would scratch the calcite. Calcite would not scratch the quartz. Calcite will react with dilute hydrochloric acid. Quartz will not. Calcite will exhibit double refraction. Quartz will not. If the crystal forms are intact, quartz crystal may appear six sided with pyramidal terminations. If they are of equal size, the quartz will be heavier.

No.because calcite is softer then feldspar
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
Quartz has a Mohs hardness of 7, meaning minerals that are softer than quartz (Mohs < 7) will not be able to scratch it. Some examples include talc (Mohs 1), gypsum (Mohs 2), calcite (Mohs 3), and fluorite (Mohs 4).
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
