The mineral you are describing is likely quartz, particularly in its clear or colorless form, known as rock crystal. Quartz exhibits a hexagonal crystal structure and is relatively hard, scoring a 7 on the Mohs scale, which allows it to scratch a steel file. Its various colors can arise from impurities or inclusions, leading to varieties such as amethyst or citrine.

In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
The mineral that can scratch feldspar and can be scratched by garnet is quartz. Quartz has a hardness of 7 on the Mohs scale, making it capable of scratching feldspar, which has a hardness of 6. Meanwhile, garnet has a hardness of around 6.5 to 7.5, allowing it to scratch quartz but not all varieties of garnet will scratch quartz.
The preform scratch test is primarily used to determine the hardness of minerals. This test involves scratching the surface of a mineral with a standardized material (often a metal or another mineral) to assess its resistance to scratching. The results help classify the mineral according to the Mohs hardness scale, which ranges from 1 (talc) to 10 (diamond). Additionally, the nature of the scratch (depth, ease of scratching) can provide insights into the mineral's overall physical properties.
The Mohs hardness of serpentine is 2,5-3; it a soft mineral. Not scrached by a graphite pen; scratched by fingernail, copper etc.
Yes, quartz is a silicate mineral composed of silicon and oxygen atoms. It is one of the most abundant minerals in the Earth's crust and has many different varieties, including amethyst, citrine, and rose quartz.
A harder mineral will scratch a softer one.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
it is hardness
Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !
There are many ways to make crystals from scratch.
false a mineral can not scratch any mineral harder than itself
A diamond is the only material that cannot be scratched by any other than itself.
No, not a true crystal
Halite can scratch gypsum.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
