The mineral that is glassy, colorless, and capable of scratching glass is quartz. Quartz has a hardness of 7 on the Mohs scale, which allows it to scratch glass, typically rated at 5.5. It often appears in a variety of forms, including clear and transparent varieties like rock crystal.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
Fluorite is a mineral that is harder than calcite but won't scratch glass. Calcite has a hardness of 3 on the Mohs scale, while fluorite has a hardness of 4. However, glass typically has a hardness of about 5.5, making it too hard for fluorite to scratch.
It is glassy.
A mineral that can scratch glass but not a streak plate is quartz. Quartz has a hardness of 7 on the Mohs scale, which allows it to scratch glass (which has a hardness of about 5.5) but is harder than the streak plate, typically made from porcelain, which has a hardness of around 6-7. Therefore, while quartz can leave scratches on glass, it will not produce a streak on a streak plate.
Fluorite is a mineral that is harder than calcite, which has a Mohs hardness of 3. Fluorite has a hardness of 4, making it harder than calcite but still not hard enough to scratch glass, which typically has a hardness of around 5.
Diamond is the hardest mineral that can scratch a steel knife or window glass.
A mineral that will scratch with a window glass but not with a knife blade is a mineral with a hardness between 5.5 and 6.5 on the Mohs scale, such as orthoclase or peridot.

The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
Quartz will scratch glass, as its hardness is usually around 7. Pyrite, on the other hand, has a hardness of 6 to 6.5, meaning it would not be able to scratch glass.
A few minerals that do not scratch glass come to mind . . . talc, asbestos, mica, for instance.
Diamond is the only mineral that can scratch glass but not leave a streak on a streak plate. Glass has a hardness of around 5.5 on the Mohs scale, while a streak plate typically has a hardness of around 6.5. Diamond, with a hardness of 10, is able to scratch glass but not the streak plate.
Fluorite is a mineral that is harder than calcite but won't scratch glass. Calcite has a hardness of 3 on the Mohs scale, while fluorite has a hardness of 4. However, glass typically has a hardness of about 5.5, making it too hard for fluorite to scratch.
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
Glass that sat out in the southern. Nevada sun a little too long.
Your answer depends on the composition of the 'fake diamond' and the composition of glass. Each mineral has a rating on the Mohs Scale of hardness. The harder mineral will scratch the softer mineral.
A diamond has a hardness of 10 on a scale of 10 known as Mohs Hardness Scale. A diamond can scratch any other mineral. It isn't the only mineral that can scratch glass thou, quartz, corundum,garnet, among others
