Is amethyst a silicate or nonsilicate?
non-silicate. Sapphire is Al2O3, alumina or corundum, contaminants such as chromium give it color.
What are the six classes of non silicate minerals?
The six classes of non-silicate minerals are carbonates, sulfides, sulfates, halides, native elements, and oxides. Each class is defined by the chemical composition and structure of the minerals within that group.
Is corundum magnetic?
Small traces of iron are responsible for much of the color found in corundum (saphire) gems. Ruby, however, does not contain iron and will not be affected by a magnet. To be technical however, I should point out that corundum is not magnetic. Corundum will not attract other pieces of iron to itself (as far as I know). To simply answer that corundum is not magnetic would have been misleading.
Why is corundum magnetic?
Corundum, also known as aluminum oxide, is not magnetic. It is a diamagnetic material, meaning it does not have any magnetic properties and is very weakly repelled by magnetic fields.
What mineral can corundum scratch?
Corundum can scratch all minerals except diamond, making it the second hardest mineral on the Mohs scale with a hardness of 9. Diamond, with a hardness of 10, is the only mineral that can scratch corundum.
Is sapphire a silicate?
No, sapphire is not a silicate. Sapphire is a variety of the mineral corundum, which is composed of aluminum oxide (Al2O3). Silicates are minerals that contain silicon and oxygen as their main components, such as quartz and feldspar. Sapphire belongs to the oxide mineral group, not the silicate group.
Is amethyst a silicate or nonsilicate?
non-silicate. Sapphire is Al2O3, alumina or corundum, contaminants such as chromium give it color.
What is the plural of corundum?

Is corundum hexagonal or cubic?
Corundum ( (Al_2O_3) ) is hexagonal in crystal structure.
Which crystal system does corundum have?
Corundum is in the trigonal crystal system.
What important uses does corundum have?

What do you call a red corundum?
Red corundum is called ruby.
What is the chemical name for corundum?
Corundum is aluminium oxide, Al2O3.
What is the only mineral that can scratch corundum?
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 !
What do they call red corundum?
Red corundum is called ruby.
What percentage of rubies is corundum?
100% of rubies are corundum. "Ruby" is a name made up by the gem trade for the mineral known as corundum, when it is red.
Can quartz scratch corundum?
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
