Corundum is commonly found in gemstone deposits, such as in Myanmar, Sri Lanka, India, and Madagascar. It is also found in smaller quantities in various other locations around the world, including the United States, Australia, and Russia. Mining for corundum typically involves searching in areas where it is commonly associated with other minerals.
No, corundum is a very hard mineral, scoring a 9 on the Mohs scale of hardness. A fingernail typically ranks around 2.5 on the scale, so it would not be able to scratch corundum.
Corundum.
Corundum is in the trigonal crystal system.
The unknown mineral would be topaz. Topaz lies between apatite and corundum on the Mohs scale, making it capable of scratching apatite and being scratched by 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 !

Goldenrock Mine is in the mining-town of Darkwater Crossing. There is Corundum Ore in the mine. There is also a silver vein if you swim a little upwards in the river.
many small ammounts in random locations but there is a mine at darkwater crossing
Corundum.
Iron-breaker mine in Dawnstar is pretty good. Also the quicksilver in the mine across town is real nice.

Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
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.
Corundum ( (Al_2O_3) ) is hexagonal in crystal structure.
Corundum is in the trigonal crystal system.
