Ruby cannot be considered either as it is not an element. It is primarily made of corundum, which is a compound of aluminum (a metal) and oxygen (a nonmetal).
Corundum is not magnetic.
The overwhelming use, by far, of corundum is in the manufacture of abrasives--sandpaper, grinding wheels, etc. Gem grade corundum is used in jewelry.
Corundum can scratch almost any mineral that isn't diamond.
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's luster is metallic.

Corundum.
Corundum is not magnetic.
Corundum ( (Al_2O_3) ) is hexagonal in crystal structure.
Corundum is used for jewlery
Corundum is in the trigonal crystal system.
Red corundum is called ruby.
Pure corundum is clear in color.
Corundum is aluminium oxide, Al2O3.
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 !
