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.
What else can I help you with?
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.
Is a ruby magnetic?
No, ruby is not magnetic because it does not contain any magnetic properties or elements within its structure. Ruby is a type of corundum that is composed of aluminum oxide with trace amounts of chromium responsible for its red color.
Is sapphire attracted to a magnet?
No, sapphire is not attracted to a magnet because it is a type of corundum which is a non-magnetic material. Magnets primarily attract materials that contain iron, nickel, or cobalt. Sapphire is a form of aluminum oxide which does not exhibit magnetic properties.
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.
Can corundum be scratched by diamond?
