Corundum.
Corundum is commonly used as an abrasive in sandpaper and grinding wheels due to its hardness. It is also used as a gemstone in jewelry, with red corundum known as ruby and all other colors classified as sapphire. Additionally, corundum is used in optics, such as in the manufacturing of laser components.
The most common cation in non-organic gemstones is iron (Fe2+ and Fe3+). Iron impurities can give gemstones their color, such as green in emeralds (beryl), blue in sapphires (corundum), and red in rubies (corundum).
Sodium chloride is a compound, not a chemical element.

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).
Garnet typically has a non-metallic luster, appearing more vitreous or glassy than metallic.
The value of the mineral corundum will vary according to its appearance. Gem quality corundum is highly valued. Non gem quality corundum has many industrial uses and is much less highly valued.
