Rubies are made of the mineral corundum, which is composed of aluminum oxide with the element chromium giving the gemstone its red color. The intensity and shade of red in rubies can vary based on the amount of chromium present in the crystal structure. Inclusions of other minerals or elements can also affect the ruby's appearance and value.
