Ruby and garnet are both precious stones, but there are some differences between them that set them apart.
Ruby gemstone
Ruby is a type of mineral called corundum and is typically red in color, although it can also be pink, purple, or a dark red. It is one of the most valuable gems and is often used in jewelry, especially in engagement rings. Rubies are formed from the mineral aluminum oxide and get their red color from small amounts of chromium in the crystal structure. The intensity of the red color depends on the presence and concentration of chromium. The most highly prized rubies are a deep, rich red color.
