Rubies, on the other hand, are a specific variety of corundum that are red in color. The red color is caused by trace amounts of the element chromium in the mineral. The finest rubies are a deep, rich red color and are highly prized for their beauty.
It's important to note that the color of a sapphire or ruby is not the only factor that determines its value. Other factors such as clarity, cut, and carat weight also play a role in determining the value of a gemstone.
In conclusion, sapphires and rubies are both varieties of corundum but have distinct colors. Sapphires come in a wide range of colors, while rubies are red in color. Both are valuable and beautiful gemstones that can make a great addition to any jewelry collection.
