Ruby is defined as red corundum. The presence of chromium is largely what makes a corundum gemstone red. All other varieties of corundum, anything not red, are classified as sapphire. Although popularly associated with the color blue, sapphires include all non-red colored corundum gems.
Keeping this in consideration, is a red sapphire the same as a ruby?
Scientifically speaking, rubies and sapphires are the same mineral (corundum). Both are made of alumina and oxygen, but they just differ in color. When a corundum is red, it is classified as a ruby, and when it's blue, it is called a sapphire. Sapphires are blue when they contain traces of iron and titanium.
