Rubies are red gemstones with a solid red color, although the precise color of rubies can range from blood-red to orangy-red, purple-red, brown-red, or even a pink-red tone. It is made from corundum, a crystalline form of aluminum oxide. The red color of this stone comes from trace amounts of the element chromium, which replaces aluminum in the mineral and changes its color. But in our Gradient cursor pack with Ruby Gradient cursor, it's just a nice decoration.
