| Ruby is a precious gemstone known for its deep red color. It is a variety of corundum, which also includes sapphires. Rubies are formed under extreme pressure and heat, and their red color comes from chromium atoms replacing some aluminum atoms in the mineral's structure. Rubies are among the rarest gemstones, with large stones being rarer than diamonds of similar size. They are found in river gravels, with Myanmar's Mogok area being a notable source. Rubies are highly valued for their color, with pure red stones without color undertones being the most desirable |
