RUBY
Rubies are precious stones and a member of the corundum family. Rubies range in colour from the classic deep red, pink, purple to brown. Rubies are extremely hard, only diamonds are harder. During the renaissance, people thought that rubies could counteract poison. Laboratory-produced rubies were created in the 1890's and they are difficult to distinguish from natural rubies. The biggest ruby in the word is the Raviratna, which weighs 3,600 carats.
