The Diamond is the birthstone for people born in the Year of the Dog. Diamonds are associated with power, protection, strength, courage, loyalty, friendship, originality, purity, fidelity and innocence. Diamonds are referred to as "The Stone of Morality" in at least one Chinese legend. Diamonds are usually colorless, but may have a variety of hues, depending on the impurities that are present.
Rubies are also associated with the Year of the Dog.
