The Diamond is the birthstone of April and the anniversary gemstone for the 10th and 60th years of marriage.
Diamonds were discovered in India in 500 B.C., and the name "diamond" comes from the Greek word "Adamas" which means unconquerable - suggesting the eternity of love. Since ancient Greece, diamonds have been the traditional symbol of love, and the ancients believed they were hardened dew drops, splinters from the stars or crystallized lightning.
A diamond is the hardest substance known to humankind, and is made of a crystallized carbon that has unique powers of light reflection. Since diamonds are composed of a single element, they are the purest of all gemstones.
