There is a slogan that "'A Diamond is forever." This is because the stone is a symbol of deep, everlasting love, as well as the fact that it's the hardest substance known on earth. It is also the gem that marks the 60th anniversary of marriage and is the birthstone for the month of April. It's believed that the First Diamonds were discovered at least 3,000 to 6,000 years ago in India. Warriors in ancient Greece wore the gem as it was thought to strengthen them and make them invincible.
A Diamond has to go through a lot before it reaches a jeweler's display case. It forms deep in the earth under extreme heat and pressure. It's ejected violently upward until it arrives at or near the earth's surface. It's forced from its hiding place by nature or by man. Then it's cleaved, cut, and polished until its natural beauty shines through. The Roman Naturalist Pliny stated; "Diamond is the most valuable, not only of precious stones but all things in the world."
