The Emerald is a member of the beryl family of minerals. The green crystals grow slowly within metamorphic rocks and are restricted in size by the rock, making large Emeralds rare and costly. Although this gemstone is relatively hard and durable, it must be protected from blows because the inclusions found within make it susceptible to breaking.
May’s birthstone is the vibrant Emerald. The deep green of the Emerald symbolizes spring’s new growth and rebirth. And the Emerald is as soothing as fresh rain in the garden. Often tiny fractures or inclusions lay within the Emerald, the French call "jardin," or garden, because of their resemblance to foliage. The Egyptians were known to engrave Emeralds with the symbol for foliage to represent eternal youth, and to bury these jewels with their dead. The ancient Romans associated this gemstone with fertility and rebirth, and dedicated it to Venus, the goddess of love and beauty.
Some people believe that wearing an Emerald brings wisdom, growth, and patience. And as any couple in a long-term relationship would agree, all of these qualities are essential for a successful and lasting love. This may explain why a gift of Emerald for an anniversary -- or anytime -- is considered symbolic of love and fidelity.
