The three attributes that define a gem:
It must be beautiful.
It must be rare.
It must be durable.
The pearl, as you will discover is all this and more!
The diamond is referred to as the King of Gems. This is because of its adamantine quality, its hardness, and its almost invincible structure. The pearl is not as durable as the diamond but it has an unmatched exquisite beauty and because of this, it is considered the Queen of Gems. In fact, the pearl was the world’s first gem and the most valuable of all gems until it was rivalled by the 19th century diamond discoveries.
