The value of a natural diamond derives from its rarity as a finite, natural gem. This rarity and finiteness make natural diamonds valuable. Natural diamonds are formed by the heat and pressure of the Earth, from 1 to 3 billion years ago, making a natural diamond the oldest thing you will ever touch.
Think about the significance of your favorite piece of diamond jewelry, or, better yet, your engagement ring. The diamond in an engagement ring represents the rarity and exclusivity of the couple’s love.
