Natural Black Diamond Beads Strand

Diamond is the birthstone for the month of April.  A special kind of eruption called a kimberlite eruption brings diamonds to the Earth's surface from the upper mantle of the earth's crust by way of extreme pressure from expanding gasses. But this isn't your everyday volcanic activity—in fact, scientists believe that the last kimberlite eruption happened over 10 billion years ago.  This means that the diamonds we see today in the market are literally billions of years old.  The ancient Romans and Greeks believed that diamonds were tears cried by the gods. It is the hardest stone known to man with excellent fire and brilliance which is the main reason for its popularity.
