Thinking of the diamonds leads one to think of diamond rings and of marriage. The word diamond is derived from the Greek for “invincible” and diamonds are one of the hardest substances on earth. It's no wonder then we associate this gem with marriage, a bond between two people which is ideally invincible. But diamond jewelry is not only for celebrating an engagement. The diamond is also April's birthstone.
The diamond has had a long and varied history. For most of Ancient history, the diamond remained in India. Diamond jewelry was worn by all levels of society and the color of the diamond indicated the wearer's social status. Diamonds didn't become a regular adornment in the Western world until the Middle Ages. By then, diamond jewelry was believed to keep one healthy. Queen Elizabeth the first was given a diamond necklace to keep her safe from infection. Diamond jewelry was even worn by some to ward off the plague.
Now we know that diamond jewelry cannot keep away disease. But we are attracted to its brilliance, to its eternal quality, which is why we associate it with marriage. But we can also convey how brilliant, how eternally wonderful we think a loved one is with diamond jewelry, especially one born in April.
