Diamonds

Facts

Diamond, the hardest natural substance on earth, is pure carbon that has crystallized through exposure to intense high heat and pressure miles below the earth's surface in its crust. They were formed 1-3 billion years ago and were brought to the surface through volcanic eruptions. Diamonds are found mostly in volcanic rock called "kimberlite." Most sources believe the tradition of giving a diamond ring to represent a couple's engagement began in 1477 when Archduke Maximillian of Hamburg presented one to Mary of Burgundy. At that time however, it could only be afforded by the wealthy and the trend really didn't take hold until years later. The birthstone for April, it also is the suggested gift for the 10th, 60th and 75th wedding anniversaries.

Fascination

The name diamond comes from the Greek word "adamas" meaning unconquerable. The ancient Greek philosopher Plato believed in life among gems and held diamond as the noblest. A diamond's qualities—brilliance and durability—were considered powerful medicine and it was thought that diamond powder from flawless white stones would give health, energy and long life when swallowed.

Caring for Diamonds

Known as nature's hardest substance, it is a common misconception that diamond is indestructible. Hardness refers to resistance to scratching or abrasion, different from toughness, which means resistance to breakage. With a sharp or severe blow, the diamond may chip or fracture. This why it is important to treat your diamond rings and other jewelry with care. Whenever convenient, you should take the stone to a jewelry professional and ask him or her to clean your jewelry and check the stones for security.
