__Diamonds__ media type="file" key="3.wav" width="300" height="50" I picked diamonds as my topic because they are exspensive and i want to know why. Diamond sparkles because it has a high refraction. Refraction means the ability to bend light with the ability to bend light diamond can make its self sparkle. Diamonds are so hard because they have been buried so deep so long. It takes no more than a billion years to form a diamond from coal. Corundum can not scratch a diamond because diamond is more than 4x harder than corundum. A legend about diamond is called the star of south Africa its were a boy found an 18.3 carrot diamond. That's a big diamond! Diamonds can be transparent or opaque they can also be colorful or colorless. I bet now you can see why i chose diamond as my topic.

Note from Mr. VanOrden. I like your questions I think you'll find the answers very interesting. I recently used a saw that had diamonds on the blade. Why do you think it would help to have diamonds on a saw?
