How It Sparkles
The way a diamond is cut and polished affects how it sparkles. It takes a very skilled craftsperson to do this.
Diamonds that are clear and colorless are harder to find. These are the more valuable ones. Most diamonds have a little bit of yellow or brown color.
A diamond‘s basic crystal shape is the octahedron. The surface of an octahedron sometimes displays little triangle shapes called “trigons.”
Most diamonds formed more than a billion years ago! They form about 100 miles (161 kilometers) below the earth’s surface, where the temperature and pressure are just right. Diamonds are the hardest natural material on earth. They stand for fearlessness and invincibility, and are a symbol of love.
