Titanium

The term color of a diamond actually refers to the absence of color. When a diamond is colorless, it acts like a prism, letting light pass through it effortlessly. When light is broken down, it is transformed into a rainbow of color. Typically, the closer a diamond is to colorless, the more valuable it becomes. Every Diamonds International diamond is selected to offer premium beauty and value. The scale shown below demonstrates the subtlety and various grades of a diamond's color.
