We have organized our lessons into three categories. You may have seen other places list the 4 C's or the 5 C's (Cut, Clarity, Carat, Color, and Cost). We only have three lessons (Cut, Clarity and Color) because all features influence cost and carat size is not relevant to how well a diamond is made.
Our intention is that you learn about diamonds and become educated in the diamond buying process. With proper education, buying a diamond is not complicated. These lessons are designed to guide you in purchasing a diamond successfully.
