Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing well-cut diamonds higher on the Diamond Quality Pyramid than deep or shallow-cut diamonds. Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance and ultimately, value.

Cut also refers to shape—round, square, pear, or heart, for example. Since a round diamond is symmetrical and capable of reflecting nearly all the light that enters, it is the most brilliant of all diamond shapes and follows specific proportional guidelines. fancy shapes will have their own guidelines to be considered well-cut.

Many people are confused about how diamonds are priced. The best explanation is that asking for the price of a diamond is like asking for the price of a house. A real estate agent can’t quote you a price for a house without knowing its size, condition, location, etc. This is the same when buying a diamond. A diamond’s beauty, rarity, and price depend on the interplay of all the 4Cs—cut, clarity, carat, and color.

The 4Cs are used throughout the world to classify the rarity of diamonds. Diamonds with the combination of the highest 4C ratings are more rare and, consequently, more expensive. No one C is more important than another in terms of beauty and it is important to note that each of the 4Cs will not diminish in value over time.
