Diamonds 101
CUT, CLARITY, CARAT, and COLOR are known as the “Four C’s” in the Diamond business. They are the combination of qualities used to establish a diamond’s value. The finest stones possess the rarest quality in each of the 4C’s. When selecting a diamond, we suggest a stone that offers the best combination of the 4C’s. Understanding the diamond scale will help you make an informed decision, and ultimately our clients discover their unique combination of 4C’s that make a particular diamond the best fit.
