GIA Color Scale
The price of a diamond is generally calculated by its clarity, color, and carat weight, as illustrated with our diamond value calculator. The other major impactor of a diamond’s value is the quality of the cut —its proportions, brightness, fire, and scintillation—which, together with clarity, color, and carat make up the 4Cs. Other factors that affect the value of a diamond include diamond material and the presence of fluorescence in the diamond. To account for such characteristics that are unique to each diamond, our diamond calculator presents a range of prices.
To receive in-person guidance beyond the 4Cs from trusted and experienced jewelers, we welcome you to our Newton location. Please schedule an appointment to learn more about diamonds and see the precise differences, and all your options, firsthand.
