The price of a diamond is influenced by "the Four C's": cut, clarity, color, and carats. This Demonstration shows how each of these factors affects the overall price, calculated by fitting with a generalized linear model. This model applies only to Round cut diamonds, not to fancier cuts such as Princess, Marquise, or Heart.

The data for the model was obtained from using a VBScript webscraping script. In total, 35,000 Round cut diamonds were included in the analysis.
