Why Use This App?

  • Diamonds are expensive and pricing is complex.
  • Our app provides an instant estimate based on:
    • Carat Weight
    • Cut Quality
  • Helps buyers and sellers find fair market value.

The Data Source

We use the diamonds dataset from the ggplot2 library. It contains prices and attributes for ~54,000 diamonds.

```{r}
summary(diamonds$price)
model <- lm(price ~ carat, data = diamonds)
coef(model)
