Is it true that the price of a diamond increases exponentially as its carats increase, especially as it gets close to 1?
Prices fluctuate, but the short answer is yes. The dramatic increase is because larger pieces of a rough diamond are needed to produce larger sized diamonds. These pieces of rough cost more. The good news is that prices you’ve seen in the “real world” are inflated. In this day and age, you can get a higher quality diamond for similar or better prices from a reputable Internet vendor.
