The average size for the US couple is one carat, while most European couples stay around 0.5-0.6 carat. Those in the Mid-Atlantic region will spend nearly $2,000 more than couples in the Midwest. Younger couples tend to choose between one and two carat diamonds, while older couples seem to opt for the higher end.

The average price of a 1.5 carat diamond is currently $8,557 (see price chart below). 1.5 carat diamonds can cost anywhere from $2,978 - $19,714 depending on the diamond's shape, color, clarity, and other factors.

That being said, and as big and bold as it may be, a 2-carat diamond ring shouldn't feel too large or bulky on your finger, especially if you opt for a diamond cut that is a bit shallower and is placed in a setting that doesn't protrude too high off the band itself.

Given that the average engagement ring is between 1 and 2 carats, it might initially seem that way. It's true that a 3-carat engagement ring certainly stands out. But it is also manageable and light enough to wear on your finger every day without feeling weighed down.
