How Big of a Diamond Should I Buy?

A one carat diamond is very large for a wedding ring.

0.38 Carats

The average size for the diamond of an engagement ring is 0.38 carats, according to Jewelry Secrets. Diamonds and other precious gems are measured in carats; one carat equals 200 milligrams. Although you could go bigger, a 0.38 carat diamond is appropriate and sometimes better if the woman has slender fingers.

Depends On The Woman and Your Budget

You should purchase a diamond that fits your budget. Also, consider the size of the woman's fingers, according to Diamond Buying Guide. Diamonds look bigger on women who have small fingers. If the woman's hands and your budget are larger, a one carat or bigger diamond will be acceptable.

Bottom Line

The ideal size diamond for an engagment ring is one that you can afford. While many women would love to have a large diamond, most will understand that you have budgetary constraints. Keep in mind, however, that you can always get a bigger diamond by going with a lower-quality stone.
