What Is The Average Diamond Size For An Engagement Ring In The US?
According to a survey by creditdonkey.com, the national average diamond size for an engagement ring in the US hovers around one carat. That brings the average engagement ring cost to about $6,000.
Here is a partial look at engagement ring size by US state:
- Maryland: 1.75 ct
- Michigan: 1.69 ct
- Illinois: 1.59 ct
- Alaska: 1.49 ct
- New York: 1.47 ct
- Texas: 1.47 ct
- Florida: 1.47 ct
- Virginia: 1.44 ct

Diamond Size Explained
A diamond’s “size”refers to the diamond’s carat size. However, there are other important factors that impact how big a center stone diamond looks:
Shape: This refers to how a diamond looks geometrically: round brilliant, radiant, oval, pear and emerald cut diamond etc. Some diamond shapes allow a lighter weight diamond to look bigger by spreading it out.
Depth: This refers to the measurement from a diamond’s bottom tip (“culet”) to its top surface (“table”).
Other factors: The direction of a setting can result in quite a difference in appearance. A diamond in a north-south setting may seem much smaller than one going east-west.
Diamond Types Of Diamond Settings
The way a diamond is seated, or set, in a ring can influence its size appearance, too:
- Prong settings are just what they sound like. Prongs hold onto the diamond.
- Bezel settings remain very popular in diamond rings because of their presentation and the way they secure the gem in place. They do this by a metal strip completely or partly enclosing the diamond. You just don’t want the metal strip to dwarf the diamond.
- Halo settings encircle a center diamond with smaller diamonds. (Think: a diamond diva with backup singers/ blingers.) A halo setting makes a diamond look much bigger, which accounts for the popularity of this setting.

Famous people are just like us — except maybe with more ring bling:

- Jennifer Lopez: 15-18 carat diamond ring ($1 million)
