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 middle 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 seem 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 may result in quite a difference in appearance. A diamond during a north-south setting could seem much smaller than one going east-west.

Diamond settings

The way a diamond is seated, or set, during 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 fashionable in diamond rings due to their presentation and therefore the way they secure the gem in situ. they are doing this by a metal strip completely or partly enclosing the diamond. you only don’t want the metal strip to dwarf the diamond.
Halo settings encircle a middle 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 recognition of this setting.
