Actual diamond size
Before purchasing a diamond, one should make sure it looks its weight.
It's important to understand that
carat weight does not equal face-up size.
Two diamonds of exactly the same weight (and shape) can vary quite considerably in face-up size. This depends on the proportions of the cut (e.g., deep cuts will face up smaller).

About Depth Percentage
Depth percentage is one of the most important measurements as it plays a critical role in diamond's
appearance. If a diamond is cut too deep or too shallow, light leaks out, making
the stone less brilliant and fiery. Deep cuts also add hidden weight.
Diamonds that fall out of recommended depth range are generally less desirable and usually best to be avoided.

Face-up size evaluation for 2.3 carat Princess (7.27×7.27×5.23mm)
The face-up size of this 2.3 carat Princess
(7.27×7.27×5.23mm) is within the normal range for
2.3ct diamonds of this shape.
Compared to 2.3ct
Princess reference diamond (see below), this diamond is of adequate
size when viewed from the top. In short, all is OK, this diamond looks its weight.
Proper face-up size should play an important role when buying a diamond. When a diamond is set in a ring, your eyes will only see the face-up area, so you should make sure it's of adequate size. Adequate size also indicates a good cut, meaning better light performance. For example, if given a choice between a poorly cut 2.3 carat Princess with less sparkle and the same face-up size as a well cut 2.1ct Princess, which one would you choose?
The importance of face-up size
Diamonds are sold by weight (carats), but it's important to understand that weight doesn't equally translate into physical size, especially spread. Two diamonds of the same carat weight can vary greatly in spread, meaning that one diamond can appear larger than the other, even though they weight exactly the same.Proper face-up size should play an important role when buying a diamond.

The bottom line:
A diamond must look its weight. This one does. Thumbs up.
2.3 carat Princess reference diamond
Since there are no specific ideal proportions defined for Princess cuts,
an estimation formula is used to calculate the Princess reference diamond.

Note: Princess diamonds with face-up area of within 8% lower
and 12% higher than reference Princess diamond area
are considered to be of adequate face-up size.
Face-up size evaluation for 2.4 carat Cushion (7.4×7.4×5.2mm)
The face-up size of this 2.4 carat Cushion
(7.4×7.4×5.2mm) is slightly out of normal range for
2.4ct diamonds of this shape. Compared to 2.4
carat Cushion reference diamond,
this diamond appears a bit too small when viewed from the top, which means it's
probably a borderline chubby.
A chubby is a diamond with hidden extra weight that looks smaller than it should when viewed from the top. Hidden weight is typically a result of a poor cut usually linked to oversized girdle, deeper pavilion, and/or steeper crown.
In order to maximize profits, diamond cutters tend to retain as much weight from the rough as possible. This practice, however, can have detrimental effects on the stone's face-up size and its optical qualities. Poorly proportioned stones look duller and sparkle less than well cut stones. Chubby stones also look smaller.

The bottom line:
One should never sacrifice beauty for weight.
You probably don't want to pay for extra weight that doesn't add anything to the beauty.
You want a stone that looks its weight. Sizewise, this 2.4ct Cushion looks like a well cut 2.05ct Cushion.
2.4 carat Cushion reference diamond
Since there are no specific ideal proportions defined for Cushion cuts,
an estimation formula is used to calculate the Cushion reference diamond.

|||||||||||||||||||
Note: Cushion diamonds with face-up area of within 9% lower
and 12% higher than reference Cushion diamond area
are considered to be of adequate face-up size.
* Estimated Face-up area: Face-up area of Cushion cuts
is only an estimation (±5%). Due to uniqueness of each stone,
it's impossible to accurately calculate face-up area given only a diamond's measurements.
Face-up Area per Carat
Face-up area per carat is calculated by dividing face-up area of the diamond with
its carat weight. It tells you how many square millimeters of the top surface area
a diamond is showing or would show for 1 carat weight. This can be useful when comparing stones
of similar weights as it tells you how much spread per carat you will get.
Note: Face-up size does not linearly grow with carat weight,
which means the heavier the stone, the smaller its face-up area per carat (e.g., 1ct stone will have
higher face-up area per carat than 2ct stone).
Face-up area per carat
for 2.3ct Princess (7.27×7.27×5.23mm):
Top surface area = 52.85 mm²
Weight = 2.3ct
Face-up area per carat = 52.85 ÷ 2.3 = 22.98mm²/ct
Weight = 2.3ct
Face-up area per carat = 52.85 ÷ 2.3 = 22.98mm²/ct
Face-up area per carat
for 2.4ct Cushion (7.4×7.4×5.2mm):
Top surface area = 49.28 mm²
Weight = 2.4ct
Face-up area per carat = 49.28 ÷ 2.4 = 20.53mm²/ct
Weight = 2.4ct
Face-up area per carat = 49.28 ÷ 2.4 = 20.53mm²/ct
