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).
Here you can see the actual sizes of 0.2ct Trillion (4.58×4.58×1.83mm) and 0.15ct Trillion (4.11×4.11×1.64mm) as they would appear on a ring and finger.

Face-up area is a measure of the size of the diamond
when viewed from the top (as set in a ring).
It tells you how big the diamond is at the girdle plane. It's important for a diamond to have sufficient face-up size for its carat weight.

Quick Buying Guide
Diamond prices vary greatly as they depend on the combination of unique characteristics (4Cs - Cut, Color, Clarity, and Carat). For best value, it's important to choose the combination that will reduce the price without having a negative impact on appearance.
Each shape has its own recommended balance of qualities that will give you the most bang for your buck. Below is a quick buying guide to give you an idea, but for more detailed explanation, please see the complete buying guides for the respective diamonds (links below).

Depth percentage for 0.2 carat Trillion (4.58×4.58×1.83mm)
Depth percentage of Trillion cut is the ratio of the total depth (measured from table to culet)
to its width. The total depth percentage of this diamond
is 40%, which is OK.
(Recommended depth percentage for Trillions is between 32% and
48%)
Depth percentage for trillions is calculated with the following formula:

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 0.2 carat Trillion (4.58×4.58×1.83mm)
The face-up size of this 0.2 carat Trillion
(4.58×4.58×1.83mm) is within the normal range for
0.2ct diamonds of this shape.
Compared to 0.2ct
Trillion 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. You probably wouldn't want a poorly cut 0.2ct Trillion that is less sparkly and faces up the same as a well-cut Trillion of a smaller weight.
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.

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 0.2ct Trillion (4.58×4.58×1.83mm):
Top surface area = 13.01 mm²
Weight = 0.2ct
Face-up area per carat = 13.01 ÷ 0.2 = 65.05mm²/ct
Weight = 0.2ct
Face-up area per carat = 13.01 ÷ 0.2 = 65.05mm²/ct
Face-up area per carat
for 0.15ct Trillion (4.11×4.11×1.64mm):
Top surface area = 10.47 mm²
Weight = 0.15ct
Face-up area per carat = 10.47 ÷ 0.15 = 69.8mm²/ct
Weight = 0.15ct
Face-up area per carat = 10.47 ÷ 0.15 = 69.8mm²/ct
