Evaluating the value of a natural diamond: What is the price for a 4 carat diamond?
What is a 4 Carat diamond?
It's a diamond that weighs 0.8 grams and has an average diameter of 10.40 millimeters when it is round in shape.
In the context of buying or selling a diamond, knowing its value is of paramount importance.
However, amidst terms such as cut, clarity, or symmetry, it is not uncommon to feel disoriented and encounter difficulties in estimating its price.
Discover our introduction to this world made especially for you, and be sure to be able to accurately estimate the value of your stone!
What gives a diamond its value?
Know that a 4 carat stone can cost as much as 40,000€ as well as over 250,000€.
The notion of "carat" is frequently put forward to evaluate the value of a diamond, but it is essential to understand that elle is only one aspect among others. The clarity, color and cut play roles that are just as crucial, if not more, depending on the criteria you prioritize.
The Carat
Confusion persists around the term "carat" which is frequently used incorrectly to describe the size of a diamond, when it actually characterizes its mass. Even if a properly cut diamond generally displays a similar size for an identical carat weight, it should be noted that a 4 carat, round shaped diamond will not always precisely measure 10.25 mm in diameter.
The size of a 4 carat diamond varies depending on its shape. For example, a 4 carat round diamond, cut to ideal proportions, measures about 10.20 mm in diameter and has a depth of 6.20 mm. Other diamond shapes may have different dimensions, offering a larger or smaller surface area. 4 carat princess cut diamonds measure about 9.00 mm x 9.00 mm x 6.30 mm, while emerald cut diamonds have dimensions of 10.50 mm x 7.50 mm x 5.10 mm. Asscher, radiant, cushion, oval, pear-shaped, heart-shaped, marquise, and trillion cuts also have specific dimensions for a 4 carat diamond, offering a variety of choices depending on aesthetic preferences.

The cut ("cut" in English)
The cut of a diamond refers to the size of its culet (the pointed bottom part of your diamond).
The dimensions of this part play a crucial role in how light is reflected, thus impacting the brilliance, fire, and scintillation of your diamond.
The classification of this feature ranges from "poor" to "excellent".
At Celinni, our specialists are committed to offering you stones classified between "very good" and "excellent".
The color ("color" in English)
The color of the diamond, which corresponds to the hue of the stone, is divided into two distinct categories:
- Colorless to slightly yellow diamonds, representing the most common hues (classified from D to Z).
- Special color diamonds, often referred to as "Fancy color diamonds", include diamonds with various hues such as green, yellow, red, blue, purple and pink.
The clarity ("Clarity" in English)
When talking about the clarity of a diamond, we refer to the possible presence of impurities that could alter its brilliance.
A classification, from "I3" (many internal and external impurities visible to the naked eye) to FL (without internal and external imperfection), has been established.
The quality referred to as "commercial", frequently found in large brands, is in a H-SI quality (White on the edge of nuanced - Impurities that are "hardly" visible to the naked eye).
Additional elements such as symmetry, fluorescence, polishing, certification, and even the shape of your stone are criteria not to be overlooked, as they can influence the total cost of your gem.

The price of the diamond is not the price of the final piece of jewelry!
Remember that the estimation of a diamond's price only concerns the stone itself. It is imperative to add to this the cost of the setting (we recommend 18 carat gold or platinum - To learn more, read Link: "PRECIOUS METALS FOR YOUR JEWELRY"*), labor costs, the seller's margin, and even the brand's reputation, depending on the structures, to get an estimate of what a piece of jewelry might cost.
All these elements can significantly influence the final amount of your bill.
By going through the Celinni showrooms for your purchases, you benefit from direct manufacturer production, custom-made jewelry, guidance from our experts, and controlled prices (up to -70% on market prices!).
