How do we value your diamonds and precious stones?
The value of a diamond is determined by several factors, often summarized under the term 4C : Carat, Color, Clarity and CutThese criteria influence not only the appearance of the diamond, but also its rarity and therefore its value. Here is a detailed overview of these elements:
1. Carat (weight) : Carat measures the weight of the diamond, not its size. One carat is equal to 0.2 grams. Generally, the heavier a diamond, the higher its value, as larger diamonds are rarer. However, two diamonds of the same weight can have very different values depending on other criteria.
2. Color : Diamonds are graded according to their color, on a scale ranging from D (colorless) to Z (slightly tinted with yellow or brown). Colorless diamonds are rarer and, therefore, more valuable. The absence of color allows the diamond to better reflect light, increasing its brilliance.
3. Clarity Clarity refers to the absence of inclusions (internal imperfections) and external flaws on the diamond. A perfect diamond, without any inclusions or imperfections visible to the naked eye, will be much more valuable. Inclusions affect the brilliance and visual appearance of the diamond, so the fewer there are, the more valuable the stone is.
4. Cut : Cut refers to how the diamond was cut and polished. It is a determining factor in the diamond's brilliance. A well-executed cut maximizes the reflection of light through the stone, resulting in exceptional brilliance. A poor-quality cut, even if the color and clarity are high, can diminish the stone's beauty and value.
In addition to these 4Cs, several other factors can influence the value of a diamond:
- Rarity : Some diamonds may be considered particularly rare due to their origin, history, or unique characteristics (such as pink or blue diamonds, which are extremely rare).
- Origin : The origin of the diamond can also affect its value. For example, some diamonds from reputable mines or with a particular historical provenance may be more highly valued.
- Certificates and Expertise : Diamonds certified by recognized gemological laboratories (such as GIA, the Gemological Institute of America) will have a higher value, because they have been evaluated by experts who guarantee their authenticity and characteristics.
- Market demand : Finally, market demand and trends play a role. For example, certain types of diamonds may increase in value based on fashions or consumer preferences.
And your precious stones…
Gemstone valuation relies on several key criteria. Here are three of the most important:
1. The color:
Color is one of the most important criteria for assessing the quality of a gemstone. It is usually analyzed in terms of tint, saturation and secondary shade. For example, for diamonds, color is measured on a scale ranging from D (colorless) to Z (yellow or brown tint). The more vivid, deep, and uniform a gemstone's color, the higher its value. This is especially true for stones like sapphire, emerald, or ruby, where color plays a key role in valuation.
2. Clarity:
Clarity refers to the presence or absence of inclusions (internal impurities) and visible flaws on the stone's surface. The clearer and purer a stone is, the higher its value. Inclusions can diminish the stone's brilliance and transparency, affecting its appearance and value. Gemologists use a clarity scale to classify stones, from “flawless” (without visible flaws) to “included” (inclusions visible to the naked eye).
3. The carat (weight):
The carat measures the weight of the gemstone, not its size. One carat is equal to 0.2 grams. Generally, the heavier a stone, the rarer it is and, therefore, the more expensive it can be. However, a stone's value doesn't depend solely on weight; a smaller stone with better color or clarity can be more valuable than a larger one with visible imperfections.
