What does the evaluation of jewels and precious stones depend on?
The elements that can affect the evaluation of jewels and precious stones are numerous and diversified; however it is possible to summarize the most significant:
Evaluation of jewels: Weight and size
As obvious as it may seem, weight and size are among the elements that most influence the evaluation of the jewels. In the commercial field it is customary to maintain the relationship according to which 1 gram = 5 carats.
It should be underlined that some stones are hardly found in their natural state in a high carat weight (e.g. emeralds, rubies and sapphires): in this case the value of 1 carat of the stone rises exponentially. On the contrary, other gems that are found in large crystals in nature may have lower ratings, as in the case of quartz or topaz.
The gems can take on any color of the visible spectrum even when they belong to the same mineralogical family as happens in the case of tourmalines, garnets, quartzes, topazes.
Color is one of the most relevant characteristics of a stone: in fact, the hue, saturation and brightness of the gemstone define the color and the external appearance of the gemstone.
Although the preference for a color belongs to the sphere of subjectivity, however the value of a stone can also be linked to the saturation and the green hue of the gem itself.
At the same time, it is appropriate to underline how color can be an important aspect in the sales phase but not in the purchase phase: it is in fact essential not to rely solely on the color of the stone in order not to incur hasty and not very advantageous evaluations. By way of example, it can be remembered that, if an evaluation of the precious stones is carried out in an inaccurate way, it is possible that a topaz is confused with an aquamarine (gems with a very different market value).
Influence of light
Gems and, consequently, the evaluation of jewels and precious stones, also depends on the light and phenomena that arise, including refraction, diffraction, reflection and interference. The light can therefore lead to have “strange effects” on a stone so that, sometimes, they can be considered real defects or even strengths.
For example, Alexandrite can vary from a greenish color to a purple red based on the light source that illuminates it.
Unlike the two previous features, clarity is not an external feature that acts on the stone. It is in fact a fundamental element in the price of precious stones which consider substantially its transparency: in general, in the evaluation of a precious stone the less the number of inclusions the greater its value. If inclusions are present, it is preferable that they are as small as possible since, at present, very transparent gems are more appreciated. In this regard, it should be noted that in the case of diamonds there is a special reference scale for the clarity of the stone.
