Learn about the four elements that weigh when it comes to placing value on one of these stones.
Trends and fashions determine demand and this in turn establishes how much customers would be willing to pay for a stone. Many romantics say that, ultimately, the final buyer may be the one who sets the price for the gem depending on the sensations it generates.
Carving: refers to the way the stone was carved. This is perhaps the most complex factor, because it requires the convergence of other elements, such as cut, brightness and angles.
Here we check that the angles of the facets coincide, that they give the stone more light refraction and more dispersion (breaking the light in its spectral colors), and that it is well shone.
This aspect is very important because if you have two stones, an emerald type and another with a teardrop shape, and both have the same characteristics in tone, crystal, cleanliness and carat weight, the emerald cut costs more, because this cut refracts better the light, gives more life and concentrates the color in a suitable way.
Hue: the human eye cannot accurately identify and classify the different types of green in emeralds. That is why a measure was created that allows ordering the color in intense, medium and light tones.
The intense ones are more valued, but this has more to do with the taste of the buyer. In any case, if one presents an ideal color and does not have an adequate size, cleanliness and glass; it is probably not well valued in the market.
Crystal: emeralds are crystals that took millions of years to create and the perfect combination of various elements: chromium, iron, and vanadium. According to this parameter, they are classified as transparent, translucent or opaque. The more transparent, the more expensive, because that is how its beauty stands out.
Cleaning: some of the elements of nature that interacted to give life to an emerald left their lags within them, filling them with impurities called inclusions, which can be crystals or minerals such as calcites, quartzites, pyrites or dolomites; fluid, traces left by the gem when it is forming, or cracks, which are usually embellished with oils and resins.
One of the most characteristic fluid inclusions of these stones are the triphasic ones, made up of a liquid, a gas and a solid.
An emerald is clean to the extent that it has the fewest possible inclusions. Thus, the carat of one of these gems could cost up to 50 million pesos.
