What is the value of an Emerald?

Emerald is a precious stone of enormous value and is 20 times rarer than a diamond. In addition to being considered one of the most beautiful gems , it is also among the most valuable.

The most valuable emeralds today come from Colombia, along the Bogotá mountain range, which provides almost all of the world's emeralds.

The parameters used to calculate the value of an emerald and to be able to recognize a real one from a fake one are: purity, color, transparency and size.

Purity. Emeralds almost always have inclusions inside them (most of the time visible to the naked eye), finding a pure one is extremely rare. Because of the inclusions, cutting can sometimes be complicated, because there is a risk of ruining the gem. For this reason, the cut that is most often used is the step-cut or “emerald” cut , ideal for preventing the emerald from being ruined during processing and helping to maintain its brilliant color. The cut is essential to highlight the stone's brilliance. 

Color. Emeralds are available in a wide variety of colors that depend on the different amounts of chromium, vanadium, and iron present in the environment in which they form. The color can vary from bluish-green to yellow-green . An emerald with a bluish-green tone is the most valuable, because it is more sought after and rare. The color must have the right degree of saturation and hue.

Size. Large emeralds are very rare to find, but it cannot be assumed that large ones are the most valuable. Inclusions are more likely to be found in large stones, which can affect clarity.

Transparency. The value of an emerald depends on how transparent the stone appears. Gems with many inclusions appear less transparent, and dark green emeralds absorb little light and appear more opaque.
