VALUE OF THE COLOMBIAN EMERALD

It is well known that Colombian emeralds are the most expensive in their category. While some Colombian stones can cost up to $10,000 USD, others can be found for only $30 USD. It all depends on the quality of the stone. Younger stones with an opaque hue and lighter color are usually found in the lower part of the price scale. The stones that cost thousands of dollars are translucent and dark green.

Inclusions are crucial to the value of emeralds. Even though this type of gemstone is known to contain imperfections, it is important to note that clearer stones with fewer inclusions will be more appreciated than darker stones with more evident inclusions.

COLORS OF THE COLOMBIAN EMERALD

The most sought-after colors range from bluish green to pure dark green, also known as MUZO green, and have a deep but not oppressive tone. The most expensive stones on the market have a high degree of transparency, a uniform distribution of colors, and no discernable color zones. The value of the stone will be greatly reduced if the colors and tones are excessively yellowish or bluish, indicating that it is not an emerald but rather a different gemstone from the beryl family.

The bright green color of the best Colombian emeralds is unmatched in nature.

Chrome, vanadium, and iron are the substances responsible for the well-known color of the stone. The hue of the stone depends on the relative proportions and the presence or absence of each trace element in the sample.

SOURCES OF COLOMBIA'S EMERALD

The majority of mines in Colombia are:

• Muzo
• Chivor
• Coscuez

The most well-known and oldest mine is Muzo. It is believed that this mine was discovered by the Spanish conquistadors in the 16th century, who forced the indigenous tribes to exploit it. The emeralds from Chivor are considered to be of better quality and are distinguished by their bluish tint. The stones from Coscuez, on the other hand, have various characteristics. However, these are only generalizations that do not accurately reflect each mine.

PROPERTIES

The different qualities of Colombian emeralds are discussed in this article. Gemologists are able to distinguish real stones from their synthetic counterparts thanks to two essential visual characteristics. These two characteristics are luminescence and absorption spectrum.

ABSORPTION SPECTRUM

The spectrum of an emerald is incredibly unusual and unique in its kind. It presents weak lines in red and blue as well as strong absorption in the violet. Some Zambian emeralds that contain iron present lines similar to those of an aquamarine stone and an emerald.

Pleochroism, a characteristic transition between blue and yellow-green, can also be observed in emeralds.

LUMINESCENCE

The luminescence of an emerald is quite distinctive, just like the absorption spectrum, and will help professionals to definitively identify an emerald.

•  The stones that have not been treated are generally inert and exhibit a low red-orange to red luminescence, in ultraviolet (UV), long waves (LW) and short waves (SW).
• The oil in an emerald has a weaker short wave and a moderate yellow-green long wave.

Fluorescence can be extinguished if iron is present in the components of the emerald.
