Muzo and Chivor emeralds of Colombia

Colombian emeralds are the oldest deposits of emeralds in world discovered so far. The Muzo emerald mines and the Chivor emerald mines have produced the most hard and shiny stones so far and now the stones from that reigion is considered a very precious gem. As the stone is fully crystallized or matured, they are harder and have lesser fissures (hollow spaces) compared to other origin emeralds, due to this the emerald does not usually dries up quickely.

They are popular for their pure shiny green color and brilliance. Comparatively these have better color, clarity and luster/shine compared to their counterpart mined emerald gemstones such as Zambian which have more bluish tones or Russian stones which are light in color shade overall.

All Colombia mined emeralds are not necessarily premium in quality, but are also found in economic commercial qualities.

Colombian Emerald Price

The worth of a Colombian emerald can be $10/ct to over $20000/ct depending on the below mentioned factors of cut-polish, color, clarity and carat weight.

Clarity: clearer and cleaner looking the gem stone is more it will be valued so less cracks and fissures with less inclusions as they make the stones cheaper. The common inclusions in these emeralds are cavities containing gas bubbles and liquids also rock salt crystals are packed as inclusions appearing as calcite rhombus single-single spikes and pyrite crystals.

Color: with the amount and even-ness in spread of color which should be vivid ie. not be too dark and not too light with no appearing color zoning. Generally the color in Colombian emeralds comes lighter which is not good. The color in a valuable stone mined here should be deeper and with a tint of bluish in it.

Carat Weight, Treatment and Cut: Bigger the stone is in size with these above criterion the more rare it will be and thus more valuable. The common accepted treatments are oiling which is reversible and resin filling; resin filled emeralds stand second in valuations. Minor or no oil ones are considered best in quality and remains same wistanding with time as even if oil dries out the stone will not turn patchy. Then comes if the stone is faceted or cabochon cut and symmetry ie. adequate proportions and quality in cut, the polish on stone which highely affects the appearence. There should be no scratches on surface or open cracks.

The mines the emerald belongs to in Colombia affects the pricing like the lapidary (raw stone) from old mines of Muzo and Chivor have more demand so higher rates. The amount of oil in fractures or presence of fissures is also a significator of quality and thus price.

Transparency and Brilliance: Only transparent to semi transparent stones are considered as gems, and translucent or opaque has minumum value. The stone needs to be transparent with shine that is a natural property in rough stone and can be enhenced but cutting skills.

Other factors include the shapes like an emerald cut emerald (octagon step cut) is always demanded over round or oval shape.

Treated / untreated emeralds: Oiling is a commonly accepted practice. The inner cracks / fissures in an emerald makes it look much included and dirty. White patches are seen or clusters of bubbles when there are empty colorless fissures in the stones, so oil gets absorbed in those spaces easily making the fissures and patches dissappear temprerily but once the oil dries up emerald comes in its original form and sometimes significant detioration in quality is seen, now if an emerald has less inner fissures and cracks it will be a minor or no oil emerald as it has less scope or hollow space to absorb oil and thus those are more durable and better in quality then emerald whose clarity is altered with significant amount of oil.

Colombian Emerald Mines

Major mining regions in Colombia are eastern regions of Andes mountain range between Cundinamarca and Boyaca. Chivor, Coscuez and Muzo which are most popular emerald mining regions here others include La Pita, Penas Blancas these pits are both government lesed and private and from these mines comes finest premium quality of emerald. All the mines show a slight difference in the characteristics of stones produced due to geographical differences which are difference of color shade, hue clarity luster / brightness and most important is type of inclusions present. So in Colombian origin emeralds identifying difference on basis of mines needs a lot of expertise and only few experienced people who are from long in the trade and manufacturing can only recognize.
