Colombian / Columbian origin emeralds are considered as the most valued and sought after of all the emeralds. Colombia located in south America is pioneer in production of emeralds to the world market. Colombian emeralds popular for their pure shiny green color and brilliance comparatively have better color, clarity and luster/shine then compared to their counterpart mined emerald gemstones as Zambian which have more bluish tones or Russian stones which are light in color shade overall, but it is not necessary that all Colombia mined emeralds are premium in quality they are also found in economic and low qualities.
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 even, 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.
Major mines in Colombian emerald mining region are Chivor and Muzo which are most popular others include La Pita, Coscuez, Penas Blancas 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 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. The GIA, GRS or Gubelin swiss lab gives the origin in certificate which is based just on origin country and almost do not mention name of the mines so ask your Colombian emerald supplier if she can tell.
