Colombian emeralds are enjoying an all-time high, and this trend to continue in 2014.
The emerald world as we know it today is primarily dependent on the production of gemstones from three sources: Brazil, Colombia and Zambia. Until very recently each country played a fairly static role in terms of market preference. Colombian emeralds dominated the high end, Zambian gems occupied the middle, and Brazilian stones were considered to be more commercial. While this positioning is still pretty much intact, there are always exceptions and some Zambian and Brazilian stones may rival even the best stones from Colombia.
Most emeralds are already included and fractured throughout and dealers and cutters select the best and cleanest stones for faceting. There are of course differences between individual stones, but there is no important mining area that produces emeralds more stable or less included than stones from other deposits. This means that visible inclusions in emeralds are common and expected and emeralds are judged with a greater emphasis on color and transparency and included stones are accepted. While emeralds without eye-visible inclusions do exist, these stones are extraordinarily rare. Some inclusions in emerald are referred to as jardin, (meaning garden in both French and Spanish) and may consist of networks of tiny liquid filled inclusions and minute fissures that permeate the gem evoking the appearance of a lush garden. These inclusions also impart the emerald with a distinctive sometimes hazy appearance because they diffuse and spread light through the gemstone.
