Colombian Emeralds trading is a relatively simple process. If you are a consumer looking to buy fine Colombian Emeralds you have different options depending on: Quantity, Quality and Price.
Buying Emeralds gemstones from an International trader is simple. The customer contacts the trader and arranges a viewing for any given gemstone, if the customer likes the gemstone and thinks its price is fair enough, he ultimately buys it.
Buying Emeralds gemstones from Colombian traders is somewhat more complicated. The customer contacts the trader and arranges a viewing for any given gemstone, the viewing takes place normally in Colombia, and sometimes it could take place at the customers location of choice outside Colombia. If the customer likes the gemstone and thinks its price is fair enough, he ultimately buys it.
Both methods have serious flaws. The first one implies that any given International trader has already bought Emeralds from either, a Colombian trader or another International Trader, which ultimately means the customer pays a lot more for any given Emerald. Given that traders set overprices sometimes as high as 200% the amount they payed originally, Emeralds bough from International Traders are extremely over priced. International traders normally buy a given amount of Emeralds and that ties customers to buy only what is available in their stocks.
