In Gemfields, which mines precious stones in Zambia and Mozambique, they said that the sale of precious stones will constitute a "significant part" of the company's revenues in the next 5-10 years.
According to Reuters, at the moment, the sale of stones brings only a small part of the company's total revenue.
Gemfields receives about 90% of its revenue from auction sales of emeralds, rubies and amethysts from the company's fields in southern Africa.
It is reported that the CEO of Gemfields, Ian Harebottle (Ian Harebottle), said the company plans to create a stable global market for colored gems, which will promote their image component in the same direction in which Anglo American De Beers promoted the image of diamonds from London to Shanghai .
Harbottle also said that his past experience in business suggests that the trade in precious stones can bring about 40% of the company's revenue.
"Trade in precious stones can definitely bring a significant part of the company's income," he said.
The company's revenue for the six months to December 31, 2014 increased by 57% to $ 103.4 million.
Gemfields expects to receive permission to trade in precious stones in Zambia, which also holds the Kagem mine, owned by the company by 75%.
In addition, the company already owns a permit for the extraction of rubies and sapphires in Mozambique and Sri Lanka, respectively.
