In addition, Gemfields also holds controlling interests in various other gemstone mining and prospecting licences in Zambia, Mozambique, Ethiopia and Madagascar.

Gemfields has developed a proprietary grading system and a pioneering auction platform to provide a consistent supply of coloured gemstones to downstream markets, a key component of Gemfields' business model that has played an important role in the growth of the global coloured gemstone sector.
