Gemfields is the operator and 75% owner of both the Kagem emerald mine in Zambia (believed to be the world's single largest producing emerald mine) and the Montepuez ruby mine in Mozambique (one of the most significant recently discovered ruby deposits in the world). In addition, Gemfields also holds controlling interests in various other gemstone mining and prospecting licences in Zambia, Mozambique, Ethiopia and Madagascar. Gemfields' outright ownership of Fabergé - an iconic and prestigious brand of exceptional heritage - enables Gemfields to optimise positioning, perception and consumer awareness of coloured gemstones through Fabergé designs, advancing the wider group's "mine and market" vision. 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.
