Gemfields (LON:GEM) was named "Best Basic Resources" firm at the UK stock market awards.
The awards, now in their third year, aim to highlight firms that are providing shareholder value. The judging panel includes industry professionals and retail investors.
Other nominees in the basic resource category included the mining giant BHP Billiton (LON:BLT), gold miner Mwana Africa (LON:MWA), precious metals leviathan Polymetal International (LON:POLY) and potash play Sirius Minerals (LON:SXX).
Gemfields' chief executive Ian Harebottle said: "We were delighted to accept the Best Basic Resources award at this year’s UK Stock Market Awards.
"Gemfields has had a ground breaking year so far, kicking off with the acquisition of Fabergé, strong production figures for 2012 and the announcement of Mila Kunis as the global ambassador of our rare coloured gemstones. Other companies nominated in this category are first class and we are honoured to have been nominated amongst them.”
Earlier this week, the firm unveiled glamorous actress Mila Kunis as the new face of its new print advertising campaign.
The actress will be featured in a global advertising programme that will run in publications such as Vogue, Vanity Fair, Bazaar and W.
The advertising blitz is just one of many initiatives in a multi-pronged consumer campaign that Gemfields will roll out for 2013.
