Gem-A gemmologist, Charles Evans FGA DGA, embarked on an incredible trip to diamond mines in the Kimberley region of South Africa in September 2017, where he was part of a group with exclusive underground access to three of the most historically significant and largest mines of our time.
As part of the experience he visited some of the open cast operations run by junior miners and witnessed multiple methods of recovery and extraction as well as gaining an understanding of the changing face of mining in a setting that challenges the idea that ethical mining can only be small scale and artisanal.
The trip was rounded off with a visit to Botswana for the 11th International Kimberlite Conference.
