Our Story
Our passion for transparency, legitimacy and integrity shines through everything we do. So does our focus on the ‘big three’ coloured gemstones: rubies, emeralds and sapphires.
We have taken considerable strides in tailoring our portfolio to reflect this, identifying suitable sapphire opportunities in Africa to complement our thriving ruby and emerald operations. We’ve expanded our marketing activities to boost demand for coloured gemstones and maintain the utmost operational transparency, too.
What we do
We oversee the responsible mining and marketing of coloured gemstones from some of the world’s finest gemstone deposits, while ensuring they benefit as many citizens as possible.
With a great respect for the natural world and the communities that inhabit it, we believe that those who mine gemstones should do so with transparency, legitimacy and integrity.
R&G 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).
Responsible sourcing for us means implementing industry-leading policies and practices across operations, transparency in our auction sales process, an active role in working groups to modernise the sector, projects to improve health, education and livelihoods for the communities around our mines and conservation efforts (#conservationgemstones) to protect Africa’s great wildlife and biodiversity.
What we do
In our operation in Mozambique, we have also introduced a technologically advanced coloured gemstone sort house, with state-of-the-art optical sorting machines.
Our proprietary grading system, pioneering auction platform and active marketing presence have all played a significant role in the rise of African gemstones.
As well as supplying the majority of the world’s rough rubies and emeralds, we work with international jewellery brands and other creative partners to raise the profile of African coloured gemstones through inspiring collaborations.
Our mission
R&G mission is to be the global leader in African emeralds, rubies and sapphires, promoting transparency, trust and responsible mining practices.
Driven by our values and our belief that coloured gemstones should create a positive impact for the country and community from which they originate, we seek to do things differently. To maintain a considered balance between people, profit and the environment.
We partner with cutting-edge jewellery designers and some of the world’s most iconic brands to showcase coloured gemstones; we establish schools, health clinics and agricultural programmes to support our local communities.
